PowerMax cam unit SN5650-PMU-0330 — SN5650-PMU-1200
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 Power Max 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.
Attention:
If attachments are removed during the assembly process, they must be secured again with
Loctite 242.
Notes on tightening torques:
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:

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 cam retainer is between the
marking of the body , the whole cam is not driven back
in the correct initial position.
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 Power Max
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.
