1. Starting torque
So that a bearing rings or washer with respect to another fixed rings or washer starts to rotate the desired torque.
2 rotational torque
When the when a bearing rin gs or washers rotation, prevents to another ferrule or washers movement the torque required.ball bearing company
3. Radial load
Acting on the load in the direction perpendicular to the bearing axis line.
4. Axial load
Acting on a load parallel to the direction of the bearing axis line.
Static load.
When zero relative rotational speed of the bearing rings or washers (to the heart or thrust bearings), or when no movement of the rolling element in the rolling direction (linear bearings), the load acting on the bearing.
6 dynamic load
When the bearing rings or washers relative rotation (to the heart or thrust bearings) or linear bearings), the load acting on the bearing rolling element in the rolling direction (.
7. Equivalent load
The general term used to calculate the theoretical load, in certain situations, the bearings in the theory under load match withstand the actual load.
Radial (axial) Basic static the the load basic static radial (axial) load ratingdouble bearing
Corresponding with the rolling elements and the raceways the total amount of permanent deformation of the radial load (the central axial load). If zero load roller and the raceway (roller bearings), or assume that for the normal bus (full line contact), maximum contact stress total permanent deformation of the rolling element and raceway contact at the rolling body 0.0001 times the diameter. Single row angular contact bearings, radial load rating to cause bearing rings relative to each other pure radial displacement of the radial component of the load.
Radial (axial) basic dynamic load rating
Constant radial load (the center of the axial load constant), under the load, the Rolling theoretically may be subjected to the basic rated life of 1 million revolutions. Single row angular c ontact bearings, the radial load rating caused the bearing rings relative to each other purely radial displacement of the load component.
10 (referring to a set of bearings life)
Bearing a ferrule or a washer or a rolling the material of the first occurrence of fatigue extension before a ferrule or a washer with respect to another ferrule or the number of revolutions of a washer. The number of operating hours of the life can also be used in a given constant speed to represent.
11 Reliability (refers to bearing life)
The operation under the same conditions, a group of nearly the same Rolling expected to reach or exceed a specified life of the bearing percentage. The reliability of a set of bearings for this bearing reaches or exceeds a predetermined probability of life.
12 rated life
The radial basic dynamic load or axial basic dynamic load rating is based on the life of the predicted value.
13 basic rating life
Rated life associated wi th 90% reliability.
14 life factor
In order to get dynamic load with dynamic load corresponding to a fixed set life rated radial or Basic axial correction factor applied to the equivalent dynamic load.
15 seat belt bearing
Radial bearings and seat combination with an assembly for the mounting screws in the supporting surface in parallel with the bearing axis line backplane.
16 Vertical Block
Loaded rolling bearings with a seat.
