HIWIN RGR profile rails are roller-type linear guideway rails from the RG/QR series, designed for heavy-duty applications with the highest requirements in terms of load capacity and torque load capacity. The RG series uses rollers as rolling elements, where the linear contact surface dramatically reduces deformation under load, achieving very high rigidity in all directions.

With SynchMotion™ technology (roller chain), the RG series becomes the QR linear guideway — delivering higher travel speeds, extended relubrication intervals and smoother, lower-noise operation.

Compatible with the corresponding HIWIN RG/QR blocks, available in multiple sizes and standard lengths.
