          MSC stainless steel series are applied two rows with Gothic-arch groove and designed to contact angle of 45° which
          enables it to bear an equal load in radial, reversed radial and lateral directions. Furthermore, ultra compact and low      Accuracy grade          N, H, P
          friction resistance design is suit to compact equipment. The lubrication route makes the lubricant evenly distribute        Stainless steel
          in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this        Code of special rail         No symbol, A, B ...
