SKF PCM161820M Metric Plain Bush 16x18x20mm

PCM-M Plain Bushings: Plain bushings of triple-layer POM composite material. Suitable for bearing arrangements that have to support radial loads only. For slow rotational or oscillating movements as well as linear movements. Initial lubrication required. Maintenance-free, except where there is a risk of misalignment, edge loading or moderate contamination.
POM Composite: POM composite bearings consist of a copperplated sheet steel backing that is covered with a 0,2 to 0,4 mm (0.008 to 0.015 inch) thick layer of sintered tin/bronze. The principal characteristic of these bearings is their relatively thick (0,3 mm or 0.012 inch) 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.
