  • Specific load capacity dynamic ≤ 140 [N/mm2] at slow sliding speed
  • Sliding speed ≤ 2.5 [m/s]
  • Friction value *** 0.02 [µ] to 0.20 [µ]
  • Temperature strain – 200 [°C] bis + 280 [°C]
  • Max. PV-value 1,8 [N/mm² x m/s]

Tolerance Details

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


  • 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


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