A process is provided for lubricating and protecting bearings in steel and process mills. In the process, metal is processed in the mill and conveyed on caster rollers. The caster rollers are lubricated with a special grease which enhances the longevity of the rollers, protects the rollers from rust and corrosion, and prevents the grease from leaking out of the rollers. In the preferred form, the grease comprises a water-resistant polymer to prevent the grease from washing out of the rollers and bearings when the metal workpiece is quenched with a high pressure water spray.
