Ultra-precision, high load carrying capacity universal paired single row angular contact ball bearings

These ultra-precision high load carrying capacity single row angular contact ball bearings can withstand simultaneous radial and axial loads, while the axial load can only act in one direction. They are designed for low to medium operating temperatures, relatively high speeds and heavy loads. Due to the universal pairing, the bearings can be mounted in any position, allowing an even distribution of load between the two bearings within a pre-set preload range without the use of shims or similar devices.

  • 15° or 25° contact angle
  • High running accuracy
  • High load carrying capacity
  • High speed and stiffness
  • Universal mating
