PCMW527802M Metric Thrust Washer 52x78x2mm

PCMW-M Thrust Washers: Thrust washers of triple-layer PTFE composite material. Suitable for space-saving axial locating bearing arrangements. For slow rotational or oscillating movements. Initial lubrication not required. Maintenance-free.
POM Composite: POM composite bearings consist of a copperplated sheet steel backing that is covered with a 0,2 to 0,4 mm thick layer of sintered tin/bronze. The principal characteristic of these bearings is their relatively thick (0,3 mm) layer of acetal resin (POM – polyoxymethy­lene) that is firmly attached to the sintered tin/bronze layer. The covering layer has pockets to retain grease. The thickness of the covering layer makes these bearings less sensitive to misalignment and the edge loading associated with that misalignment.
