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 coecient of friction and quite superior wear resistance.
Lower prices than bearings with copper alloy bases.
