Servo right-angle gearheads

High End

and SPK

New right-angle precision as classic shaft
version

The successor to our versatile hypoid
gearhead with SP

compatible output shaft

(SK

), with optional planetary stage (SPK

RPK

The new high performance right-angle
gearhead

The RPK

sets standards in terms of

power density, modularity and ease of
installation – together with even greater
design freedom.

HIGH TORQUE

New right-angle precision as flange version

The successor to our versatile hypoid
gearhead with TP

compatible output

flange and hollow shaft (TK

), with

optional planetary stage (TPK

/TPK

HIGH TORQUE).

Increased productivity

Do you need a machine that operates at maximum
productivity? Your servo right-angle gearhead offers
200% more torque, 100% faster speeds than equiv-
alent products and thus creates the perfect condi-
tions for maximum manufacturing efficiency.

Simple and convenient

From an optimized design with our cymex

software

to the classic, patented WITTENSTEIN alpha motor
mounting and oil/grease volume adapted to each
model – WITTENSTEIN alpha right-angle gearheads
make your life so much easier.

The plus stands for torque

The servo worm gearhead with solid shaft,
hollow shaft and hollow shaft flange outputs.

Output type:
VDH

: Hollow shaft, smooth or keywayed

VDT

: Output flange, flanged hollow shaft

VDS

: Output shaft, smooth, keywayed, involute

Reliable and accurate

The low torsional backlash and high torsional rigid-
ity of your WITTENSTEIN alpha right-angle gear-
head assure maximum positioning accuracy of your
drives and precision of your machines – even during
highly dynamic operation up to 50,000 cycles/hour.

Maximum durability

Your WITTENSTEIN alpha right-angle gearhead
is extremely reliable due to the overall design and
100% WITTENSTEIN alpha inspections:

“mount and

forget”

. A length compensation feature integrated

in your WITTENSTEIN alpha right-angle gearhead as
standard maximizes the lifespan of your servo motor
during high-speed continuous operation.
