💡 What is a roller follower used for in linear guide systems? Roller followers transfer radial loads and guide motion in cam and linear systems. - Helps carry radial and intermittent loads with low friction in linear slide units and cam followers. - Common in automation, indexing machines, conveyors, and machine tool feeds for precise guidance. - Consider caged separable designs for easier maintenance and replacement; compare with sealed ball bearing or ceramic options.
