OILLLES #600 is a self lubricating
bearing without any other lubricants, and solid lubricants are filled in micro
spiracles which have been formed during special casting process in base metal.
The bearaing mainly consists of copper alloy with addition of aluminum , iron,
etc, which controls generation of crystals in solidification. This process develops
fine shrinkage pores or disc shaped pores for trapped gas. The base metal is this
porous copper alloy casting. The base metal is then impregnated with grade lubricant,
resulting in the bearing product.
