Maintenance

  • TEF-MET®/P is a dry sliding bearing with a PTFE sliding layer. Lubrication is therefore not necessary. But it is suitable for lubricated applications (such as hydraulic oil lubrication).

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.
  • Stick-in: Adhesive should not contact the sliding surface
