Perfil de Guia Linear - Tipo RN

The type RN linear guideway is the logical optimised version of the R guideway. It has identical installed dimensions, but due to the larger contact surfaces of the guideway tracks is, however, higher performing. The reduced gap width between the guide rails also provides better protection against dirt.
