- L = Length of Rail
- P = Pitch of Rail (distance between mounting holes on center)
- E = “E” Dimension (distance from the edge of the rail to the first mounting hole on center)
HG series linear 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, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, HIWIN HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.
