💡 What is a cam follower used for in linear slide units? A cam follower provides smooth rolling contact and precise guidance for cams, tracks, and linear slide units in machinery. - It transfers radial and axial loads with minimal friction, similar to a sealed ball bearing in compact spaces. - It works well in automation, conveyors and indexing tables where crowned rollers keep tracking on cam profiles. - For high-speed or low-wear needs consider ceramic elements or sealed ball bearing alternatives for longer life.
