1 Features and Types Features of the Table Stopper bolt Rail Clearance adjustment bolt Rail Base Roller Cae Structure and Features Fi.1 Structure of the The is a compact, hihly riid finite linear uide unit that has the Cross Roller uide(s) between the precision-machined table and base. There are two types of the : model VRU, and a miniature type model VRT. The is used in extensive applications such as OA equipment and peripherals, measurin instruments and printed circuit board drillin machines.

2 [Easy Installation] Since the Cross Roller uide(s) is installed between the precision-machined table and base, a hihly accurate linear uide mechanism is achieved simply by mountin the product with bolts. [are Permissible oad] Since rollers with lare rated loads are installed in short pitches, the cross roller uide is capable of bearin a heavy load, achievin a hihly riid linear uide mechanism and ainin a lon service life. odel VRT [Diversified Usae] Since the rollers are orthoonally arraned one after another, the uide system is capable of evenly receivin loads in the four directions applied on the table. (See Fi.2.) odel VRT-A odel VRU Fi.2 oad Directions [Hihly Corrosion Resistant] The base and the table of models VRT- and VRT-A use stainless steel. Their rails, rollers, roller caes and screws are also made of stainless steel. As a result, these uide systems have sinificantly hih corrosion resistance. The base and the table of model VRU- are made of aluminum.
