The high-precision powerhouse

This gearbox series sets standards in terms of power density, modularity and easy installation. It is used in all applications where the individual requirements far exceed what has previously been possible. RP+ gearboxes combine all the advantages of the familiar gearbox series:

- Reduced backlash of ≤ 1 arcmin

- Maximum power density

- Extremely smooth-running thanks to helical toothing
