Types Of Bearings And Their Uses – Bearings play an important role in rotating equipment by reducing friction and creating smooth and efficient movement. There are many types of bearings used in different applications depending on factors such as load capacity, speed and environmental conditions. These are the common types of bearings used in rotating equipment.
4. Sleeve Bearings: Sleeve bearings, also known as plain bearings or bushings, consist of a cylindrical sleeve that provides a low friction surface between a rotating shaft and a stationary component. They are typically used in moderate load, low speed applications such as fans, pumps and small motors. Sleeve bearings need lubrication to function properly.

5. Tapered Bearings: Tapered Bearings are designed to carry radial and axial loads. They have tapered wheels and inner and outer wheels for efficient load distribution. Tapered bearings are commonly used in automotive applications such as wheel bearings, where they can carry both radial and axial forces.

6. Spherical Roller Bearings: Spherical Roller Bearings are designed to carry heavy radial loads and misalignment. They have barrel-shaped rollers that can be misaligned due to shaft misalignment or assembly errors. Spherical bearings are often used in heavy duty applications such as crushers and vibrating screens.
7. Needle Bearings: Needle bearings, or needle bearings, use long, thin cylindrical rollers with a large diameter. They are suitable for applications with limited radial clearance but require high load capacity. Needle roller bearings are commonly used in automotive applications, industrial machinery and aerospace equipment.
8. Angular Bearings: Angular Bearings are designed to carry radial and axial loads simultaneously. They have separated flow paths, which allow them to carry combined loads. Angular thrust bearings are commonly used in machine tools, pumps and gearboxes.
9. Ceramic Bearings: Ceramic Bearings use ceramic balls or ceramic shells, which are high speed, low friction, corrosion and high temperature resistant. They are often used in high-speed applications such as electric motors, turbines and aerospace equipment.
How Rolling Element Bearings Work
It is important to consult bearing manufacturers or experts to consider the specific requirements of the application and choose the most appropriate type of bearing for optimal performance and longevity. Ball bearings use balls as rolling elements. These are determined by the point of contact between the ball and the raceway. Normally, ball bearings rotate very quickly, but they cannot withstand large loads.
Different types of ball bearings are used in industry. Below are the four main types. Among many brands, IKO ball bearings are the first choice for OEM and manufacturing industries for their high quality. Padia Enterprise is proud to be one of the distributors of IKO Bearings in India.
They are easy to maintain and are not very sensitive to operating conditions, so they are used in a wide range of applications. As well as radial forces, they absorb axial forces in both directions. Their low torque is ideal for fast operation.
Angular contact bearings are defined by the contact angle. This means that power is transferred from one corner to another.

This type of bearing is recommended when there is a problem with the alignment of the shaft and the housing and where the shaft can deviate. Self-aligning ball bearings are ideal for absorbing radial forces.
A ball bearing consists of two bearing discs with raceways for the balls. Thrust ball bearings are designed to absorb axial force in one direction only, meaning that the shaft can be positioned axially in one direction. Rolling bearings are a common component of motion systems. They are used in gearboxes, motors, pulleys, propellers, pumps – Rolling bearings to reduce friction and support radial or axial loads whenever the shaft rotates.
The classification of rolling bearings begins with the type of bearing that carries the load – ball or roller. For ball and roller types, the next distinguishing feature is the direction of the main load that the bearing can withstand – radial or axial (that is, thrust). Ball bearings are then classified by outer ring configuration, while roller bearings are classified by roller shape.
There are dozens of options for rolling bearings, and the most common categories are discussed here, including designs, mounting configurations, and applications for specific environments.

Slewing bearings are classified as either ball or roller and then radial or axial (thrust), depending on the type of load they are intended to support. Ball bearings are further classified based on the configuration of the outer ring, while roller bearings are classified based on the shape of the roller.
Angular contact bearings are usually used in a pair or double row design (shown here) to withstand axial loads in both directions.
In the ball bearing family, the deep groove ball bearing is the simplest type, with a race that matches or nearly matches the diameter of the ball. This type is suitable for radial loads and loads in different axial directions, but their bearing capacity is low compared to other types of bearings. Deep Groove ball bearings have a double row design with two rows of balls instead of one for greater load capacity in a relatively small area.
Angular contact ball bearings are designed so that the line connecting the contact points of the inner ring, ball and outer ring runs at a radial angle to the bearing. The contact angle increases the load capacity, but as the bearing can only withstand an axial load in one direction, these bearings are usually used in pairs or in a double row design (generally, two angular bearings placed back to back). axial load in both directions.

Single-angle bearings are four-point contact bearings designed to withstand high axial loads in both directions. They can also withstand combined axial and radial loads where the axial component predominates.
Thrust ball bearings are made of two relatively thin bearing rings (sometimes called bearing plates or washers) designed to carry axial loads in one or both directions by sliding. For transmission bearings, radial loads are usually not allowed, and the speed capabilities are limited (in some cases, their radial loads are as low as 20-30 percent).
A roller bearing, such as the cylindrical bearing shown here, has a greater radial load carrying capacity than a ball bearing using a roller bearing.
Bearing rollers and roller bearings have a higher load capacity and are stiffer than ball bearings of the same size. The type of load they can withstand depends largely on the shape of the roller.

Cylindrical roller bearings can withstand high radial loads, and double-row cylindrical versions have very high radial load capacities and high stiffness in the radial direction. Although standard cylindrical roller bearings cannot carry axial loads, some designs have internal ribs or collars that allow them to carry relatively small axial loads in one or both directions.
Needle roller bearings use long, thin rollers three to ten times their diameter. They have good radial load capacity, but the main advantage of the pin design is a thin cross section for applications where high radial capacity is required but space is limited.
Unlike cylindrical and needle roller bearings, which carry loads with a tapered roller, tapered rollers can carry axial loads in one direction. Tapered bearings can be thought of as sliding versions of angular contact bearings, and like their spherical counterparts, tapered bearings are often used in a pair or double row design to resist axial forces. bearing capacity when a radial load is applied. The tapered design improves rolling properties and reduces friction within the bearing.
Spherical roller bearings use barrel-shaped rollers with two inner threads inclined at an angle to the bearing axis and one spherical outer race. This gives them self-alignment, a very high radial load capacity and the ability to carry axial loads in both directions.
Things To Consider When Choosing Bearings For Your Aluminum Engine
Thrust versions of roller bearings generally match the strength of their radial counterparts, but are capable of handling thrust (axial) loads.
Cylindrical bearings can withstand high axial loads and not radial loads, but they can withstand impact loads.
Similarly, needle thrust bearings can handle high thrust loads but have a much smaller shape than needle bearings.
Tapered bearings can be unidirectional or bidirectional, which means they can carry axial loads in one direction or in both directions. Their radial-type bearings have a “pure” rolling motion, which means less heat and less wear.
