💡 What is a caged roller bearing used for? Caged roller bearings are built to take heavy radial loads and keep rollers spaced for reliable, low-friction rotation in industrial gear trains and shaft supports. Quick overview: - Excellent for heavy radial load applications like gearboxes, conveyor shafts, and mill rollers - Common choice around linear slide unit guides where high load capacity beats sealed ball bearing designs - Works well when oil holes allow regular lubrication; not the same as ceramic bearings but great where toughness matters
