💡 What is a cam follower used for in linear slide unit applications? It’s a specialized roller that follows cam profiles and guides linear motion with high load capacity. - Transfers heavy radial loads in cam mechanisms and linear slide units, often used instead of sealed ball bearing options - Common in conveyors, indexing tables, and automation systems where reliable guided travel is needed - Full-complement crowned rollers improve contact area and reduce edge stress, helping linear slide units last longer
