Product Description:
CNC Linear Slide Block GRH30CA GRH30HA Rail Guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial ,reserse radial and lateral directions,and self-aligning to absorb installation-error. Thus GH series linear guideways can achieve a long life with high speed,high accuracy and smooth linear motion.
