Callies Coated Main Bearings

Protect your high-rpm engine with Callies coated main bearings. A durable aerospace dry-film lubricant coating covers the main bearings to armor your engine during periods of marginal lubrication and cold-engine starts. Callies main bearings are specially prepped for the molybdenum-disulfide/graphite lubricant to be permanently bonded to the bearings' load-carrying surface. These coated bearings are especially great for engines using wet sump oiling systems. Guard your investment--use Callies coated main bearings in your race engine.
