Nature's Plastic
The advantage of the special POBCO-B HARDWOOD over most bearing-grade plastics is that it affords a MORE RIGID, DIMENSIONALLY STABLE material coupled with a material which is 100% LUBRICANT FILLED to render a lower coefficient of friction and LONGER LIFE. Plastics sometimes lose their capacity to stay dimensionally stable under changes in temperature. The larger profile plastic shapes may also lose their capacity to stay straight along a linear path due to the lack of rigidity inherent in many plastics. Therefore for CHAIN and CABLE GUIDES and similar applications POBCO-B HARDWOOD should be seriously considered.
