Oiles 2000S Sintered oil-impregnated bearings with dispersed solid lubricant Feature ●Serviceable without the need for lubrication. Demonstrates higher performance when greased. ●Distributed solid lubricant allows motions in any direction. ●Features low coefficient of friction and quite superior wear resistance. ●Lower prices than bearings with copper alloy bases.
