“ZYTEL” NYLON RESIN AND “TEFLON” TETRAFLUOROETHYLENE RESIN AS BEARING MATERIALS

Both “Zytel” nylon resin and “Teflon” tetrafluoro-ethylene resin are being used extensively as bearing materials. Most of these applications have been developed independently and no attempt has been made to collect performance data in order to put future design on a firm basis.

Typical data on dry or partially lubricated bearings have been collected from a variety of sources. Work in our laboratories on lubricated bearings made of “Zytel” are reported for the first time.

In addition, physical properties of these materials are described. With these properties and the bearing work done to date, it is believed that the selection of the material and the design of bearings can be done with greater accuracy.
