MP-400

Description

MP-400 is a thermoplastic material with a wire of fibers mixed with solid lubricants. This product are developed for use underwater, in atmospheres with high humidity and it has a very low moisture absorption, good chemical resistant, high temperature resistance and high mechanical loading resistant. The MP-400 series includes cylindrical and flanged bearings as well as washers, and special parts are available on demand.
