TOLERANCE DETAILS

  • Housing Ø H7
  • Bushing inner-Ø after mounting H9
  • Shaft tolerance f7 to h8

SHAFT MATERIAL

  • Steel, hardened or untempered, surface roughness ≤ Rz 2-3

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

MAINTENANCE

  • TEF-MET®/B is a dry sliding bearing with a PTFE sliding layer. Lubrication is therefore not necessary, but basically possible!*

RANGE OF APPLICATION

  • Machine and plant construction, textile processing and agricultural maschines, automotive industry

CAPTION

Special dimensions are only available on request
*If you like to use lubrication nonetheless, please remember to lubricate the sliding bearing regularly.
