Precision 80–350 mm diameter rotation stages
Monolithic design ensures high structural stiffness
Ideal for high-load application
High-accuracy versions with direct reading encoder and better than 0.0001° (0.36 arcsec) resolution
The RV Series rotation stages provide high-precision angular positioning accuracy combined with high load capacity. There are five stage sizes and six drive configurations available, optimizing load capacity, torque, speed and resolution for a variety of operating conditions. 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, and the single monolithic design improves stiffness without compromising dynamic performance. The larger models, RV120PP to RV350PP, feature a worm mounted rotary encoder for improved accuracy and repeatability and the full-step PE version is equipped with a reduction gear providing higher torque. The DC motor-driven CCHL and HAHLT versions are equipped with a reduction gear providing higher torque and payload inertia capacity. The HAT and the HAHLT feature a high-resolution direct reading encoder and tachometer for superior repeatability, position stability and speed regulation.
The selection of the drive configuration should be based on the precision and speed requirements relative to the inertia of the payload.
For critical positioning applications, Newport offers micropositioning calibration services. We will create, implement and verify an electronic compensation process to improve the absolute position accuracy of RV-HA series stages when commanded by our XPS advanced motion control system. Compensation is performed at 20.0 °C, +/-0.2 °C, for linear and non-linear errors, ensuring accuracy of up to 0.001°. A certificate of calibration per Newport Metrology Procedure A167 and measured error maps are provided. Click here for complete information.
