The ARC/HRC/ERC Linear Guide Series uses the O-type arrangement for the four row ball circulation design. The contact angle between the rail and ball is 45 degrees, and can realize the 4 directional load effects. cpc places special emphasis on strengthening the Arm length(LO), so when sustaining external force F, will have even higher Mr value to increase the rigidity and static moment capability. In addition, the runner block for the same size uses larger and more balls, so will outperform competitor’s models by 10% to 30% regarding load capabilities. The products have characteristics of high load, high moment, and high stiffness.

Total scraping of objects above 0.3mm Increase X-axis direction force capacity
Length of the Runner Block will not be increase Full lubrication contact with balls, suitable for short stroke movement.
All-Round lubrication holes system
Standard compact high dust proof seal Low friction non compact seal
