Ball-Screw Positioning Tables

IDC URS-Series ball-screw positioning tables use a special "U"-shaped steel guide rail and a recirculating bearing module that serves as both a guide block and ball-screw nut.


The bearing module contains four preloaded ball circuits for high load capacity, accuracy, and rigidity while the rigid "U"-shaped guide resists bending for cantilevered applications.

The URS-Series comes in five standard sizes from 20-mm tall by 40-mm wide to 55-mm tall by 100-mm wide in travel lengths to 1,134 mm and load capacities to 530 kg.
