We'll talk about the many types of bearings that are available in this post, along with their benefits and drawbacks. Furthermore, we'll describe how to choose the ideal bearing size for your requirements.

Bearing Types



There are numerous bearing kinds, each created to address particular requirements and purposes. 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, and these can be found in a variety of machines and equipment. Little, hardened steel balls are used in these bearings to hold the shaft in place. Between two circular plates known as races are the balls. Another typical type of bearing is the roller bearing, which substitutes cylindrical rollers for 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 measurement of the outer race is the OD. The bearing's width is calculated using the 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 amount of movement the bearing will undergo is the vibration.

Bearings can be purchased in numerous locations. A local bearing supplier is one choice for where to get bearings. A different 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 many different types of bearings on the market, and each has pros and disadvantages of their own. The four most common types of bearings are ball bearings, roller bearings, bearing housings, and bearing units. Every type of bearing has a special set of qualities that make it more or less suitable for particular applications.

The most prevalent kind of bearing is the ball bearing, which has a wide range of uses. 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.

Although identical to ball bearings, roller bearings are made to support greater loads. A series of cylindrical rollers that rotate between inner and outer races make up these devices, which are commonly composed 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.

Bearing units are self-contained bearings that are pre-assembled and ready to be installed. Usually, a housing, a bearing, and a seal make up these devices. Because they come in a number of sizes and configurations, bearing units can be used in a wide range of applications.

Ball Bearings:


The most typical bearing type is a ball bearing. They consist of a number of balls and two metal rings known as the inner and outer races. The real rolling surface of the bearing is the balls. The shaft that the bearing is supporting normally has the inner race linked to it. The outer race is usually attached to the housing.

Roller Bearings:


In contrast to ball bearings, which employ balls, roller bearings use cylinders. Roller bearings can support higher loads than ball bearings, but they are also more likely to fail under high loads.

Plain Bearings:



The simplest kind of bearings are plain bearings. Two metal surfaces that slide against one another are used to create them. Oil or grease can be used to lubricate plain bearings to lessen wear and friction.

When choosing the correct bearings for your application, bearing types and sizes are crucial considerations. There are numerous varieties of bearings on the market, and each type has a distinct set of advantages and disadvantages.The market offers a wide variety of bearing types, and each kind 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.

Identifying the kinds of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Radial, thrust, and combined loads are the three main types of loads that bearings are intended to withstand. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. Together, radial and thrust loads make up combined loads.

Once you've determined the kinds of loads that will be placed on the bearings, you may focus your search by taking the bearings' sizes into account. Bearings are available in a wide range of sizes, from small bearings that can support light loads to large bearings that can support heavy 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. It is necessary to use materials that can resist rust and corrosion when creating bearings that will be used in wet or corrosive settings.High speed operation will require specially developed bearings for use at those speeds.Furthermore, materials that can endure high temperatures must be used to create bearings that will be exposed to them.

Bearings come in a wide variety, with each type being created for a particular use or set of circumstances. The three main categories are ball bearings, roller bearings, and sleeve bearings.


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


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

Sleeve bearings, commonly referred to as bushings, are utilized in a number of applications where rotation or linear motion is necessary.They come in a range of materials, such as:

-Bronze
-Babbitt
-Plastic

The size of a bearing is measured by its inner diameter (ID), outer diameter (OD), and width. The bearing's inner race bore size is determined by the ID, but the outer race size is determined by the OD. The bearing's breadth is decided by its width, which is 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 the bearing's ID, OD, and breadth into account.

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. 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.
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.
Jules Suriray, a French bicycle mechanic, is credited with developing the ball bearing in 1869. That year, in November, he submitted a patent application. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
