SKF ANGULSKF CONTACT BALL BEARINGS, SUPER-PRECISION SKF 7022 CDGA/P4A

This ultra-precision, high-capacity, single-row angular contact ball bearing can withstand both radial and axial loads acting simultaneously, while axial loads can only act in one direction. Designed for low to medium operating temperatures, relatively high speeds and heavy loads. Thanks to the universal mating, the bearings can be mounted arbitrarily and can be evenly distributed between the two bearings within a pre-set preload range without the use of gaskets or similar devices.

  • 15° or 25° contact angle
  • Ultra-high running accuracy
  • Ultra-high load carrying capacity
  • Higher rotational speed and stiffness
  • Can be paired universally
