💡 What is a roller follower used for in linear slide units and cam follower applications? Roller followers are a handy way to provide rolling contact and guided motion with reduced edge loading. - Commonly used in linear slide units, conveyor systems, indexing tables and cam mechanisms for precise guidance. - Crowned rollers help prevent edge stress and improve load distribution in track or rail applications. - Separable caged designs are handy for maintenance, inspection and when an inner ring is not required.
