Original THK Cross Roller Guide VR4-80x7Z VR4-120X11Z VR4-160X15Z VR4-200X19Z VR4-240X23Z VR4-280X27Z VR4-320X31Z VR4-360X35Z VR4-400X39Z VR4-440X43Z VR4-480X47Z Rails (VR3-400X39Z)

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.
