Cross Roller Guide VR4080
In model G&S, 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 the 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.
Model VB is a low-friction, high-accuracy, fi nite LM system consisting of precision steel balls, arranged in short pitches in a ball cage model B, and a dedicated rail model V.

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.
