The RV160HAT High Speed Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 160 mm diameter stage features a high speed DC drive enabling speeds up to 80°/s. This stage is equipped with a direct reading optical encoder attached to the moving platen for superior resolution and accuracy. 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.
