Rotary positioning stage RV series

motorizedclosed-loopprecision

The RV Series steel rotation stages combine high precision positioning and extremely high load capacities to operate in a large variety of conditions for scientific and industrial applications. Five stage sizes and four DC motor configurations are available. Closed-loop DC servo systems are the recommended choice for more demanding applications requiring either higher rotational speed, repeatability, accuracy or smaller minimum incremental motion (MIM). •Ideal for high load applications with up to 6500 N load •All steel, single monolithic construction offers high stiffness and thermal stability •Double row preloaded ball bearings allow for high off-center loads in a reduced footprint •Precision ground and hardened worm gear with self-compensating preload •Closed-loop DC motor for high speed, repeatability, accuracy or smaller MIM Steel Construction The tool steel construction ensures enhanced rotation accuracy due to the ground bearing surfaces. The single monolithic design offers improved stiffness and thermal stability without compromising dynamic performance. Highest Load Capacity The double row of preloaded ball bearings allows for higher off center loads for its small footprint. The largest member of the RV DC motor product family can bear up to 650 kg or rotate up to 80 °/s while maintaining eccentricity of less than 4 µm.
