14 info to know types bearing

There are different bearing kinds, and each has 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, and each has unique benefits and drawbacks. We'll talk about the many types of bearings that are available in this post, along with their benefits and drawbacks. 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 four primary categories of bearings 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. The shaft is held in position by these bearings, which use tiny, hardened steel balls. 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. Little, pointed needles are used in needle bearings to hold the shaft firmly 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 vibration is the amount of movement that the bearing will experience.

Bearings can be purchased in a variety of places. One choice is to get bearings from a neighborhood bearing supplier. A different choice is to buy bearings from a bearings-specific website online.Some websites that sell bearings also offer a web-based quoting system that can provide you with a quote for the bearings that you need.

There are numerous types of bearings on the market, each with unique benefits and drawbacks. 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 its many applications are ball bearings. They are typically made from steel or ceramic and consist of a series of balls that rotate between inner and outer races. 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.

Bearing units are self-contained bearings that are pre-assembled and ready to be installed. 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 popular type of bearing is a ball bearing. They are made from two metal rings, called the inner and outer races, and a group of balls. The bearing really rolls on 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 most basic sort of bearings are plain bearings. They're constructed from 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. Whereas thrust loads are provided in a parallel direction, radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.

Consider the size of the bearings to reduce your alternatives after determining the types 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 want will depend on the diameter of the shaft and the force that will be placed on them.

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 used in wet or corrosive conditions.High speed operation will require specially developed bearings for use at those speeds.And bearings that will be subject to high temperatures will need to be made from materials that can withstand high 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, including:

-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. The ID is the dimension that determines the bearing's inner race bore size, while the OD is the dimension that determines the size of the bearing's outer 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 the bearing's ID, OD, and breadth into account.

The gap between the bearing races is maintained by balls in a ball bearing, a form of rolling-element bearing. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. 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, a French bicycle mechanic, is credited with creating the ball bearing in 1869. He filed a patent in November of that year. In 1883, German engineer Friedrich Fischer created the first ball bearings used in commerce.

With bearings, two surfaces can move smoothly and with less friction against one another. Little metal balls are used in ball bearings to lower friction, hence the name "ball bearing" is a misnomer. Between two races, or rings, the balls are positioned, and they rotate as the inner ring revolves.

The automotive, aerospace, and industrial industries all employ ball bearings in a number of ways. Roller skates, bicycles, and fans are just a few examples of the equipment that uses them.Depending on the purpose, there are many different sizes and types of ball bearings.
