💡 What is a roller follower used for in linear slide units and cam follower applications? A roller follower guides shafts and cams to carry radial loads with low friction. Use cases: - Linear slide units, camshafts and cam tracks where crowned rollers reduce edge loading - Replaces sealed ball bearing setups for heavy radial loads and misalignment tolerance - Handy on conveyors, indexing mechanisms and as an alternative to pillow block bearing designs
