The Coefficient of Friction of PTFE, 25% Glass Filled, slide plates has been reported to be from 0.01 to 0.2. This depends on the surface preparation, loading, velocity, and the duration of the test. Bonding PTFE, 25% Glass Filled, to metal increases the load capabilities in excess of 2,000 PSI (For design purposes, use 500 PSI).

Size the linear-guide system. Static load consists of the weight of the saddle, nest fixture, payload, and bearings. If 40.0 lb is centered horizontally fore/aft and left to right in a typical dual rail and four carriage set, each of the bearing blocks would be statically loaded at 10.0 lb. Slides come in two basic types: saddle and cantilever.
