Oiles 2000 Sintered multi-layer bearings with dispersed solid lubricant Feature ●Dispersed solid lubricant allows motions in any direction and offers superior performance for minute movements. ●Serviceable without the need for lubrication. ●Features superior load resistance, speed characteristics, and wear resistance. ●Standard products and plates for additional machining are available in various sizes. The values in parentheses are static bearing pressures, which are the bearing pressures in applications with no motion or very small motion (≦0.0017m/s[0.1m/min]).

Do not machine sliding surface. ※Contact us for grinding and milling information. ※The value shown above are for sintered layer. ※The values shown above are typical values, not the standard values. Oil Impregnation Method If the Oiles 2000 material is purchased and used by finishing it, it should be oil-impregnated after machining and then assembled in the housing. When the bearing is stored for long or washed, it should be oil-impregnated again and then assembled in the housing. For the method, see the description about the oil impregnation method shown on page 246. Dip the machined bearing in lubricating oil for 24 hours or more before using it, if oil impregnation (by heating) is disabled.
