💡 What is a roller follower used for in linear slide units? A roller follower provides rolling contact to guide motion, carry radial loads, and keep alignment in cam-driven or sliding systems. It is a handy component for motion control and bearing replacements: - Supports heavy radial loads and cuts friction in linear slide units and guideways - Ensures accurate tracking on cams, conveyors, and indexing mechanisms for smooth motion - Serves when a caged, shielded roller is preferred over a sealed ball bearing or pillow block bearing
