Bearing loss for many reasons, all design and manufacturing process factors and bearing the loss related to analysis of them difficult to judge. 

SKF bearing installation, use, maintenance, maintenance, technical requirements, bear on the operation of the bearing load, speed, operating temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, be adjusted so that restore it to normal. Installation conditions is one of the primary factors bearing is often due to the installation of inappropriate stress state changes the entire bearing various parts, bearings operate in the normal state and an early termination of the life of internal factors bearing the three factors of quality refers to the structural design, manufacturing processes and materials, the quality of decisions.
1) Bearing design parameters: bearing the number of rolling bodies, the ferrule wall thickness, and clearance.
2) The error of the bearing parts manufacturing: including the bearing raceway and rolling element surface roughness, the transition pattern degrees and roundness difference. A large number of experimental studies have shown that the influence of the waviness of the bearing vibration is dominated by relatively small surface roughness and roundness.
3) Bearing the working conditions: the bearing during operation, load, speed, lubrication conditions, the three aspects of bearing vibration.
4) SKF bearing installation parameters: the bearing and shaft and bearing with the installation bias factors also bearing vibration impact.
