In 2021, imports and exports in the ball bearing industry increased by over 10% and over 32%, respectively. And that’s just one of the four main kinds of bearings.
Are you wondering what the other types of manufacturing bearings are, and which ones you should choose for your needs? With so many different types of bearings on the market, it can be hard to know which one is right for you.
Whether you’re looking for a ball bearing, roller bearing, or needle bearing, we have you covered. Keep reading as we’ve created a comprehensive guide to bearings that will help you understand the differences between each type.

Ball Bearings
Ball bearings are one of the best bearings and are found in nearly every type of machine. They are made up of several balls (usually around 7-10) that rotate around a stationary shaft.
This design allows for high speeds and low friction, making them ideal for applications where speed and efficiency are key.
Ball bearings are also relatively cheap and easy to maintain, making them a popular choice for many machines.
However, ball bearings are not as durable as some of the other types of bearings available and can be damaged if they experience too much stress or shock. They also require regular lubrication to keep them running smoothly.
Roller Bearings
Roller bearings are similar to ball bearings, in that they are made up of several small rolling elements. However, instead of balls, roller bearings use cylinders (called rollers) to reduce friction.
This design can handle more weight and stress than ball bearings, making them ideal for heavier duty applications. Roller bearings are also less likely to experience damage by shock or stress than ball bearings.
Sleeve Bearings
Sleeve bearings are a type of plain bearing, which means they do not use rolling elements to reduce friction. Instead, they rely on a smooth surface (usually metal) that slides against another smooth surface.
This design makes sleeve bearings much more resistant to shock and vibration than other types of bearings, making them ideal for applications where those factors are present.
Sleeve bearings also require less maintenance than rolling element bearings.
Spindle Bearings
Spindle bearings are a type of precision bearing. This means they design them for use in applications where accuracy and smoothness are critical.
They typically consist of two rows of balls or rollers that rotate around a stationary shaft. This design allows for high speeds and low friction, making them ideal for applications where accuracy is key.
Tapered Roller Bearings
Tapered roller bearings are a type of rolling-element bearing that uses tapered rollers to reduce friction. The rollers in a tapered roller bearing are cone-shaped, with the wider end facing the moving part of the bearing.
This design gives tapered roller bearings more stability and resistance to shock than other types of rolling element bearings.
Cam Followers Bearings
Cam followers bearings are a type of rolling-element bearing that uses cylindrical rollers to reduce friction. The rollers in an iCam follower bearing are parallel to the shaft, with the wider end facing the moving part of the bearing.
This design gives cam follower bearings more stability and resistance to shock than other types of rolling element bearings.
