COM-KU®/D D400*

Fibre-reinforced compound plain bearing in wound technology | Maintenance-free | High load capacity

Bearing properties

  • COM-KU®/D is a self-lubricating and maintenance-free compound plain bearing. It has good sliding properties and is suitable for loads (also impact loads and with edge pressures). Good damping properties, very suitable for low sliding speeds, good chemical resistance, and long service life. Suitable as a replacement for lubricated bearings.


  • Compound plastic in winding technology

Tolerance details

  • Housing ø H7
  • Bushing inner ø after installation Depending on the diameter. It should be kept in mind that this material's installation dimensions and tolerances must be designed "in accordance with the plastic", i.e. taking into account an extended coefficient of expansion compared to metallic plain bearings.
  • Shaft tolerance Depending on the application

Shaft material

  • Steel > 200HB grinded, roughness < Rz 4

Mounting advise

  • Housing Installation chamfer, approx. 1.5 mm x 15 to 45°
  • Shaft Installation chamfer, 5 mm x 15°, edges rounded
  • Installation mandrel It is advisable to use a suitable press-in mandrel.

Range of application

  • Machine construction, construction machinery, agricultural machinery, shipbuilding, offshore plants

* Other suitable materials are also available on request for higher requirements, for example for higher temperature ranges.
