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. The single monolithic design offers improved stiffness without compromising dynamic performance. The largest RV stage can bear up to 6500N or rotate up to 80 °/s, while maintaining less than 4 um eccentricity.
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 (0.00025° resolution with RVS80CC) on the standard configurations. For more demanding applications, the HAT and HAHLT options are available on the RV120 to RV350 models. These stages are equipped with a direct reading optical encoder attached to the moving platen for superior resolution and accuracy.
The selection of the drive configuration should be based on the precision and speed requirements relative to the inertia of the payload.
• 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
