There are numerous types of bearings, each with particular advantages and disadvantages. A bearing's performance is also impacted by its size. Every type of bearing has advantages and cons of its own. There are many different bearing types, each with unique benefits and drawbacks. The many bearing types that are available, as well as their benefits and drawbacks, will be covered in this article. We'll also go over how to choose the ideal bearing size for your requirements.

Bearing Types



There are many types of bearings, each designed to meet specific needs and applications. There are 4 primary categories of bearings:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


Ball bearings are the most common type of bearing and can be found in a wide range of machinery and equipment. These are bearings that hold the shaft in position using tiny, hardened steel balls. 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. The shaft is held in position by tiny, pointed needles in needle bearings. Thrust bearings are bearings that keep a shaft in place by using flat plates called races.

Inner diameter (ID) and outer diameter (OD) together determine a bearing's size (OD). The bore, or the hole in the center of the bearing, is measured by a number called the ID. The measure of the outer race is called the OD. The width is a measurement of the bearing's width.

It is crucial to take into account the load, speed, and vibration that the bearing will experience while selecting one. The bearing's required capacity to support a given weight or force is known as the load. The speed is the rate at which the bearing will spin. The vibration is the amount of movement that the bearing will experience.

Bearings can be purchased in a variety of locations. One option is to purchase bearings from a local bearing supplier. Another choice is to buy bearings from a bearings-specific website online.Several bearings-selling websites additionally offer a web-based quote system that enables you to get a price for the bearings you require.

There are numerous types of bearings on the market, each with unique benefits and drawbacks. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Each type of bearing has its own unique set of characteristics that make it more or less suited for certain applications.

The most popular form of bearing and its many applications are ball bearings. They typically consist of a set of balls that spin between inner and outer races and are constructed of steel or ceramic. Ball bearings are perfect for applications involving high speeds and/or loads since they are reasonably easy to use and long-lasting.

Similar to ball bearings, but made to support larger loads, are roller bearings. Usually made of steel or brass, they are composed of a number of cylindrical rollers that alternately rotate between inner and outer races. Roller bearings are more efficient than ball bearings but are not as durable, making them suitable for applications where higher loads are involved but speeds are not as high.

Bearing housings are enclosures that protect bearings from contaminants and provide a way to mount them onto a shaft or other support structure. Bearing housings are typically made from cast iron or steel and are available in a variety of sizes and shapes.

Self-contained bearings that have been pre-assembled and are prepared for installation are known as bearing units. They typically consist of a housing, a bearing, and a seal. 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 are made from two metal rings, called the inner and outer races, and a group of balls. The real rolling surface of the bearing is 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:


Ball bearings and roller bearings are extremely similar, however roller bearings use cylinders in place of balls. Compared to ball bearings, roller bearings can withstand larger loads, but they are also more prone to failure when subjected to heavy loads.

Plain Bearings:



Plain bearings are the simplest type of bearing. They're constructed from two sliding metal surfaces. Plain bearings can be lubricated with oil or grease to reduce friction and wear.

Selecting the best bearings for your application requires careful consideration of bearing types and sizes. There are numerous varieties of bearings on the market, and each type has an own set of advantages and disadvantages. If you choose the improper kind of bearing for your application, you risk performance loss, premature failure, and higher wear and strain.

Understanding the types of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Radial, thrust, and mixed loads are the three main types of loads that bearings are made to withstand. Radial loads are applied perpendicular to the shaft, while thrust loads are applied in a parallel direction. 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 required bearing size will depend on the dimensions of the shaft and the force that will be placed on the bearings.

It is crucial to take into account the sort of environment the bearings will be working in when choosing bearings for your application. Rust- and corrosion-resistant materials must be used to create bearings that will be used in wet or corrosive conditions.High speed operation will require specially developed bearings for use at those speeds.And materials that can endure high temperatures must be used to create bearings that will be exposed to those temperatures.

There are numerous varieties of bearings, each of which is created for a particular use and set of circumstances. Ball bearings, roller bearings, and sleeve bearings make up the three primary kinds.


The most prevalent bearings are ball bearings, which can support both thrust and radial stresses.


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

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

The following types of roller bearings are available:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Many different applications that call for rotational or linear motion require sleeve bearings, also known as bushings.They are available in a variety of materials, including:

-Bronze
-Babbitt
-Plastic

The inner diameter (ID), outer diameter (OD), and width of a bearing 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.

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the distance between the bearing races constant. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
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, a French bicycle mechanic, is credited with creating the ball bearing in 1869. In November of that year, he applied for a patent. German engineer Friedrich Fischer created the initial ball bearings for commercial use in 1883.
