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 pick the ideal bearing size for your requirements.

Bearing Types



There are numerous bearing kinds, and each is made to serve a certain purpose. The four primary categories of bearings are:



  • 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. Roller bearings are also a common type of bearing and use cylindrical rollers instead of balls. To hold the shaft in place, needle bearings use tiny, pointed needles. Thrust bearings are bearings that keep a shaft in place by using flat plates called races.

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 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 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 endure is the vibration.

Bearings can be purchased in many different locations. One choice is to get bearings from a neighborhood bearing supplier. A different choice is to buy bearings from a bearings-specific website online.You can get a quote for the bearings you need from some bearings-selling websites using their web-based quoting system.

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

The most prevalent kind of bearing is the ball bearing, which has a wide range of uses. 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 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. They typically consist of a set of cylindrical rollers rotating between inner and outer races and are constructed of steel or brass. 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 shield bearings from outside elements 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 cast iron or steel.

Self-contained bearings that have already been put together and are ready for installation are known as bearing units. In most cases, they are made up 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 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 actually moves around on the balls. Typically, the inner race is fastened to the shaft the bearing is supporting. Typically, the housing is fastened to the outside race.

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. They are made from two metal surfaces that slide against each other. To alleviate wear and friction, grease or oil can be applied to plain bearings.

Bearing types and sizes are very important factors to consider when selecting the right bearings for your application. There are numerous varieties of bearings on the market, and each type has an own set of advantages and disadvantages. Inappropriate bearing selection can lead to increased wear and tear, decreased performance, and even early failure.

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. Whereas thrust loads are provided in a parallel direction, radial loads are applied perpendicular to the shaft. Together, radial and thrust loads make up combined loads.

Once you have identified the type of loads that will be applied to the bearings, you can narrow down your options by considering the size of the bearings. From small bearings that can sustain light weights to huge bearings that can support enormous loads, bearings come in a variety of sizes.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. Materials that can resist rust and corrosion must be used to create bearings that will be exposed to moist or corrosive conditions.High speed operation will require that bearings be developed 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.

Bearings come in a variety of forms, each of which is created for particular uses and operational circumstances. Ball bearings, roller bearings, and sleeve bearings make up the three primary kinds.


The most prevalent bearings are ball bearings, which can withstand both thrust and radial loads.


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, also known as bushings, are used in a wide variety of applications requiring rotation or linear motion.They are available in a variety of materials, including:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width all contribute to 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 width is the dimension that determines the bearing's 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



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

A ball bearing is more info 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. 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. The rotating shafts of wheels were supported by ball bearings in an early application of this technology in the.
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.
