Thermoplastic sliding bearing

Technical details COM-KU® / S

  • DIN EN ISO 3547-1
  • maintenance-free
  • Cost effective
  • Available in great measurement diversity


  • Dry sliding bearing of good value.
  • Suitable for simple applications and axial movements.


  • Compound plastic produced by injection-molding*

Material properties

  • Specific load capacity static ≤70 [N/mm2] dep. on temperature and length of strain
  • Specific load capacity dynamic ≤40 [N/mm2] dep. on temperature and sliding speed
  • Sliding speed <1,0 [m/s]
  • Friction value ** 0,08 [µ] to 0,2 [µ]
  • Temperature strain -50 [°C] to 100 [°C]
  • Max. PV-value 0,6 [N/mm² x m/s]
  • Moisture absorption: 0,1 [ % at 20°C in 24h ]

Tolerance details

  • Housing Ø H7

  • Shaft tolerance h – Tolerance (recommended h9)

Shaft material

  • Steel >200HB dressed to size, surface roughness < Rz 4

Mounting advise

  • Housing: Mounting bevel, min. 1,5 mm x 15-45°
  • Shaft: Mounting bevel, 5 mm x 15°, edges rounded
  • Force fitting mandrel: The application of an adequate force fitting mandrel is advisable.


  • Not necessary. COM-KU®/S is a maintenance-free plastic sliding bearing. Additional lubrication is possible.

Range of application

  • Machine and apparate construction, agricultural machinery, fittings, conveyor technique


* On request further materials are available for higher demands, e.g. for higher temperature ranges.

** The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change.
