SKF ANGULSKF CONTACT BALL BEARINGS, SUPER-PRECISION SKF 7024 ACE/P4A

This ultra-precision, high-speed E-design single-row angular contact ball bearing can withstand both radial and axial loads in one direction. Designed to withstand high speeds. It has a slightly higher speed capability and can withstand higher loads than the same SKF B-design high-speed bearings.

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