Key Factors Affecting Bearing Performance at High Speed

High-speed applications place demanding requirements on precision bearings. For magnetic bearing motors, bearing performance depends on the interaction between the bearing and the complete motor system.

Bearing Type

Deep groove ball bearings and angular contact bearings have different load characteristics. Selection should match the actual operating requirements.

Preload and Clearance

Preload and internal clearance can influence friction, rigidity, temperature and running stability. The appropriate condition depends on speed, load and installation.

Lubrication

Lubrication helps control friction and heat. The lubricant and lubrication method should be selected according to operating speed and temperature.

Bearing Precision

Small variations in bearing geometry can affect high-speed running performance. Dimensional accuracy and running accuracy should be considered.

Temperature

Heat generation can affect lubricant performance and internal bearing conditions. Thermal behavior should therefore be evaluated together with speed and preload.

MoS₂ Coating

For specialized applications, MoS₂ coating on the inner and outer rings can be considered according to friction, wear and operating requirements.
