Starting torque
The torque required to initiate rotation of a bearing ring or washer relative to another fixed ferrule or washer.
Rotational torque
When a bearing ring or washer rotates, the torque required to move the other ring or washer is prevented.
Radial load
The load acting on the axis of the vertical bearing axis.
4. axial load
A load acting in the direction of the axis of the parallel bearing.
Static load
When the relative rotational speed of the bearing ring or washer is zero (central or thrust bearing) or when the rolling element does not move in the rolling direction (linear bearing), the load acting on the bearing.
Dynamic load
The load acting on the bearing when the bearing ring or washer is relatively rotated (central or thrust bearing) or when the rolling element is moving in the rolling direction (linear bearing).
7. equivalent load equivalent load
The general term used to calculate the theoretical load. In a particular case, the bearing is subjected to the actual load under the theoretical load.
8. Radial (axial) basic static static load (axial) load rating
Radial static load (central axial static load) corresponding to the total permanent deformation of the rolling elements and raceways. If the roller and the raceway (roller bearing) are or assumed to be normal busbars (full line contact) under zero load, the total permanent deformation generated at the contact between the rolling element and the raceway is the rolling element under the maximum contact stress. 0.0001 times the diameter. For single row angular contact bearings, the radial load rating is the radial component of the load that causes the bearing rings to be relatively purely radially displaced from each other.
9. Radial (axial) basic dynamic load (axial) dynamic rating
Constant radial load (constant central axial load) under which the rolling bearing can theoretically withstand a basic rating life of 1 million revolutions. For a single row of angular contact bearings, the radial load rating is a component of the load that causes the bearing rings to be relatively purely radially displaced from one another.

The life can also be expressed as the number of hours of operation at a given constant speed.
11. Reliability (referring to bearing life) reliability
The percentage of bearings that are operating under the same conditions that are near the same rolling bearing that are expected to meet or exceed a specified life. The reliability of a set of bearings is the probability that the bearing will reach or exceed the specified life.
12. Rating life rating life
