Low-maintenance and maintenance-free plain bearings. The name KS PERMAGLIDE®, a registered trademark of Rheinmetall Automotive AG, embodies the product characteristic of permanently low-wear sliding. The use of solid lubricants in the plastic matrix makes it possible to use PERMAGLIDE® plain bearings from material group P1 (maintenance-free materials) without oil or grease lubrication. It is not always possible to carry out plain bearing application tasks using products made from maintenance-free material. In these cases, low-maintenance P2 materials are the perfect solution. PERMAGLIDE® plain bearings are available as bushes, collar bushes, washers, strips or other designs.
