💡 What is a roller bearing for sheaves used for? A roller bearing for sheaves supports heavy radial loads in pulley and hoist systems and reduces friction for smoother operation. - Common in cranes, conveyors, winches and lifting sheave assemblies used in material handling and marine gear - Opt for inner ring oil holes or shields to simplify lubrication and extend service life for harsh conditions - Consider sealed ball bearing or ceramic bearing options when contamination resistance or higher speeds are needed - Can be paired with linear slide unit guidance in transfer systems where alignment plus load capacity is needed
