1 life
Means a set of bearings, wherein a ferrule (or washer) or rolling of the material before the first signs of fatigue extension, a ferrule (or washer) relative to the other ferrule of the number of revolutions (or washer).
2, reliability (i.e., the reliability of the bearing life)
Refers to a group of operating under the same conditions, nearly the same Rolling desired reaches or exceeds a predetermined percentage life of. The reliability of a single Rolling bearing reaches or exceeds a predetermined probability of life.
3, static load
When the relative rotational speed of the bearing rings or washers is zero (to the heart or thrust bearings) or when the raceway element is no motion in the rolling direction (linear bearings), acting on the load on the bearings.
4, dynamic and static charge
When the bearing rings or washers relative rotation (to the heart or thrust bearings) or when the rolling element linear bearings in the rolling direction (a) acting on the load on the bearings.
5, rated life
Basic dynamic radial load or axial basic dynamic load rating based on the life of predictive value.
6, the basic rating life
Rated life associated with 90% reliability.
7, radial basic dynamic load rating
Refers to a set of rolling bearings is supposedly able to withstand constant radial load, this loads the basic rating life of one million revolutions. For a single-row angular contact bearing, the load is caused by the bearing rings between the load of the radial component of the pure radial displacement.
8, the basic dynamic axial load
Hypothetical role at the center of the rolling bearing constant axial load and basic rating life of rolling bearings in the loads of one million turn.
9 radial (or axial) equivalent dynamic load
Refers to a constant radial load (or central axial load) in under the load, the rolling bearing having the same life and actual loads.
10 radial (or axial) basic static load rating
Means rolling elements and the raceways of the total permanent deformation corresponding radial static load (or central axial static load). If at zero load, the roller and the raceway (roller bearings) or assumed as normal bus (all contacts), the maximum contact stress, the rolling elements and raceway contact generated at the total amount of permanent deformation of the rolling elements a diameter of 1/10000. Single row angular contact bearings, radial load rating as the cause of the radial component of the load bearing rings relative to each other purely radial displacement.
11, radial (or axial) equivalent static load
The radial static load (or center axial static load) make by the total permanent deformation of the rolling element and raceway contact at maximum stress generated total permanent deformation of the actual load conditions.
