What is the difference between a rolling bearing and a roller bearing? Who knows?

Roller bearing: one of the components widely used in modern machinery.

2. Ball bearing: a kind of rolling bearing. The ball bearing is installed between the inner steel ring and the outer steel ring, which can bear a large load.

Second, the principle is different.

1. ball bearing: determine the relative position of two components (usually shaft and bearing seat) to ensure that they can rotate freely while transmitting load. At high speed (for example, in gyro ball bearings), this application can be extended to include free rotation, and the bearing has little wear.

2. Roller bearing: supporting rotating parts through rolling contact. Different rolling bearings can bear different radial and axial forces. When selecting rolling bearings, they should be selected according to specific working conditions.

Extended data:

Ball bearings are used for rotating parts of various machines and equipment. Designers usually have to decide whether to use ball bearings or liquid film bearings in specific applications. In many cases, the following features make ball bearings more popular than liquid film bearings.

1, the starting friction is small and the working friction is appropriate.

2. It can bear radial and axial loads.

3, insensitive to lubrication interruption.

4. No self-excited instability.

5. It is easy to start at low temperature.
