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, 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. The balls are positioned between two races, which are circular plates. Another typical type of bearing uses cylindrical rollers rather than balls; these are known as roller bearings. Needle bearings are bearings that use small, sharp needles to keep the shaft in place. With the help of flat plates known as races, thrust bearings hold a shaft firmly in place.

The inner diameter (ID) and outer diameter (OD) of a bearing determine its size (OD). The bore, or the bearing's central hole, is measured by something called the ID. The OD is the measurement of the outer race. The width is a measurement of the bearing's width.

Consider the load, speed, and vibration that the bearing will experience while selecting a bearing. The load is the weight or force that the bearing will need to support. The bearing's speed is the rate at which it will spin. The vibration indicates how much movement the bearing will undergo.

Bearings can be purchased in a variety of locations. One choice is to get bearings from a nearby bearing supplier. Another option is to purchase bearings online from a website that specializes in bearings.You can get a quote for the bearings you need from several bearing-selling companies using their web-based quoting system.

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. 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 the one that is utilized in the most applications is the ball bearing. A set of balls that spin between inner and outer races make up these devices, which are commonly 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.

Roller bearings are similar to ball bearings but are designed to carry heavier loads. They are typically made from steel or brass and consist of a series of cylindrical rollers that rotate between inner and outer races. In applications where heavier weights are present but speeds are not as high, roller bearings work better than ball bearings but are less robust.

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 come in a variety of sizes and shapes and are commonly composed of cast iron or steel.

Self-contained, pre-assembled bearings known as bearing units are ready to be installed. They typically consist of a housing, a bearing, and a seal. A wide range of applications can be accommodated by the availability of bearing units in a variety of sizes and configurations.

Rolling bearings, plain bearings, and components for linear motion are all created, developed, produced, and marketed by SKF, a global leader in these industries.


Ball Bearings:


The most popular 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 that the bearing is supporting. Typically, the outer race is fastened to the housing.

Roller Bearings:


Comparable to ball bearings in many ways, roller bearings use cylinders as opposed to 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:



The simplest kind of bearings are plain bearings. They are made from two metal surfaces that slide against each other. 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 many different types of bearings available on the market, and each type has its own unique set of benefits and drawbacks. If the wrong kind of bearing is chosen for your application, it may lead to greater wear and tear, decreased performance, or even early 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. There are three primary types of loads that bearings are designed to support: radial, thrust, and combined. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to the shaft. 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 shaft's diameter and the amount of load that will be placed on the bearings will determine the size of bearings you require.

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.Furthermore, materials that can endure high temperatures must be used to create bearings that will be exposed to them.

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 major kinds.


The most typical bearing is a ball bearing, which can support both thrust and radial stresses.


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, commonly referred to as bushings, are employed in a number of applications that call for rotation or linear motion.They come in a range of materials, such as:

-Bronze
-Babbitt
-Plastic

The inner diameter (ID), outer diameter (OD), and width of a bearing are used to determine its size. 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, the ID, OD, and width of the bearing are all crucial considerations.

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. An early application of the ball bearing was in the, where they were used to support the rotating shafts of wheels.
French bicycle mechanic Jules Suriray is credited with developing the ball bearing in 1869. In November of that year, he submitted a patent application. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
