The HIWIN RG Series roller-type linear guideways use cylindrical rollers instead of balls, providing 2–3× higher load capacity and rigidity compared to ball-type equivalents. The larger contact area of the rollers distributes loads more effectively, making the RG series the choice for heavy-duty machine tools, large gantry systems, and high-load automation.
