With fully interchangeable design that lets users combine any type of runner block with any profiled rail of same size, Roller Rail System High Precision (RSHP) Roller Rail Systems promote precise machining with high-quality surface finishing. Steel-insert entry zone in runner blocks reduces pulsation in transition to maximum load, universal lubrication concept minimizes required number of block types, and modular sealing protects bearings in cutting production against contamination.
