• Suitable for rotating and oscillating movements.
  • Can be used where effective lubrication does not exist.
  • Low friction even without lubrication.

DEX is a 3-layer bearing, wrapped of copper-plated steel with a layer of POM.

The standard bearings are fitted with lubrication indents on the running surface. These lubrication indents serve as lubrication reservoirs and are aimed to be filled with grease before mounting the shaft. DEX-bearing is a boundary lubricated bearing which is especially suitable for constructions, where medium loads and relatively slow rotating or oscillating movements are occurring. The thin layers, which constitute the running surface of the bearing, ought to be well protected to avoid mounting damages and also for heating from e.g. welding.
