radial plain bearing / polymer / metal
Schaeffler Technologies AG & Co. KG
The Schaeffler bearings with sliding layer E50 needs to be initially lubricated at the beginning of operation. The sliding layer is composed of polyoxymethylene or POM which is a high-molecule thermoplastic that is known for its low friction values, chemical and thermal stability. This layer is also composed of inert additives. The steel backing, sliding layer and the intermediate layer is composed of a triple layer material. The steel backing is equipped with a sintered porous tin-bronze intermediate layer that has pores filled with the sliding layer. They helps them withstand static contact pressures of 140 N/mm2. They have a small design envelope and a sliding speed of 2.5 m/s maximum.
