3. Characteristics
The execution of this STRACK cam unit is a “side cam unit type SN5650”.
These cams can be mounted: - without mounting plate as “Basis” and “Medium” version
- with mounting plate as “Premium version”
These PowerMax cam units consists of:
- cam retainer
- cam body
- driver
with the corresponding accessories
All PowerMax cam units are equipped with gas springs.
In this system, nitrogen with a purity grade of ≥99.8 vol.-% is used as active fluid medium for the
gas springs.
The cylinder dimension, cylinder number and filling pressure (different at the diverse cam types)
determine the reset force which is available.
Please consider that all PowerMax cam units are the successful result of a long development work.
The resulting advantages optimally develop at the full exploitation of the respective cam stroke
during the work process; that means, the stamping- and benching operation of the cam unit should
be carried out in the front end position.
The complete exploitation of the cam stroke allows the maximal intervention of the active return and
the therewith connected highest possible supply of retracting- and stripper forces (about 10 % of the
pressing force).
In the front endpoint of the cam stroke there is the maximal retraction of the gas spring. Generally
applies: The construction and the resulting values, like assembly height and restoring forces, require
that the cam unit is mounted in the front end position.

5. Design of the PowerMax cams
STRACK NORMA PowerMax cams are produced in a high-precision manner.
The guidances which are grinded to a tight guide clearance allow highest loads. The cam units can be
equipped with the tool on the working surface. In doing so you have to consider that the force affects
in the centre of the working surface.
If you have an off-center load irregular forces
arise on the guidances and produce an increased
wear.
(See 3.1. description of the construction types)
Herefrom you can clearly read the maximal force outside the centre of activity for the x respectively the y
axis. Modifications of position which will be possible in future should be considered previously to choose a
cam size which corresponds to the force.
To be able to guarantee an equal running life, the load forces reduce, according to the position, on the
working face.
You will find detailed information in the catalogue indications concerning to your cam in the internet
under:
www.strack.de
Basis <750,000 strokes
Medium >1,000,000 strokes
Premium >1,000,000 strokes
Attention:
If the cam should be superstructed with accessories
a new calculation is necessary.
Please contact us.

6. Preparation of tool and press
Tool, press and peripheral devices have to be suited, prepared and adapted according to the indications
of STRACK NORMA for the utilisation of the PowerMax cam unit.
Drain off fluid (for example water or drawing compounds) well-directed by drainage. You have to take
care that punching wastes don’t fall in or on the cam guidance.
Cam slide and guidances can seize. Parts falling down can damage the guidances, hereby possibly the
running life of the cam reduces. If there is a failure, the cam slide can’t be placed back in the initial
position.
7. Shouldering
The force distribution of the individual forces in the cams depends on the right shouldering in the tool
and the cam angle.
If the heights h1 and h2 (see the picture below) reduce in the tool, the forces of the shouldering can’t
be completely absorbed.

8. Production
During the production no particular precautionary measures have to be taken, which exceed the valid
operating safety regulations paragraph 3.
Advice:
Please secure that the STRACK cams especially the gas springs are not dipped
in fluid.
If you are using for example aggressive drawing oils during the production, make
a controlled drain for them (drainage borings, cutouts and so on), so that the
fluids are directed away from the gas springs.
Thereby seal damages are avoided.
Tip:
Control the nitrogen pressure of the gas springs in regular intervals, to detect
changes in the pressure level in time. During maintenance works you have to
consider a correct return of the cam slide.
Advice:
The cam units are equipped with low-maintenance slide elements out of bronze
with solid lubricant. In normal case lubrication is not necessary.
A lubrication may only be effected in case of need with the following lubricants:

8.1.2 Handling with safety ring bolt (SN1594)
Beginning from the cam units 260, cam retainers and slides
can simplified be mounted together by means of the safety
ring bolt SN1594, because of the fact that the different
positions of the handling screwing thread facilitates the
mounting of the cam slide in the slide retainer.
By changing the position of the safety ring bolt,
the cam retainer and the cam slide can be simpler
mounted together into the tool.
Mounting of the cam retainer with the cam slide
in the tool with lateral thread for the flexible
mounting and turning of the cam.

8.2 Marking of the cams
All PowerMax cams are equipped with a type plate.
On this type plate the name and the serial number of the cam are lasered.
Name of the cam
6-digit serial number
For additional information
for customers
The serial number refers to all cams of an order and is different concerning order to order. The PowerMax
cams were adjusted in the company STRACK. For this the hardened steel gide strips were ground to the
corresponding dimension. The appropriate screws were additionally secured by the screw locking adhesive
Z9093.
Attention: Don’t remove the rails. If this should be inevitable in a case of a crash, the replacement strips
have to be adjusted again.
To avoid confusions within a series the assembly groups of the individual cams are marked within the series
with numbers of 1 to ... (see picture below). During the mounting please absolutely consider the right
coordination of the components to avoid problems.

Additional markings on slide retainer and slide body
make it possible to control the position of the cam in
the tool.
If the cam is moved together, the upper markings
correspond; if the cam is extended the lower markings
correspond.
If the marking on the slide body is between the markings
of the slide retainer, the whole cam is not driven back in
the correct initial position.
