💡 What is a roller bearing for sheaves used for? They support rotating sheaves and pulleys under heavy radial loads for lifting and conveying gear. - Ideal for sheaves, pulley blocks, cranes, hoists and conveyor rollers; helps reduce friction and wear - Works alongside sealed ball bearing assemblies and can replace or complement them in some setups - Choose one with oil-hole inner rings for easier lubrication and longer service life in industrial rigs - Also compatible with linear slide unit integrations where large radial load capacity is needed
