POSITIVE CLAMPING CYLINDERS WITH HOLLOW PLUNGER
The series 400 provides a clamping force without permanent connection to a hydraulic power source.
The force is provided by built-in packs of Belleville washers, and the hydraulic connection is only required to compress the springs and return the piston.
These cylinders are ideal for clamping guides, dies or pallets, and in all cases where permanent hydraulic connection would require complex circuits.
A central threaded through hole allows use in push or pull mode.
Special versions can be produced on request.
