Spindle bearing rings

BALINIT C (WC/C) increases the pitting resistance of high speed spindle bearing rings. The coated raceways show no damage in comparison with uncoated bearing steel.

The advantages of BALINIT coated spindle bearings:

  • Sliding wear resistance against seal
  • Higher pitting resistance of bearing raceway
