Linear Guideways GRH30CA GRH30HA Linear Rail Guide Block Components
For Robotic Systems
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.
