Every machinery has some mechanical parts which are crucial for its appropriate function. Similarly, the role played by mechanical bearings cannot be disregarded. They do look small but their absence can disrupt the function of various processes in machines.

If you want to learn about bearings and the types of bearings, we have it covered in the guide below. So, let's take a look.

What are Bearings?

Bearings are used for improving the rotational movement of a shaft. They are meant to guide it and handle the process of load transferring from the shaft to the frame structure. Bearing is used in machines as a critical component and the rolling processes are highly dependent on it.

Why is Mechanical Bearing Important?

The surface leads to wear and tear when rotating metals come in contact with the other components. It impacts the durability and life of machinery and also impacts its operational efficiency.

Hence, the use of mechanical bearings helps avoid friction and improves smooth motion. These bearings are of small size in the shape of a ball and have a rolling motion.

Bearings reduce friction, improve operational efficiency, and reduce contact with the surface. They also help with handling loads and distributing them evenly.

5 Main Types of Bearings and Their Uses

There are 5 main types of bearings, which have subtypes, and each has a different use. The section below highlights in detail the uses of different types of bearings.

Type 1: Ball Bearing

Ball bearings are spherical balls that are present between the two bearings and they support axial as well as radial loads.

The holes have a component known as a retainer, which supports the balls and keeps them spaced uniformly. Such bearings are made using stainless steel 14401 or 4401 or roller bearing steel.

Deep Groove Ball Bearings

Deep-groove ball bearings consist of deep grooves in their outer and inner raceway, which hold these balls.

It has a simple design and is used in many applications like turbines, water pumps, and gearboxes. These bearings can handle loads and also support speedy rotations.

Angular Contact Ball Bearings

Angular contact ball bearings are meant to transfer force between the two rings, internal and external. Angular ball bearings can handle loads and work with high-speed operations.

Self-Aligning Ball Bearings

Self-aligning ball-bearing has a structure like a cage, which has two rows of balls having equal distance between the inner and outer race.

If there is any type of dynamic or static misalignment, the outer race adjusts the position of the bearing to correct it.

The major advantage of these self-aligning ball bearings is that they have the ability to self-correct their position. They absorb vibrations and shocks. It is used in machines where the chance of misalignment prevails.

Thrust Ball Bearings

The structure of these bearings has a cage that has two rings. The inner race is connected to the rotating shaft. There are two variations of single and double direction in thrust bearings.

In a double direction, the ball moves in an alternating pattern between the rings. These bearings can manage high-speed loads and are also very easy to install. They are mostly used in crane hooks and spindles of machine tools.

Miniature Bearings

Miniature bearings are small-sized ball bearings that are used in spaces that are small and require precise handling of load. The overall diameter of such bearings is less than 20 mm. These ball bearings are used in medical and electronic machines and even help reduce the noise when the machines work.

Thin Section Bearings

Thin section bearings consist of a layer of outer and inner race, which is thin enough to fit in a limited space.

The rolling part of these bearings can be in the form of cylindrical bars or balls. These bearings have very limited weight but ensure high accuracy. They are used in many applications that need high performance like electronics, aerospace, and defense.

Flanged Bearings

The flanged bearing has an extended flange, which is present on the outer race of the bearing. The flange offers to make the attachment strong for the bearing and frame. The flange also has a mounting setup.

These bearings are suitable for handling radial loads and are used in applications that have excessive vibrations.

Type 2: Roller Bearings

Roller bearings consist of different shapes of rollers which help in transmitting stress. The shape of these rollers is conical, cylindrical, or spherical. These rollers help increase the surface area to handle high loads.

These roller bearings support the radial or combined loads and improve the performance of moveable parts by reducing friction.

Cylindrical Roller Bearings

The cylindrical roller bearings have the ability to handle high radial loads as they have a linear contact between rings and rollers. They can support axial forces of moderate levels and are used in drilling rigs or tool spindles.

Spherical Roller Bearings

Spherical roller bearings have spherical rollers in the form of a cage– two rows that are separated. These bearings can roll to reduce friction and also support larger loads from the shafts.

The spherical roller bearings can self-adjust the misalignment of the outer ring of the shaft. These bearings are used in marine propulsion and off-road cars.

Tapered Roller Bearings

Tapered roller bearings have a tapered inner, which is called a cone and an outer, known as a cup, consisting of tapered rollers having a cage between them. The tapered angle of the outer ring has a range between 10 to 30 degrees.

The tapered shape can distribute the axial load of the shaft, which is heavy, and also accommodates the radial loads. They have a compact design, which makes them suitable for limited space. These bearings are used in mining and railway systems.

Needle Roller Bearings

Needle roller bearings are the same as cylindrical ones, but the size differs. The needle roller bearings have a diameter of less than 6mm, and they are also known as low-weight and high-speed roller bearings.

They are suitable for compact spaces and support high radial loads. They are used in applications like piston pin bearings.

Thrust Roller Bearings

Thrust roller bearings consist of a structure the same as thrust ball bearings. It has a length spherical roller rather than a ball, and it can handle heavy axle loads that have no direction.

These bearings are used in heavy duty industries for compressors and turbines.

Cross Roller Bearings

Cross roller bearings have a cross pattern of rollers in cylindrical shape. It has alternative rollers which interact with each other at a right angle.

The arrangement of rollers supports the precision and rigidity in handling radial stresses and axial stresses. These rollers are highly suitable for controlling motion.

Type 3: Plain Bearings

Plain bearings are simple types of bearings and they do not have any rolling elements. They consist of a cylindrical bore which holds the components like shafts.

These bearings are also called bushes or sleeves. They have a plain surface, which states the load is heavy and helps lower friction.

Plain bearings have multiple configurations like washer, flanged, cylindrical, sliding and thrust. They have features like tabs, notches, holes, and grooves that come in contact with the surface and help in reducing friction.

The plain bearings are opted in operations composed of low speed and heavy load where the chances of oscillation and misalignment prevail. Their applications are observed in agriculture machinery and cranes.

Type 4: Fluid Bearings

Fluid bearing tends to replace the metallic bearings using a fluid layer, it can also be composed of gas, air, and lubricant between the rotor and housing surface.

Fluid bearings are applied to moving parts that are not in contact with one another. The fluid helps to hold the load and ensure smooth movement between components. The two types of fluid bearings are as follows:

Hydrostatic Bearings

Hydrostatic bearings work using a pressurized fluid; the fluid is injected between the parts that move under high pressure. It helps in reducing the friction and maintains the movement. The external pressure here helps maintain operation.

These bearings are opted for linear and rotary motion. They are used in gas turbines and spindles of machines.

Hydrodynamic Bearings

Hydrodynamic bearings are bearings in which low friction and load support are provided. They have a fluid that helps to create a bearing film with the help of motion between the contact surface and the journal.

These bearings depend on the speed of rotation, alignment, and viscosity of fluid. They are suitable for turbines and other applications operating at high speed.

Type 5: Magnetic Bearings

Magnetic bearings use electromagnetic force, which helps in suspending and rotating the rotor in a given position. The electromagnetic field is present inside the bearing composed of wires on a ferrous material.

As soon as the magnetic field activates, the force is applied to the rotor component, which makes the magnetic bearing operate at high load and speed.

Active Magnetic Bearings

An active magnetic bearing controls the position of the rotating shaft with its control system. The control mechanisms and integrated sensors process the real-time data, and the position is adjusted by the control unit.

The self-position and real-time monitoring of this bearing help with precision in steam and motion control. These bearings are used in applications like flywheels, turbochargers, and machine tools.

Passive Magnetic Bearing

Passive magnetic bearings have no feedback or active mechanism which adjusts motion. Rather, it has a permanent magnet, which is aligned in a way that makes the attractive and repulsive force to control the rotation and position.

These bearings need less maintenance and are very affordable. They have a simple design and work with noise.

Benefits of Using Bearings

Bearings have many benefits, and some of these are as follows:

• Bearings can reduce the vibration levels and noise.
• Bearings have the ability to handle axial as well as radial loads at the same time which helps to increase load capacity and reliability.
• They can offer simple lubrication and offer corrosion resistance when made using plastic.
• Bearings ensure that the applications feature low maintenance and they themselves have a low cost of maintenance.
• The bearing can handle heavy radicals at a higher speed.

How to Choose Different Types of Bearings?

Car suspension parts play a vital role in the performance of the car. They are responsible for making the ride smooth when driving on rough roads.

However, understanding the different components of car suspension and their functions is important. So, read the guide below and familiarize yourself.

What are Car Suspension Parts?

Car suspension parts consist of tires, shock absorbers, springs, and linkages that connect the car to the wheels. The system of car suspension is very crucial for creating an interaction between the road surface and the tires which helps with car movement.

The core purpose of a car suspension system is that it ensures that the tire stays in contact with the road and ensures traction. It helps with proper vehicle handling and stability to ensure a comfortable drive.

Functions of Suspension Parts in a Car

The main function of the car suspension is to ensure a connection between the wheels and the car. It also ensures traction on the roads. However, the functions of the car suspension can be split into two different points.

The first one is that it absorbs the shocks while the imperfections of roads are encountered. The second one is that the car stays connected to the surface of the road at all times. It helps in preventing the external forces that may take the car off the road.

Components of a Car Suspension Part

The components of a car suspension part are discussed below:

Springs

The role of springs is to work like a shock absorber which helps to absorb all types of shocks that the wheels may pass through due to the imperfection of roads. The springs also help in maintaining traction on the roads and the car moves smoothly.

Anti-roll Bar or Stabilizer

It prevents the vehicle from rolling over and ensures to maintain the balance of the car especially when driving at high speed and making sharp turns.

The bar consists of an iron rod for connecting the right and left wheel lower arms and keeps the vehicle attached to the center.

Damper or Shock Absorber

The damper is known to dampen the motion of the vehicle. It absorbs the energy that is released from the spring's movement and maintains the connection between the road and the tires.

Bumper

The bumper is a component of the car suspension system that involves rebounding and bounding.

It protects the car and consists of materials like rubber which helps in shock absorption. They ensure that the integrity of the vehicle is maintained when there is an expansion or contraction in the springs of the car.

Lateral Control Rod

The lateral control rod is mostly opted for in four-wheeler vehicles. The main task of the rod is to keep the axle held tightly when there is load exerted from the side.

This rod is between the axle of the vehicle and the car body. It also creates a link with the suspension parts and helps to keep the car stable.

Knuckle Arm

The knuckle arm is at the front of the wheels and it connects the components of the wheel with the car’s assembly. They ensure that the car wheels pivot for steering and help in better handling.

Ball Joint

The ball joint consisting of pivot joints manages the horizontal and lateral loads on the vehicles. They can connect the suspension parts so that the movement in different directions is supported.

It also works as a rotation axis when the car turns and ensures an appropriate alignment of wheels.

Lower and Upper Arm

The lower and upper arms of the car are components that connect the car chassis with other parts of the suspension system.

It handles the movement of the suspension system in the up and down position and helps with the ease of turning in vehicles while maintaining stability.

Strut Bar

The strut bar holds the lower arms and lets the front wheel function properly. It helps to enhance the response of steering while maintaining better control of the car. It also reduces the chassis flex and improves the vehicle’s rigidity.

Types of Automotive Suspension Systems

Automatic suspension systems have various types, and some of these are discussed below:

Dependent Suspension System

In a dependent suspension system, when one wheel or component moves, this movement affects the other, which is on a similar axle.

Its design is such that the rear axle creates a connection between both wheels. It is a simple and affordable suspension system but is not commonly opted for.

Independent Suspension System

The independent suspension system is mostly opted for in most modern vehicles.

In this system, the wheel is connected to a specific spring, shock absorber, and solid axle so that they have independent movement. This helps to reduce the impact on the opposite wheel.

The independent suspension system offers a precise alignment and promotes improved handling of vehicles especially at a high speed. However, this system costs more as it has a high complexity.

Semi-Independent Suspension Systems

It has a rigid axle that has coil springs connecting the wheels on a similar axle. However, like an independent system, it has shock absorbers for each side.

Manufacturing Methods for Car Suspension Parts

There are different methods that are used for manufacturing suspension parts for a car, and some of these are discussed below:

Metal Casting

Metal casting companies use processes like die casting and sand casting. It helps to manufacture components of the suspension system like knuckle arms and lateral control.

It uses the heated metal, which is melted and then poured into the molds to attain the required shape of the component. It is an old method that is opted for its affordability and even creates parts that are highly durable.

CNC Machining

CNC machining is also a very commonly chosen method for the manufacturing of suspension parts of a car. It uses computer-controlled tools that move according to the program and create highly precise components.

It is usually used for components like arms, knuckle arms, and strut bars. It can manufacture components that have tight tolerance and excellent surface finish.

Injection Molding

An injection mold is used for manufacturing the components that are used for manufacturing the non-metallic components using plastics.

The suspension components are usually made using metals, and injection molding is not very common but can help with automobile bumpers.

The process of injection molding uses molten material to be poured into cavities where they are left to solidify upon cooling and attain the shape. It is an affordable method that helps in manufacturing lightweight parts.

Forging

The process of forging consists of creating metal components by shaping them using a high force.

It is used for creating components that are strong and durable like linkages, anti-roll bars, and control arms. The suspension parts manufactured using this process are the ones that have high strength and toughness.

Welding

Welding is a method that helps assemble two or more components. The process is used for joining the suspension components to the chassis or the frame of the car.

It heats a small portion of the parts and fuses them onto one another creating a bond with strength. Welding also ensures the security of the joint and creates a stable suspension system.

Importance of Quality Suspension Parts

The suspension parts quality matters a lot as it has many impacts on the vehicle, and some of the reasons this quality matters are as follows:

Impact on Vehicle Performance

The suspension parts quality ensures to maintain the optimal performance of the vehicle and helps with better stability and handling. It can absorb shocks effectively and also makes the ride a comfortable one.

Safety Considerations

Suspension is crucial for the safety of a vehicle. When the parts of the car are of high quality, the stability is maintained when the car is driven on uneven roads or takes sharp turns. It helps to minimize the chance of skidding and protect the passengers.

Iron is a versatile material that is widely used in many applications and industries. There are different types of iron, and each type has a specific use based on its properties. Some of the common types of iron are featured in this guide below; if you want to learn about it, let's read.

Types of Iron

The eight different types of iron are discussed in this section below.

1. Pure Iron

Pure iron, also known as butter iron, consists of 99.8% pure iron, followed by a very negligible amount of manganese and carbon. It originates from an electric arc furnace that has an extremely high temperature, which melts the iron. The trace elements present in pure iron add some properties to it.

Pure iron is used to manufacture gaskets, magnets, and special alloy steels in different industries. It is soft, and hence, for daily use, it has to be mixed with carbon so that it takes a strong form.

2. Cast Iron (White Iron, Gray Iron)

Cast iron has a high carbon content. It has a grained and brittle structure. It retains and distributes heat very well. Hence, it is commonly opted for manufacturing engine blocks, cookware, pipes, and some construction materials.

There are different types of cast iron, and these are as follows:

• White cast iron has a crystalline fracture structure that results from metastable solidification.
• Gray cast iron has a gray fractured surface and flakes of graphite, but it also has ferrite.

3. Pig Iron

Raw iron is pig iron, which has chunky blocks. The production process of this iron type takes place by heating iron ore in a blast furnace. Hot air is introduced in the blast furnace, which leads to blasts.

The pig iron produced has around 90 to 95% iron, 3 to 4% carbon, and some other elements like silicon and manganese. It is harder than pure iron but still not suitable for day-to-day applications.

4. Wrought Iron

Wrought iron was created by blacksmiths and is made by heating iron in a furnace, which is set to reach a specific temperature. After that, it is hammered and shaped, presenting a form of iron that is low in carbon. It has a grainy look and offers excellent resistance against corrosion, being malleable and having high strength.

Wrought iron was previously used for ornaments, railings, and gates. It is still widely used for these purposes today. It is durable and can be reheated and shaped as needed.

5. Stainless Steel

Stainless steel is an alloy of iron that has chromium, molybdenum, and nickel. It is highly corrosion-resistant and is used in applications that need durability and are exposed to moisture. Stainless steel is used to manufacture surgical instruments, kitchen utensils, and even some architectural structures.

6. Carbon Steel

Carbon steel is an alloy of iron which has some carbon in it. It's used in many applications like automobiles, construction, and machinery. The carbon content in carbon steel may vary and create different types, such as low carbon steel, high carbon steel, or medium carbon steel.

7. Alloy Steel

Alloy steel is made using iron, carbon, and some other elements, such as nickel, silicon, manganese, copper, etc. The other elements add up to certain properties of the alloy steel, which make it durable, tough, and strong.

8. Tool Steel

Tool steel, as the name suggests, is used to manufacture dies, tools, and machine components. They are high-alloy steels and have iron, carbon, and other elements, including tungsten, nickel, and molybdenum. These elements give tool steel exceptional hardness and resistance against wear. It also passes through the process of tempering for additional strength.

Conclusion

CNC-machined components are manufactured using a wide range of iron types. When it comes to choosing the right iron type, you have to consider the application of the machined components.

We at DEK can offer you a detailed analysis of which type of iron can be chosen for your specific application and components, and we also offer machining services. So, get in touch with us.

Differences Between Custom Manufacturing vs. Mass Production

When manufacturing components, choosing between mass production and custom manufacturing has always been a very confusing decision. The two of these methods have their own limitations as well as benefits.

Custom manufacturing allows manufacturing products that are produced on a small scale, according to the requirements of customers, and take less time to produce.

Meanwhile, mass production is done for large volumes of similar products. Customized manufacturing is inclined to reduce waste and ensures an immediate turnover.

Custom manufacturing relies on the orders of individual customers, and it works very closely with the client. Custom manufacturing is different from mass production because it uses specialized equipment and tools. These tools ensure that large quantities of components can be manufactured within less time.
