MRP all-purpose bearings
The MRP has a unique added lubricant embedded within the surface of the liner material to decrease the initial coefficient of friction. This small change was initiated because in certain lightly loaded joints, upon initial actuation, an intermittent stick-slip or noise could be generated. The MRP addresses this issue by decreasing friction and virtually eliminating the typical break-in period.
PolyLube MRP bearings are designed to minimize wear; however, the bearing wear is affected by the general operating conditions, such as speed, sliding distance and load. With intermittent rotation or oscillation, radial wear should be negligible over thousands of hours. Hard chrome plating gives excellent wear performance and protects the shaft from corrosion. Softer coatings such as cadmium or zinc may exhibit different wear characteristics but are perfectly suitable for use against the MRP surface.
