Original THK Cross Roller Guide VR3-50x7Z VR3-75x10Z VR3-100x14Z VR3-125x17Z VR3-150x21Z VR3-175x24Z VR3-200x28Z VR3-225x31Z VR3-250x35Z VR3-275x38Z VR3-300x42Z Rails (VR3-175x24Z)

In the Model VR, precision rollers are orthogonally aligned one after another in a roller cage that is combined with a dedicated rail having a raceway cut into a V-shape groove. When two units of the cross-roller guide are mounted in parallel, the guide system is capable of receiving loads in four 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 Model VB is a low-friction, high-accuracy, finite LM system consisting of precision steel balls, arranged in short pitches in a Model B ball cage, and a Model V dedicated rail. The cross-roller guide and the ball guide are used in the slide units of various devices such as office automation equipment and peripherals, measuring instruments, printed circuit board drilling machines and other precision equipment, optic measuring machines, optic stages, handling mechanisms, and X-ray machines. Long Service Life, High Rigidity With a unique roller retaining mechanism, the effective contact length of the rollers is 1.7 times greater than the conventional type. Furthermore, the roller pitch interval is short and a sufficient number of rollers are installed, thus increasing the rigidity by two and the service life by six times greater than the conventional type. As a result, a safety-oriented design against vibrations and impact, which commonly occur in ordinary straight motion mechanisms, can be achieved. Smooth Motion With model VR, the rollers are individually held in a cage and roller pockets formed on the cage are in surface contact with the rollers to increase grease retention. Thus, smooth motion with little wear and friction is achieved. Highly Corrosion Resistant Model VR series and model VB series both include types made of stainless steel, which is highly corrosion resistant.
