1.3 Intended Use
Use the collet chucks only for the intended use. Insufficiently clamped tools or work-pieces, failure
to comply „safety and accident prevention regulations“, and the use of work-pieces and our
products on machines that are not intended for this propose, can result in personal injury and
damages to the clamping devices. In this case, we shall assume no liability. Do not apply force
during assembly, disassembly and operation; this could damage the clamping device or the
machine.
1.4 Initial start-up
A function check is implicitly before initial operation of the collet chuck. To ensure a safe and
precise operation of the collet chuck during machining, a sufficient clamping force must be
provided. Check the clamping force.
The collet chuck, especially the function surfaces must be clean and lubricated sufficiently.
Never exceed the axial and radial forces specified on the chuck. Pay attention to the max. RPM.
Check the clamping force regularly!
Do not operate the collet chuck without a clamping head mounted and a workpiece clamped.
Persons might get hurt or the collet chuck gets damaged.

2 Product description
This pull-down chucking system can be used on turning, grinding, milling and indexing table
machines. You can compose the individual chuck components as required due to the modularity of
the system. All you need is the maximum work piece diameter and the size of the spindle nose of
your machine.
The following types of SPANNAX®-chucks are available:
Through-hole chuck:
- Especially designed for bar material machining
- Mainly used on main-spindles
- Short and compact design
End-Stop chuck:
- Designed for insert parts on main and sub-spindles

- Optional: End-stop with air sensoring / back-purging
- Short changeover from end-stop to through hole by quick changeable end-stop
DL-Dead Length chuck:
- Designed for the use on sub-spindles
- Axial-force free clamping due to clamping by pushing
- Removable end-stop for insert parts
Your benefit:
- Safe clamping by constant clamping force also at increasing rotational speed
- High rigidity due to parallel movement of the clamping jaws
- Increasing flexibility of your production machine due to large clamping range ± 0,5mm
- Extension of working space due to compact design and reduction of interfering edges
To solve special clamping-jobs, we are pleased to build special chucks or adapt the

Intermediate sizes, inch-sizes and special profiles on request
The Ortlieb GT clamping heads are based on the proved RubberFlex ® - vulcanization. This
rubber-steel-connection can stand toughest conditions and guarantees a long life-time. Due to the
facial borings, the clamping heads are quick changeable but also precise, a TIR of ≤0,01mm are
possible (smooth boring). The clamping head with highest clamping force, high rigidity and
increased clamping tolerance of ±0,5mm is predestinated for bar-material machining. Especially
the double serrated type. Use the smooth type for second-side operation to prevent markings on
the surface of the workpiece.
Your benefit:
-High clamping force and rigidity
-Temperature resistant up to 100°C
-Long-term life-time
-High run-out accuracy of ≤0,01mm are possible (smooth boring)
-Clamping tolerance of ±0,5m

4.2 Changing devices
A changing device is necessary to change the clamping heads. Lever-operated or pneumatic-
operated changing devices are available.
Function:
The ergonomic-designed lever-operated changing device guarantees a fast and simple change by
internal power-enforcement with self-locking function which keeps the clamping head in squeezed
condition during changeover.
The pneumatic changing device needs a connection to compressed air. During the changeover,
the button must be pressed, to keep the clamping head in squeezed condition. This changing
device is designed for larger clamping heads (GT100) with a higher rubber-tension.

5 General Safety Instructions
1. Safety requirements to machines
-Operation of the machine spindle is only allowed, when the clamping pressure and clamping
force is in the acceptable range.
-Do not rotate the spindle without a workpiece clamped.
-On a breakdown of the clamping power a signal must stop the machine spindle and the
workpiece has to be clamped till a complete stop of the spindle.
-After a power breakdown and on return of the power, a changing over must not occur.
-During operation, the spindle and the clamped workpiece must be secured by a safety facility.
-The opening of the safety doors is only possible if the machine spindle stands still.
-All operations and maintenance to the spindle and the tool-gripper are only allowed if the
spindle stands still.
-Do not operate the chuck without a bayonet nut mounted. The safety screw to prevent rotation
to the pressure sleeve might get damaged.
2. Operation cylinders, machine spindles
To operate the chucks, please use only appropriate cylinders according the safety and accident
preventions regulations. Mounting the collet chuck to a spindle with an existing operating cylinder,
make sure that the clamping power is sufficient to clamp the workpiece and the maximum clamping
force is not exceeded! Connection parts and adapters must be designed to endurance strength.
Set and check the limit switch to check the stroke before initial operation.
3. Operating data
The allowed operating data, maximum clamping force and maximum revolutions shown on the
technical data sheet (Technical Data chap. 2.2) may not be exceeded. The minimum clamping
force depends on cutting rates.
4. Tools
Please use solely suitable clamping heads matching your chuck (see: Technical Data chap. 2.2).

5. Residual risks
The system machine tool – chuck – workpiece is mainly influenced by the properties of the tool
(shape, weight, unbalance, material, etc.) as well as the cutting parameters which can cause
residual risks. Those remaining dangers must be considered by the worker and eliminated by
appropriate means.
6. Maintenance
Accurate and regularly maintenance (quarter annually) increases the natural life of the
SPANNAX® chuck. Please keep the following advices:
-Clean the chuck frequently, especially when changing the clamping head.
-Make sure the collet-carrier is clean and free of dirt and chips. Dirt reduces the run-out
accuracy and reduces the clamping force.
-Slightly greased collets increase the clamping force and reduce wear
-Do not use polar or ester-containing solvents to clean the spindle and the collet chuck.
Sealings and the rubber-bonded parts could be damaged.
-Avoid cleaning with compressed-air gun.
-On disassembly, check for cracks and other damages. Renew, if necessary.
-After a crash, a complete check is essential. You will find spare parts in chapter 4.3.
-Replace damaged parts only by original spare-parts. Otherwise guarantee is expired.
-Store the collet chuck clean and protect it from dust or similar influences. Spray it slightly with
anti-corrosion agent. Choose a dry place to store.
To provide long-term function and accuracy, depending on application conditions, it is
necessary to disassemble the chuck and to clean it completely. Check all parts for cracks or
damages. Regrease before reassembly.
Remember that your chuck should operate precisely and reliably.

5.1 Troubleshooting
Below, you will find some of the most frequently asked questions. If an error cannot be eliminated
with the methods below, please contact your technical support team. Always name the accurate
article-number and the description in case of questions or re-order.
Problem
Possible cause
Remedy
Radial run-out fault to
the workpiece
Chuck is not adjusted
properly or soiled
Adjust the chuck with a dial indicator. Mind to
tighten the mounting screws after adjusting
Axial run-out fault to
the workpiece
Dirt on the front plane to
the spindle
Unmount the chuck, clean, mount and
readjust
Shape-fault to the
workpiece
Workpiece is elastic
deformed during
clamping
Reduce clamping force, pay attention to
cutting force
Markings on the
clamping surface
Punctual or linear
workpiece clamping
Wide difference between clamping diameter
and collet bore. Eventually rework or regrind
the collet bore
Too low clamping
force
Wrong clamping head Mount suitable clamping head
Soiled chuck Disassemble the chuck, clean parts and
check for damages. Reassemble and
regrease.
Low hydraulic pressure Check the pressure to your operating
cylinder. Check for leaks. Increase pressure
Damaged operation
cylinder
Check operating cylinder for leaks and
damages. Replace sealings.
Workpiece not
clamped properly
Wrong switching position Dead-Length: Clamping occurs on pushing.
Switch machine control to: „I.D. clamping“
End-Stop and Through-hole chucks operate
on pulling: „O.D. clamping“
Clamping sleeve got
loose, relocation of
clamping position
Make sure, the safety screw is mounted and
not damaged.
