Tungsten Disulfide (WS2) is an industrial aerospace coating technology developed by NASA to improve the durability and performance of complex mechanical systems aboard everything from the International Space Station to probes that mapped the surface of Mars. With an astonishingly low dynamic coefficient of friction, coming in at just .030 when applied to the steel race components of our Ceramitech bearings, the WS2 coating significantly improves performance with mind-bending savings of 3-5 watts in most applications.
