Why MoS₂ Coating Is Used on Bearings for Magnetic Bearing Motors

MoS₂, or molybdenum disulfide, is a solid lubricant material used in various demanding mechanical applications.

For specialized magnetic bearing motor applications, MoS₂ coating can be applied to the inner and outer rings of bearings according to the equipment requirements.

Why Use MoS₂ Coating?

The coating can provide useful surface characteristics for applications where friction, wear and lubrication conditions need to be carefully controlled.

For high-speed precision bearings, the coating specification should be considered together with:

• Rotational speed
• Load conditions
• Operating temperature
• Lubrication
• Surface contact conditions
• Bearing clearance
• Required service life

Both deep groove ball bearings and angular contact ball bearings may be considered for specialized applications, depending on the motor design.

Beining Technology develops precision bearings for high-speed motors and specialized equipment. Our capabilities include deep groove ball bearings, angular contact bearings and customized bearing solutions.

For magnetic bearing motor applications, Beining can evaluate MoS₂ coating requirements for the inner and outer rings based on drawings and operating conditions.
