Perfil de Guia Linear - Tipo RNG

Like type RN, the type RNG linear guideway is based on the type R linear guideway. Like type RN, it has larger contact surfaces for the guideway tracks, which means its performance is significantly enhanced. Compared with types R and RN its cross-section is, however, smaller, which means that it represents a cost-effective solution without competition.
