RV-E gears are the right choice for demanding drive tasks. If high torsional rigidity and tilt stability, as well as a compact design with large reductions are required, this is the solution.

The RV-E series combines the RV gears with large, integrated angular ball bearings. They absorb extreme forces and torques. An additional external bearing is unnecessary. The result is precision gears in a compact design with extreme rigidity and a permanently constant operating behaviour. The nearly one-hundred-percent contact within the trochoidal pin construction and the even distribution of force within the gear enable a high load with little play. Thanks to this design, the RV-E gear achieves a high level or repeat accuracy and path accuracy. In the zero crossing of the hysteresis the maximum opening is one angular minute.
