|A bearing is composed of inner ring, outer ring, rolling element and cage that are usually called four parts.
In a sealed bearings there are additional lubricant and sealing part that added above four parts are usually called six parts.
|A bearing can bear an appropriate radial or/and axial load and rotate at a limited aped.|
|A bearing with different precision has different rotating accuracy.|
|When the bearing is working (rotating at a constant speed), it has the capability to withstand the radial and axial load.
Selecting different bearings according to working conditions can exert bearing function and extend the life of bearing.
