This study is the manufacture of solid lubricant oilless bearing using sintered parts. PTFE was as organic solid lubricant and $MoS_2$ as inorganic solid lubricant, and its characteristics were studied. Thickness of lubricant was suited 25~$100mu extrm{m}$ for lubricant characteristics. Curring temperature of MoS_2$ film was 12$0^{circ}C$, 2 hours and that of PTFE film was $260^{circ}C$, 20 minutes. The solid weight and solid volume of $MoS_2$ film was 51.7% and 27.4%, and that of PTFE was 44.9% and 24.3%. Chemical resistant of PTFE solid lubricant oilless bearing was excellent as salt test was 520hours, and usable temperature range was $-200~+280 ^{circ}C$. Conduction of electricity can be increase by addition of graphite or $$alpha$- PbO_2$</TEX>. The electric conductivity was 100~180$Omega$.
