OILES 2000S Sintered multi-layered bearing containing dispersed solid lubricant

CUSTOMIZED PRODUCT

Economical bearing which is usable for any direction
OILES 2000S is a self-lub bearing containing graphite as main solid lubricant based on newly developed special metal. Further process to contain lubricant oil therein is conducted. Features Usable without lubrication; however, expected better performance with grease Usable for any designated direction because of solid lubricant dispersed in the product Outstanding low friction coefficient and extreme wear resistance Low cost in comparison with a bearing based on copper alloy
