19 knowledge to know types bearing

There are numerous types of bearings, each with particular advantages and disadvantages. The performance of a bearing is also influenced by its size. The different bearing types each have their own advantages and disadvantages. There are many different bearing types, each with unique benefits and drawbacks. 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. 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. Little, pointed needles are used in needle bearings to hold the shaft firmly in place. Thrust bearings are types of bearings that use flat plates known as races to hold a shaft in place.

The inner diameter (ID) and the outer diameter (OD) of a bearing determine its size (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 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 be spinning. 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.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 various types of bearings available on the market, each with their own advantages and disadvantages. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. 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. A set of balls that spin between inner and outer races make up these devices, which are commonly composed of steel or ceramic. For applications involving high speeds and/or weights, ball bearings are the best choice because they are relatively easy to use and long-lasting.

Similar to ball bearings, but made to support larger loads, are roller bearings. They are typically made from steel or brass and consist of a series of cylindrical rollers that rotate between inner and outer races. 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 enclosures that shield bearings from outside elements and give them a mounting point on a shaft or other support structure. There are many different sizes and types of bearing housings, which are commonly composed of steel or cast iron.

Self-contained, pre-assembled bearings known as bearing units are ready to be installed. Typically, they are made up 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.

In the design, research, production, and marketing of rolling bearings, plain bearings, and linear motion products, SKF is a global leader.


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 bearing actually moves around on the balls. The inner race is usually attached to the shaft that the bearing is supporting. Typically, the housing is fastened to the outside race.

Roller Bearings:


Ball bearings and roller bearings are quite similar, however the latter use cylinders in place of balls. Although roller bearings are able to carry greater weight than ball bearings, they are also more prone to break under heavy pressures.

Plain Bearings:



The most straightforward sort 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.

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 choosing the ideal bearings for your application is to determine the kinds of loads that will be placed on 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. Radial and thrust loads combine to form 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 required bearing size will depend on the dimensions of the shaft and the force that will be placed on the bearings.

The sort of environment the bearings will operate in should be taken 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 wet or corrosive conditions.Bearings that will be operating at high speeds will need to be designed for high speed operation.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 and set of circumstances. The three major groups are ball bearings, roller bearings, and sleeve bearings.


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


They are manufactured in a variety of sizes and designs, including:

-Angular contact
-Double row
-Four point
-Radial
-Self-aligning

The following types of roller bearings are available:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Bushings, also referred to as sleeve bearings, are utilized in a number of applications that call for rotation or linear motion.They come in a range of materials, such as:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width 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 determined by the 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 into account the bearing's ID, OD, and width.

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the bearing races apart. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. It does this by containing the balls in at least two races and transmitting 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.
French bicycle mechanic Jules Suriray 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.
