Cross Roller Guide
THK Cross Roller Guides, model VR, consist of precision rollers, which 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 can receive 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.
In addition, Model VB is a low-friction, high-accuracy, finite LM system consisting of precision steel balls, arranged in short pitches in a ball cage model B, and a dedicated rail model V.
The Cross Roller Guide and the Ball Guide are used in the slide unit of various devices such as OA equipment and its peripherals, measuring instruments, precision equipment including a printed-circuit-board-drilling machine, optic measuring machines, optic stages, handling mechanisms and Xray machines.
