RH-N
Solid shaft gearheads

Highest flexibility and precision, the way you want it

The solid shaft gearheads of the new RH-N series are based on our compact RV-N component sets. They feature an integrated drive pinion and a motor flange for all current motor types. That makes these precision gears ideal for use in machine tools, in modern rotary tables and in different handling applications.

Solid shaft gear heads, customizable, low-maintenance

Integrated drive pinion and motor flange for current motor types

Completely enclosed,
pre-filled with lubricant

High precision

The RH-N series was specially developed for the European market and is manufactured locally. The gearheads achieve outstanding torque performance as well as a high degree of precision in a compact design! Since a drive pinion and motor flange for all current motor types are already integrated in the gearhead, integration in the drive train is fast and easy. An uncomplicated plug & play solution for every machine design engineer!

We deliver the gearheads of the RH-N series pre-filled with lubricant (optionally with H1 grease) and completely enclosed. This makes them ideal for palletising applications in medical technology and foodstuff production! These eccentric gears are also used in milling heads. On request we can adapt them to your individual application!
