💡 What is a caged roller bearing used for in linear slide units and heavy-duty machinery? Caged roller bearings carry heavy radial loads while keeping rollers aligned and lubrication managed. - Ideal for linear slide unit guides, conveyor rollers, and machine tool spindles - Sealed ball bearing designs keep grease in and contamination out for longer service life - For extreme speed or low friction, consider ceramic rolling elements; for heavy loads, high-carbon steel is common
