💡 What is a roller bearing for sheaves used for in industrial pulley systems? It supports rotating sheaves and pulleys under heavy radial loads while reducing friction and wear. - Ideal for heavy radial load equipment like cranes, conveyors, hoists and winches where a robust roller bearing or sealed ball bearing is preferred. - Maintenance note: shielded bearings with oil holes allow re-lubrication; consider ceramic options for high-speed or corrosive setups. - Match bearings with compatible parts such as linear slide units, pillow block bearings or flange bearings for proper alignment.
