POM-MET® is an economical wrapped bushing. It consists of a steel backing and a sliding layer made from POM. It has very good wear behaviour and a low frictional value; is creep resistant and shows good results in a “dirty” environment for outdoor usage.
POM-MET® bushings are made from a steel plate, where the POM is sintered onto the surface, using a bronze powder intermediate layer as a bonding agent. These raw material plates are then cut to a rectangular shape, then wrapped and calibrated to the right size.
The sizes are according to DIN 1494/ ISO 3547 with tolerances to be press fitted into a H7 housing for a h8 shaft tolerance. The sizes are identical to our TEF-MET® series, but POM-MET® is the better choice for more abrasive applications.
MoS2 is a friction modifier and is often used in heavy duty greases for its good resistance to compression. However, POM-MET® is not completely maintenance-free, as periodical greasing is still necessary. Hence, the sliding layer is perforated with lubrication pockets.
POM-MET® is often used in cranes, truck cranes, tail gates, harbour equipment and agricultural machinery and construction machine
