the radial basic dynamic load rating

Means a set of rolling taper roller bearing can withstand the constant imaginary radial loads, loads in the basic rating life of one million rpm. The single row angular contact bearings, this load causes the bearing rings to each other is purely radial displacement is generated between the radial component of the load.
8, the axial basic dynamic load rating

Refers to the hypothetical role of the center in a constant bearing axial load bearing loads in the basic rating life of one million rpm.
9, radial (or axial) equivalent dynamic load

Refers to a constant radial load (or central axial load), the load, the rolling bearing having the same load of the actual life.
10, radial (or axial) Basic static load rating

Means with a bearing manufacturer body raceways, and the total amount of permanent deformation corresponding radial static load (or the central axis of the static load). If at zero load, roller and raceway (roller bearing) is assumed to be normal or bus (line contacts) when the maximum contact stress, the rolling element and raceway contact produces a total permanent deformation of the rolling element diameter of 1/10000. For single row angular contact bearings, radial load rating of the bearing rings relative to each other due to pure radial displacement of the radial component of the load.
11, radial (or axial) Static equivalent load

The radial static load (or central axial static load) causes the maximum stress by rolling element and raceway contact at the total amount of permanent deformation resulting from the actual load conditions the same as the total amount of permanent deformation.
