Hollow Piston Cylinder
Single-acting, with spring return
- flat and compact design
- steady piston movement
- stroke limited even with max. working pressure
- rapid and easy retrofit
The Hollow-piston cylinder is for the press bed and ram, in connection with tie rods, screws and threaded rods, for clamping and locking dies on presses and machines.
It can be attached, screwed or flange-mounted in any position. The clamping force is built up by applying pressure to the piston and the piston is returned by a spring. The piston is provided with a through hole and is hardened and ground. The housing is made from heat-treated steel and its surface is burnished.
The Hollow Piston Cylinder is part of the Hilma Quick Die Change System solutions and helps manufacturers accomplish their goals in shortening die change time and making facilities more productive and profitable. To survive in today’s competitive worldwide market, manufacturers are reducing inventory costs by running smaller batch sizes and making shorter production runs. One way to maximize press uptime in an environment like this is to implement faster more effective die changes.
