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, each created to address particular requirements and purposes. The top 4 bearing categories are as follows:



  • 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 place using tiny, hardened steel balls. The balls are positioned between two races, which are circular plates. Bearings that use cylindrical rollers rather than balls include roller bearings, which are also widely used. To hold the shaft in place, needle bearings use tiny, pointed needles. With the help of flat plates known as races, thrust bearings hold a shaft firmly in place.

The inner (ID) and outer (OD) diameters of a bearing define its size (OD). The bore, or the bearing's central hole, is measured by something called the ID. The measure of the outer race is called the OD. The bearing's width is calculated using the width.

Consider the load, speed, and vibration that the bearing will experience while selecting a bearing. The bearing must be able to support the load, which is the weight or force. The bearing will be spinning at a certain speed, which is the speed. The amount of movement the bearing will undergo is the vibration.

There are many different places to buy bearings. One choice is to get bearings from a nearby bearing supplier. Your purchasing of bearings from a bearings-specific website online is an additional choice.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 benefits and drawbacks of their own. The four most common types of bearings 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 prevalent kind of bearing is the ball bearing, which has a wide range of uses. They usually consist of a number of rotating balls that alternate between inner and outer races, and they are composed 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. They typically consist of a set of cylindrical rollers rotating between inner and outer races and are constructed of steel or brass. In applications where heavier loads are involved but speeds are not as high, roller bearings are more effective than ball bearings but are less long-lasting.

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 cast iron or steel.

Self-contained bearings that have been built and are prepared for installation are known as bearing units. A housing, a bearing, and a seal are often included. Since they come in a number of sizes and configurations, bearing units can be used in a wide range of applications.

Ball Bearings:


The most prevalent kind of bearings are ball bearings. They are comprised of a number of balls, two metal rings known as the inner and outer races, and the rings. 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. Typically, 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 can support higher loads than ball bearings, but they are also more likely to fail under high loads.

Plain Bearings:



Plain bearings are the simplest type of bearing. They are made from two metal surfaces that slide against each other. To lessen wear and friction, plain bearings can be greased with oil or grease.

Bearing types and sizes are very important factors to consider when selecting the right bearings for your application. There are many different types of bearings available on the market, and each type has its own unique set of benefits and drawbacks. Selecting the wrong type of bearing for your application can result in increased wear and tear, reduced performance, and even premature 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 mixed loads are the three main types of loads that bearings are made to withstand. Thrust loads are delivered parallel to the shaft, while radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.

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

It is crucial to take into account the sort of environment the bearings will be working in when choosing bearings for your application. Bearings that will be exposed to wet or corrosive environments will need to be made from materials that can resist rust and corrosion.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 in the construction of bearings that will be exposed to them.

There are many different types of bearings, each designed for specific applications and operating conditions. The three major categories are sleeve bearings, ball bearings, and roller 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, such as:

-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, also known as bushings, are used in a wide variety of applications requiring rotation or linear motion.The following materials are accessible for them:

-Bronze
-Babbitt
-Plastic

The inner diameter (ID), outer diameter (OD), and width of a bearing 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 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 into account the bearing's ID, OD, and width.

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 Bearing1.eu support radial and axial loads. 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. 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. In November of that year, he applied for a patent. German engineer Friedrich Fischer created the first industrial ball bearings in 1883.
