RV-E Reducer

● Less than 1 arc-minute backlash
● Strong torsional rigidity, compact size
● Coaxial parts realize more design flexibility
● Integrated angular bearing with greater thrust and cantilever momentum
● High reduction ratio (up to 250:1) without increasing the size of the reducer
● Maximum torque to 5X rated torque (emergency stop)
● Standard coaxial RV-E reducer has excellent performance under very compact and high-precision component configuration. The components include rolling contact components to achieve higher efficiency and longer service life. The integrated angular bearing supports external loads, and the two-stage reduction design improves the reduction ratio while reducing vibration and inertia.
● RV-E model also has belt and pulley design options.
