💡 What is a needle roller bearing used for in linear slide units? Needle roller bearings give compact, high-radial-load support where space is tight. - Compact high radial load capacity ideal for linear slide unit and cam follower setups - Often chosen over sealed ball bearing or ceramic options when axial space is limited - Handy in conveyors, gearboxes, and transmissions that need slim, heavy-duty rollers
