Insulated bearings

Ball and roller bearings with a special ceramic or PPS-resin coating are designed especially for industrial motors, generators, traction motors and wind energy applications.
These bearings have been developed to prevent electric pitting of the bearing.

The relationship between bearing temperature and insulation resistance of ceramic-insulated bearings was assessed and no deterioration of insulation resistance was observed up to 110°C. Even above 110°C, 100 MΩ of resistance was maintained.

Advantages of insulated bearings:

  • High precision
  • High temperature resistance
  • Low friction
  • Resistance to vibration
  • Electrically insulated
  • High reliability
  • Long operating life
Bearings with insulated coating are supplied in standard sizes, so there is no need for the bore to be specially prepared.
