MP-410 bearing structure

MP-500 is a thermoplastic material with a wire of fibres mixed with solid lubricants. This product has an optimal resistance at high temperature, excellent mechanical properties good wear resistance, optimal chemical resistance and the solid lubricants reduce the coefficient of sliding friction and they form an optimal sliding surface with the counter- piece. The applications can be various: ranging from office supplies, medical equipments, pneumatic cylinders hinges, pedal controls, etc. The MP-500 series includes cylindrical, flanged bearings, washers and special parts.
