SKF ANGULSKF CONTACT BALL BEARINGS, SUPER-PRECISION SKF 71924 ACEGA/P4A

This ultra-precision, high-speed E-design single row angular contact ball bearing can withstand both radial and axial loads acting in one direction. Designed to operate at high speeds, they have a slightly higher speed capacity and can withstand higher loads than SKF B-design high-speed bearings. Thanks to the universal mating match, the bearing can be mounted arbitrarily and the load can be evenly distributed between the two bearings within a pre-set preload range, without the need for spacers or similar devices.

  • 15° or 25° contact angle
  • Ultra-high running accuracy
  • It can withstand ultra-high speeds
  • Can be paired universally
