HIR Cross Roller Guide is a compact, highly rigid LM system whose rollercage holding precision rollers orthogonallyaligned one after another travels by half thestroke on a V-shaped groove formed on a rail. Structure and Features In model VR, precision rollers are orthogonally aligned one after another in a roller cage that iscombined with a dedicated rail having a raceway cut into a V-shape groove. When two units of theCross-Roller Guide are mounted in parallel, the guide system is capable of receiving loads in thefour directions. In addition, since the Cross-Roller Guide can be given a preload, a clearance-free,highly rigid and smooth slide mechanism is achieved. The Cross-Roller Guides are used in the slide unit of various devices such as OAequipment and its peripherals, measuring instruments, precision equipment including a printed circuit board drilling machine, optic measuring machines, optic stages, handling mechanisms and XRay machines.
