Ultra-precision, high load carrying capacity single row angular contact ball bearings, 15° contact angle

These ultra-precision, high-load-capacity single-row angular contact ball bearings with a contact angle of 15° can withstand simultaneous radial and axial loads, whereas axial loads can only be applied in one direction. They are designed for low to medium operating temperatures, relatively high speeds and heavy loads.

  • 15° contact angle
  • Ultra-high running accuracy
  • High load carrying capacity
  • High speed and stiffness
