Romheld - Model B1.7441 Series -Hollow-piston Cylinders

Hollow-piston cylinders are especially suitable for clamping workpieces that have a through hole or opening. The piston has a through hole with an internal thread. In connection with a standard tie rod and C-washer combination a variety of applications is possible (see application examples). After the workpiece has been inserted and centred by hand, the C-washer can be pushed onto the tie rod and then clamped hydraulically. Compared to mechanical clamping with clamping screws this has significant advantages: The clamping force can be hydraulically adjusted with precision and high repetitive accuracy. The operator can fully concentrate on the correct position of the workpiece. A significant time saving.
