Vacuum High Torque Rotation Stage, 120 mm, Full-Step Drive
The RV120PEBV6 High Torque Vacuum Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 120 mm diameter stage features a Full-step stepper drive equipped with a reduction gear providing higher torque. All RV stages are constructed of tool steel, with rotation accuracy ensured by ground bearing surfaces. A double row of preloaded bearings allows for high off-center loads in a reduced footprint. The single monolithic design offers improved stiffness without compromising dynamic performance. Precise rotation is ensured by a precision ground and hardened worm gear. A rotary encoder mounted on the worm gear shaft provides 0.001° position feedback resolution.
Note: The cable supplied with the stage is not vacuum compatible due to various feed-through configurations and customer preferences. Please contact Newport for vacuum compatible cable options.
