In this article, we'll discuss the different types of bearings available, as well as their pros and cons. We'll also go over how to choose the ideal bearing size for your requirements.

Bearing Types



There are numerous bearing kinds, and each is made to serve a certain purpose. The 4 main types of bearings are:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


The most prevalent type of bearing is a ball bearing, which is used in a variety of tools and machines. The shaft is held in position by these bearings, which use tiny, hardened steel balls. The balls are positioned between two races, which are circular plates. Another frequent type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. Needle bearings are bearings that use small, sharp needles to keep the shaft in place. With the help of flat plates known as races, thrust bearings hold a shaft firmly in place.

The size of a bearing is determined by the inner diameter (ID) and the outer diameter (OD). The diameter (ID) of the bore, or the hole in the center of the bearing, is its measurement. The measure of the outer race is called the OD. The breadth of the bearing is measured by the width.

It is crucial to take into account the load, speed, and vibration that the bearing will experience while selecting one. The bearing must be able to support the load, which is the weight or force. The bearing will be spinning at the specified speed. The amount of movement the bearing will endure is the vibration.

There are many different places to buy bearings. One option is to purchase bearings from a local bearing supplier. Another option is to purchase bearings online from a website that specializes in bearings.Several bearings-selling websites additionally offer a web-based quote system that enables you to get a price for the bearings you require.

On the market, there are numerous bearing kinds, each with advantages and drawbacks of their own. The four most typical types of bearings are ball bearings, roller bearings, bearing housings, and bearing units. Each kind of bearing has a distinct set of qualities that make it more or less appropriate 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.

Bearing housings are enclosing devices that shield bearings from impurities and give them a mounting point on a shaft or other support structure. Bearing housings come in a variety of sizes and shapes and are commonly composed of steel or cast iron.

Self-contained bearings that have been pre-assembled and are prepared 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.

Ball Bearings:


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

Roller Bearings:


In contrast to ball bearings, which employ balls, roller bearings use cylinders. Roller bearings are more likely to break under heavy loads even if they can sustain larger loads than ball bearings.

Plain Bearings:



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

When choosing the best bearings for your application, bearing types and sizes are crucial considerations. There are numerous varieties of bearings on the market, and each type has an own set of advantages and disadvantages. If the wrong kind of bearing is chosen for your application, it may lead to greater wear and tear, decreased performance, or even early failure.

The first step in selecting the right bearings for your application is to identify the type of loads that will be applied to the bearings. Radial, thrust, and combined loads are the three main types of loads that bearings are intended to withstand. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.

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 shaft's diameter and the amount of load that will be placed on the bearings will determine the size of bearings you require.

It's critical to take the operating environment into account when choosing bearings for your application. Rust- and corrosion-resistant materials must be used to create bearings that will be more info used in wet or corrosive conditions.Bearings that will be operating at high speeds will need to be designed for high speed operation.Moreover, materials that can endure high temperatures must be used to create bearings that will be exposed to those temperatures.

There are many different types of bearings, each designed for specific applications and operating conditions. Ball bearings, roller bearings, and sleeve bearings make up the three major kinds.


The most typical bearing is a ball bearing, which can support both thrust and radial stresses.


They are produced in a range of shapes and sizes, such as:

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

Roller bearings are available in several different types, including:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Sleeve bearings, commonly referred to as bushings, are employed in a number of applications that call for rotation or linear motion.They come in a range of materials, such as:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width are used to determine its size. Whereas the OD determines the size of the bearing's outer race, the ID is the parameter that determines the bore size of the bearing's inner race. The bearing's breadth is determined by the width as a dimension.



  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



When choosing a bearing for a particular application, it's crucial to take into account the bearing's ID, OD, and width.

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the bearing races apart. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. In order to contain the balls and transport the stresses via the balls, at least two races are used.
Typically, one race is attached to the rotating assembly, and the other is immobile, depending on the application. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
French bicycle mechanic Jules Suriray is credited with developing the ball bearing in 1869. In November of that year, he submitted a patent application. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
