ROLLER BEARING LUBRICANTS

摘要

A synthetic bearing lubricant prevents wear even under very high loads and is such that when it contaminates the rolling lubricant the rolled product is not stained. The bearing lubricant contains poly-isobutene, at least one ester of a C2 to C5 alcohol with an alpha -hydroxy-mono carboxylic acid or an alpha -hydroxy-dicarboxylic acid, and at least single or poly unsaturated C13 to C19 carboxylic acid.
