RPK

–

The new high performance right-angle gearhead

The new standard, also available
as a right-angle version

The new RPK

combines

the advantages of the RP

high performance plane-
tary gearhead with state-
of-the-art hypoid gearing.
The new interface to the
application simplifies instal-
lation and ensures maxi-
mum power density.

The RPK

impresses

with maximum power density

· If your drive requires maximum performance
· If you value world-class engineering
· If you require an even more compact system

Performance data for right-angle version

Sets standards in terms of power density, modularity and easy installation.

The geometry of the RPK

output flange is perfectly adapted to

the high power density.

The RPK

high performance right-angle gearhead is optimized

for rack and pinion applications.

Right-angle gearheads

High End

High Performance Linear System

For use where the individual

requirements far exceed what has

previously been possible.

Compared to the industry standard, the

values have been improved by 150%

on average!

The integrated slots reduce the design

and installation requirements to

a minimum.

The pinions, which are specially

adapted to the gearhead enable the

transmission of maximum

moving forces.

Performance data for linear system

Flexibility during installation

The RP

is also available as the RPM

actuator version. The RPM

combines the advantages of the RP

series in an even more compact

design. Thanks to its special design, the permanently excited servo
motor ensures maximum power density.
