PTM-Parallel Grippers are based on the rack-and-pinion
principle like our rotating actuators. (picture 2) This fact
allows for a compact design with small dimensions and low
weight while still offering a high grip force.
The rack and pinion design produces an even clamping
force over the whole range. The clamping jaws are
absolutly centered in each position. Shortest clamping
times are possible.
Each base jaw is connected tightly with one rack. This
creates the great advantage that the jaws are firmly guided
over the whole length of the gripper.
This long jaw guidance guarantees close tolerance, high
precission and long life.
It is possible to work with very long clamping fingers
without any problems.
This advantages are enhanced in the alternative -PSMUthe PTM-Parallel Gripper with u-shaped jaws.
Another option is the use of a spring in our Parallel
Grippers, model ZFS, to secure the grip force during air
pressure failure. With this it is possible to work only with
one air connection.
Our Multi Position Cylinders -ZMZ- offer as many as two
additional stops or additional strokes, which is very
important in case of space restrictions.
The „Attachment for centering“ guarantees an exact
exchange or a quick change position of the Parallel
Gripper.
