MP-410

MP-410 bearing structure

MP-410 is a thermoplastic material with a wire of fibers mixed with solid lubricants. This product has a good high thermal resistance, wears resistance and is developed for resistance to high loads static and dynamic. The MP-410 series includes cylindrical and flanged bearings as well as washers, and special parts are available on demand.
