NSK QJ Four-Point Contact Ball Bearings (QJ2, QJ3, QJ10)

NSK QJ Four-Point Contact Ball Bearings (QJ2, QJ3, QJ10)

NSK QJ series four-point contact ball bearings, bore 30-200 mm, with a split inner ring that allows axial loads in both directions in a single bearing.

Key features

  • Two-piece inner ring gives four-point ball contact
  • Carries axial loads in both directions within one bearing
  • Space-saving alternative to paired angular contact bearings
  • Ratings given as axial dynamic Ca and static C0a
