The RV120HAHL-F Folded High Torque Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 120 mm diameter stage features DC drive equipped with a reduction gear providing higher torque and payload inertia capacity. It features a high-resolution direct reading encoder for superior repeatability, position stability. 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.
