💡 What is a roller follower used for in linear slide unit and cam applications? Roller followers give low-friction rolling support to guide motion and carry loads. - Ideal for converting rotary motion to linear movement in cam and indexing systems. - Preferred where rolling contact beats a sealed ball bearing for shock or edge loads. - Caged metric followers work well in linear slide unit installs; consider ceramic elements for high-temp or corrosive work.
