BTW 100 CTN9/SP

Super-precision, basic design double direction angular contact thrust ball bearing

These double direction angular contact thrust ball bearings consist of two single row angular contact thrust ball bearings, arranged back-to-back.

They accommodate high axial loads in both directions and provide a high degree of system rigidity.

  • Accommodate axial loads in both directions
  • Maximum system rigidity
  • Separable
