Kä puɔth:CPC linear guide HR20ML belongs to high assembly series linear guide, combination height is 30mm, slider mounting hole is 50*32mm. If you compare with traditional sliding guide, the rolling guide's friction coefficient can be reduced to the original 1/50, because the starting friction is significantly reduced, relative to less non-effective movement occurs, so it can easily reach μm level feed and positioning.
