POM bearings

Minimal maintenance under severe operating conditions

POM bearings have been specially developed for marginally lubricated applications and can thus function for long periods with minimal lubrication. The POM bearings are produced according to ISO 3547.

Applications of POM bearings

THN POM Plain Bearings Application 01 1

POM bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

  • Hydraulic applications
  • Elevators
  • Transportation
  • Mechanical engineering
  • Construction machinery

Materials

POM bearings are made from a steel backing to which a sintered bronze layer is applied. A POM top layer is then applied to this bronze layer. The bronze intermediate layer ensures efficient heat dissipation and makes for a strong joint between the steel backing and the sliding surface.

The steel backing is provided with a layer of copper or tin to prevent corrosion, while the POM top layer incorporates grease pits to retain the lubricant.

Lubrication

We recommend lubricating POM bearings with grease. The grease must contain an antioxidant for environments with temperatures over 50°C. Greases containing EP additives or significant amounts of graphite or MoS2 are not generally recommended.

Lubricating with oil is only advisable with applications in which the oil temperature does not exceed 70°C.
