The lid is mounted around a roller.
Protective bushings with specially treated surfaces protect bearings in rolling bearings.
An integrated rod offers considerable durability and allows for easy maintenance.
A hydraulic cylinder moves upwards by hydraulics and downwards by its own weight.
A roller attached to a rod rises about 2mm above the surface of the pin and the die moves upwards
