Tolerance details

  • Housing Ø H7
  • Shaft tolerance Specified by the customer

Shaft Material

  • Hardened steel (C45 recommended)

Mounting advise

  • Housing: Mounting bevel min. 1.5 mm x 15-45°
  • Shaft: Mounting bevel 5 mm x 15°, edges rounded
  • The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.


  • Sufficient lubrication is necessary!


** The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions, eg. higher sliding speed or strain, these values are subject to change.
*** No stock of this bearing type, all sizes will be produced order related.
