💡 What is a cam follower bearing used for in linear slide units and cam mechanisms? A cam follower bearing gives rolling contact between cams and guides to smooth motion and cut wear. - Handles radial loads and indexing forces in linear slide units and cam-driven setups. - Often chosen instead of a sealed ball bearing when higher load capacity or crowned rollers are handy. - Common in conveyors, automation, machine tools and other cam applications where alignment tolerance matters.
