We'll talk about the many types of bearings that are accessible in this post, along with their advantages and disadvantages. We'll also go over how to pick the ideal bearing size for your requirements.

Bearing Types



There are many different kinds of bearings, each created to address particular demands and purposes. The 4 main types of bearings are:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


The most popular form of bearing, ball bearings are used in a variety of machines and devices. They are bearings that use small, hardened steel balls to keep the shaft in place. The balls are positioned between two races, which are circular plates. Roller bearings are also a common type of bearing and use cylindrical rollers instead of balls. Little, pointed needles are used in needle bearings to hold the shaft firmly in place. Thrust bearings use flat plates called races to hold a shaft in place.

The inner diameter (ID) and outer diameter (OD) of a bearing determine its size (OD). The bore, or the bearing's central hole, is measured by something called the ID. The OD is the measurement of the outer race. The width is a measurement of the bearing's width.

Consider the load, speed, and vibration that the bearing will experience while selecting a bearing. The load is the amount of weight or force that the bearing must be able to support. The bearing's speed is the rate at which it will spin. The vibration indicates how much movement the bearing will undergo.

Bearings can be purchased in a variety of locations. One choice is to get bearings from a nearby bearing supplier. Another choice is to buy bearings from a bearings-specific website online.You can get a quote for the bearings you need from several bearing-selling companies using their web-based quoting system.

There are many different types of bearings on the market, and each has benefits and drawbacks of their own. The four most typical bearing varieties are ball bearings, roller bearings, bearing housings, and bearing units. Each type of bearing has a distinct set of qualities that make it more or less suitable for particular purposes.

The most popular form of bearing and the one that is utilized in the most applications is the ball bearing. A set of balls that spin between inner and outer races make up these devices, which are commonly composed of steel or ceramic. Ball bearings are relatively simple and durable, making them ideal for applications where high speeds and/or loads are involved.

Although identical to ball bearings, roller bearings are made to support greater loads. They typically consist of a set of cylindrical rollers rotating between inner and outer races and are constructed of steel or brass. Although less durable than ball bearings, roller bearings are more effective and are therefore better suited for situations involving heavier loads but lower speeds.

It is possible to place bearings onto a shaft or other support structure using bearing housings, which are enclosures that shield them from external pollutants. Bearing housings come in a variety of sizes and shapes and are commonly composed of steel or cast iron.

Self-contained bearings that have already been put together and are ready for installation are known as bearing units. A housing, a bearing, and a seal are often included. Bearing units are available in a variety of sizes and configurations, making them suitable for a wide range of applications.

In terms of rolling bearings, plain bearings, and components for linear motion, SKF is a global leader.


Ball Bearings:


The most prevalent kind of bearings are ball bearings. They consist of a number of balls and two metal rings known as the inner and outer races. In actuality, the bearing rolls on the balls. Typically, the inner race is fastened to the shaft the bearing is supporting. Most frequently, the housing is fastened to the outside race.

Roller Bearings:


Comparable to ball bearings in many ways, roller bearings use cylinders as opposed to balls. Roller bearings are more likely to break under heavy loads even if they can sustain larger loads than ball bearings.

Plain Bearings:



Plain bearings are the simplest type of bearing. Their construction consists of two sliding metal surfaces. To lessen wear and friction, plain bearings can be greased with oil or grease.

When choosing the best bearings for your application, bearing types and sizes are crucial considerations. Bearings come in a wide variety of forms, and each type has a distinct set of advantages and disadvantages that can be found on the market. If you choose the improper kind of bearing for your application, you risk performance loss, premature failure, and higher wear and strain.

Identifying the kind of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Bearings are made to sustain three different types of loads: radial, thrust, and combination. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. Radial and thrust loads are combined to form combined loads.

The size of the bearings can help you focus your search once you've determined the kind of loads that will be placed on them. There are many different sizes of bearings, ranging from tiny bearings that can sustain light loads to big bearings that can support enormous loads.The size of the bearings you require will depend on the size of the shaft and the amount of load that will be placed on the bearings.

When selecting bearings for your application, it is important to consider the type of environment the bearings will be operating in. Bearings that will be exposed to wet or corrosive environments will need to be made from materials that can resist rust and corrosion.High speed operation will require that bearings be developed for high speed operation.Moreover, materials that can endure high temperatures must be used to create bearings that will be exposed to those temperatures.

Bearings come in a wide variety, with each type being created for a particular use or set of circumstances. Ball bearings, roller bearings, and sleeve bearings make up the three primary kinds.


Ball bearings are the most common type of bearing and can handle both radial and thrust loads.


They come in many different shapes and sizes, including:

-Angular contact
-Double row
-Four point
-Radial
-Self-aligning

There are numerous varieties of roller bearings, such as:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Bushings, also referred to as sleeve bearings, are utilized in a number of applications that call for rotation or linear motion.The following materials are accessible for them:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width are used to determine its size. The ID dimension defines the inner race bore size of the bearing, whereas the OD dimension determines the outer race size. The measurement that establishes the width of the bearing is its width.



  1. ball bearings - ID: 10 mm, OD: 30 mm, width: 9 mm

  2. roller bearings - ID: 20 mm, OD: 47 mm, width: 14 mm

  3. sleeve bearings - ID: 5 mm, OD: 10 mm, width: 4 mm



The ID, OD, and width of a bearing are all important factors to consider when selecting a bearing for a specific application.

The gap between the bearing races is maintained by balls in a ball bearing, a form of rolling-element bearing. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. At least two races are used to hold the balls and transport the weights through the balls in order to do this.
In most applications, one race is stationary and the other is attached to the rotating assembly. The rotating shafts of wheels were supported by ball bearings as early as in the, where they were first utilized.
Jules Suriray, Bearing1 a French bicycle mechanic, is credited with creating the ball bearing in 1869. In November of that year, he applied for a patent. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.
