Properties

  • Excellent sliding- and wear behaviour, for all types of movement, high load capacity, all-round adaptable

Materials

  • Support meterail Steel tin-plated
  • Intermediate layer Sintered bronze
  • Sliding layer PTFE

Material Properties

  • Specific load capacity static ≤ 250 [N/mm2]
  • Specific load capacity dynamic ≤ 140 [N/mm2] at low sliding speed
  • Sliding speed ≤ 2.5 [m/s]
  • Friction value *** 0.03 [µ] to 0.25 [µ]
  • Temperature strain – 200 [°C] to + 280 [°C]
  • Max. PV-value 1.8 [N/mm² x m/s] 3.6 [N/mm² x m/s] for a short time

Tolerance Details

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

Shaft Meterial

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

Einsatzgebiete

  • Maschinen- und Apparatebau,Textilmaschinen, Büromaschinen, Druckmaschinen, Fahrzeugbau

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