SKF ANGULSKF CONTACT BALL BEARINGS, SUPER-PRECISION SKF 71901 CE/P4A

This ultra-precision, high-speed E-design, single row angular contact ball bearing with a 15° contact angle can accommodate both radial and axial loads acting in one direction. Designed to withstand very high speeds. Compared to the same SKF B-design high-speed bearings, they have a slightly higher speed capacity and can withstand higher loads.

  • 15° contact angle
  • Ultra-high running accuracy
  • It can withstand ultra-high speeds
  • It can withstand high radial loads and large unidirectional axial loads
