Ganro Rear Motor Mount Rotary Tables


Ganro Industrial Corporation produces two of the most popular size rotary tables with a rear mounted motor for those smaller vertical machining centers. The rear motor mount rotary table design is available standard in the 170mm (6.69”) and 250mm (9.84”) faceplate diameters. As with other Ganro rotary tables they can be utilized as a full rotating axis incorporated into a machine’s control or as an indexer with Ganro’s M-Mate AC servo controller. All Ganro rear motor mount rotary tables and indexers use Ganro’s core technology of a double lead worm shaft and worm wheel system for high precision and reduced backlash. Ganro rotary tables are assembled using cross cylindrical roller bearings with high rotation accuracy capable of bearing heavy loads in every direction.
