Cryogenic applications use in the harsh conditions such as the heavily load, high speed and low temperature. This research has constructed a tribo-test bench, it can operate under cryogenic environment. Through this experiment performed friction test with the cryogenic fluid, it came out the relationship the traction behavior with interacting in coated bearing components. Solid lubricants (silver, polytetrafluoroethylene) were shown the reasonable traction behavior under the cryogenic environment (low traction coefficient, rarely wear phenomenon). In addition, this work can discussion the overall trends of the solid films because it has a wide slip speed range (0.2 – 3.0 m/s).
