USED UNIVERSALLY FOR DECADES
Founded in 1909, RÖHM began successively expanding their product range by the area of power chuck technology
starting in 1950. Decades of experience and knowledge about power chucks make today‘s RÖHM power chucks so
successful. Especially for the machining of bar material, these are not only characterized by the high flexibility due to the
large through-hole, but also by the long service life, top precision and reliability.

POWER CHUCKS WITH
THROUGH-HOLE
ADVANTAGES AT A GLANCE
RÖHM power chucks with through-hole are successfully used both in bar and pipe machining,
as well as in the machining of flange-type workpieces. The proven wedge system allows maximum
clamping forces with maximum clamping precision at the same time. The rigidity of the power chucks
which contributes to this is achieved with a sturdy chuck construction.
Different toothing types for
different jaw variants
Easy spindle adaptation for
cylindrical centering mount
or short taper mount
Large through-hole for hollow
and partially hollow center
clamping
Large through-hole optimal for bar machining
Proven power chucks with long service life
Wedge hook system for high load capacity and clamping precision
High load capacity
thanks to proven
wedge hook system

6. Slot nut
Two- and three-jaw chuck, with large through-hole, for very high speeds.
The construction principle of the power chuck KFD-HS consists of absorbing the centrifugal forces which occur
during machining to the degree that the clamping force is hardly influenced.This occurs thanks to a special
type of wedge hook connection. Even for extremely high speeds, the clamping force drop is very low.The high rigidi-
ty is achieved through the screw connection between the chuck body and chuck flange. Thus, this chuck type offers
the optimal precondition for exactly machining shaft-type and flange-type workpieces.

Standard chuck for use on modern turning machines. A large through-hole allows both bar and pipe machining
as well as the machining of flange-type workpieces. The power is transmitted via the proven wedge hook system.

KFD-HS
APPLICATION
Premium power chucks with through-hole for maximum speeds with simultaneously
low centrifugal force losses.
TYPE
Power chuck available with cylindrical center mount or short taper mount.
3-jaw version with serration (90°) or tongue and groove.
2-jaw version with serration (90°).
CUSTOMER BENEFITS
Low centrifugal force losses and high speeds thanks to special wedge hook
system with annular piston
Larger than average through-hole for wide range of workpieces
Maximum precision thanks to rigid chuck construction
If necessary quick conversion to a different spindle nose by simply exchanging
the centering adapter
TECHNICAL FEATURES
- Universal construction of the piston connection (piston does not project into the
spindle bore area, even with the piston position moved back)
- Long jaw guide
- Clamping inserts can be used for bar machining (special version)
Included in the scope of delivery:
Chuck, chuck and jaw mounting screws, mounting wrench, slot nuts (without top
jaws)

Gripping force/speed diagram
(3-jaw chucks only)
The loss of gripping force was determined experimentally
on a chuck with matched UB top jaws. It is largely
independent of the initial gripping force at zero speed.
Upper curve:
min. centrifugal
force of top jaw
Lower curve:
max. centrifugal
force of top jaw
To obtain the specified gripping forces, the chuck must
be in a perfect condition and lubricated with F 80 lubri-
cant recommended by RÖHM. Measuring point
near chuck face.

Powerchuckwith
through-holeKFD-HE
KFD-HE
APPLICATION
Standard power chuck with through-hole for bar and tube machining, as well as for
flange-type workpieces.
TYPE
Standard version with cylindrical center mount.
3-jaw version with serration (90° and 60°).
Universal draw tube adapter at serration (60°).
CUSTOMER BENEFITS
Large through-hole for hollow or partially hollow clamping
Long-tested chuck principle for maximum service life
TECHNICAL FEATURES
- Power transmission by means of wedge hook principle
- Direct lubrication of all wear surfaces
- Sturdy chuck construction
Gripping force/speed diagram
The loss of gripping force was determined
experimentally on a chuck with matched
UB top jaws. It is largely independent of
the initial gripping force at zero speed.
Upper curve:
min. centrifugal
force of top jaw
Lower curve:
max. centrifugal
force of top jaw
To obtain the specified gripping forces,
the chuck must be in a perfect condition
and lubricated with F 80 lubricant
recommended by RÖHM. Measuring
point near chuck face.

Powerchuckswith
through-holeKFG
KFG - Power operated angle lever chuck
APPLICATION
Optimally suited for clamping tasks demanding through-hole, flexibility, large strokes
and low frictional losses.
TYPE
Angle laver power chuck with cylindrical center mount.
CUSTOMER BENEFITS
Large through-hole
Large jaw strokes and flexible use can be realized with angle lever system
High efficiency thanks to low frictional losses (low-hysteresis chuck)
Long service life - all moving parts are hardened and ground
TECHNICAL FEATURES
- Wide guidance of base jaws
- T-slots in the chuck body
- Lubrication of the jaw guide via easily accessible grease nipples on the axes of
the angle lever
Included in the scope of delivery:
Chuck, chuck and jaw mounting screws, wrench, slot nuts, 2 wrenches for the
sliding sleeve (without top jaws)
Big range of applications thanks to large through-hole. Suitable for bar machining and other different workpieces.
The axial pull force is translated into the radial jaw movement supported by the angle lever.
KFG - Extra large jaw stroke

QUICK-ACTING JAW CHANGE SYSTEM WITH INDIVIDUAL JAW UNLOCKING
Video DURO-NCVideo DURO-NCSE
The quick-acting jaw change system allows flexible use of the power
chuck and drastically reduces of set-up times. The jaws can be flexibly
offset, turned or changed.
Thanks to the individual jaw unlocking on the DURO-NCSE power
chuck, handling with large, workpiece-specific customized top jaws is
especially easy: Push the key till stop, then turn in the direction of the
arrow.

POWER CHUCKS WITH
QUICK-ACTING JAW CHANGE
Fast jaw change, high clamping precision and high clamping force characterize the power chucks
DURO-NCSE and DURO-NC. Thanks to the quick-acting jaw change system, the jaws can be
flexibly offset, turned or changed. The clamping precision of the chuck is always retained.
Precise and numerous jaw-
change options through tongue
and groove or using one-piece
jaws
Flexible use thanks to quick-acting jaw change reducing set-up times
Secure jaw lock via the safety key
Large through-hole optimal for bar machining
Fast and reliable jaw change
by simply unlocking the rotating pin
with safety key
Large through-hole for
hollow or partially hollow
clamping

DURO-NCSE
APPLICATION
Premium power chuck with through-hole for flexible use thanks to quick-action jaw
change system for maximum speeds.
TYPE
Power chuck available with cylindrical center mount or short taper mount.
3-jaw version.
CUSTOMER BENEFITS
Easy handling of the jaw change thanks to individual jaw unlocking
Universal: Jaws can be offset, exchanged or turned
For very high speeds - Low centrifugal force losses thanks to low jaw weights
and wedge bar construction
High clamping precision and clamping force thanks to rigid chuck construction
Large through-hole for hollow or partially hollow clamping
TECHNICAL FEATURES
- Power transmission by means of wedge bar system
- Lubricated base jaw guides
- The toothing of the wedge bar always engages completely in the jaw
- Base jaws with straight teeth
Note:
1) Included in the scope of delivery: Chuck, chuck and jaw mounting screws, base
jaws, safety wrench, mounting wrench.
2) The safety key can only be pulled out once the jaws are locked. This setup in
combination with the key switch integrated in the machine also prevents the
machine spindle from starting up unintentionally when the jaws are unlocked.
