💡 What is a roller follower used for in linear slide unit and conveyor guide applications? A roller follower provides rolling support and reliable load transfer where track or cam contact is required. Quick breakdown: - Reduces friction and wear in linear slide unit and cam follower systems. - Crowned rollers help compensate for misalignment in conveyor guides and rails. - Caged, non-separable designs keep rollers aligned and allow easy lubrication through oil holes.
