Properties

  • Excellent sliding and wear behaviour, high load capacity, shock resistant, chemically resistant against acids and bases (ph-value 0-14), corrosion resistant

Materials

  • Edelstahl/PTFE
  • Support material 1.4301 (1.4401 on request)
  • Intermediate layer Sinterbronze
  • Sliding layer PTFE

Material Properties

  • Specific load capacity static ≤ 250 [N/mm2]
  • Specific load capacity dynamic ≤ 140 [N/mm2] at low sliding speeds
  • Sliding speed ≤ 2.0 [m/s]
  • Friction value *** 0.02 [µ] to 0.20 [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 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.

Maintenance

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

Range of Application

  • Pharmaceutical and chemical industry, medical engineering, food industry, fittings

Caption

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