The torque required to rotate a bearing ring or washer relative to the opening of another fixed ferrule or washer.
2. Rotational torque
When a bearing ring or washer rotates; the torque required to block the movement of the other ring or washer.
3. Radial load
The effect is the load in the direction of the axial direction of the straight bearing.
4. Axial load
The effect is the load in the direction of the axis of the parallel bearing shaft.
5. 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 direction of rolling (linear bearing); the effect on the bearing.
6. Dynamic load
When the bearing ring or washer is relatively rotated (central or thrust bearing) or when the tumble element is moving in the direction of rolling (linear bearing); the effect on the bearing.
7. Equivalent load
The general term used to account for theoretical loads; in certain situations; the bearing appears to bear the practical load under the theoretical loading effect.
8. Radial (axial) fundamental static static (axial) load rating
Radial static load (intermediate axial static load) corresponding to the total eternal deformation of the roll and raceway. If under zero load; roller and raceway (roller bearing) are or assumed to be normal busbars (full line When touched; under the maximum touch stress; the total eternal deformation occurring at the roll and raceway touch is 0. 0001 times the diameter of the roll body. For single row angular touch bearings; the radial extra load is such that the bearing rings are opposite each other. The radial weight of the load with pure radial displacement.
9. Radial (axial) fundamental dynamic load (axial) load rating
Stable radial load (stable intermediate axial load); under this load; the rolling bearing can theoretically saturate the fundamental extra life of 1 million rpm. For single-row angular touch bearings; the radial additional load is the resulting bearing sleeve The weight of the load relative to each other with a pure radial displacement.
10. Life (refers to a set of bearings) life
The number of revolutions of a ferrule or a washer or a tumbling element of the bearing is initially shown before the fatigue is enlarged; the number of revolutions of one ferrule or one washer relative to the other ferrule or a washer. The life is also available at a given steady speed. Working hours to indicate.
11. Reliability (referring to the bearing life)
A group of nearly identical rolling bearings operating under the same conditions. The percentage of bearings that wish to reach or exceed a certain number of lifespans. The reliability of a set of bearings is the probability that the bearing will reach or exceed the ruled life.
12. Extra life rating life
The guess value of the lifespan based on the radial fundamental extra dynamic load or the axial fundamental extra dynamic load.
