Hollow Piston Cylinder

Description :

Hollow piston cylinders are single acting, spring return cylinders, suitable to use with hydropneumatic intensifiers. The piston is provided with a through hole.

Advantages :

Hollow piston cylinders can be easily adapted on existing fixtures. The cylinder can be mounted on the stud, by increasing the stud length. Automation can be achieved very fast.

Installation :

With the help of a back mounting plate, the hollow piston cylinder can be mounted on the stud as shown in fig.1. The cylinder can also be used to pull the stud, by mounting it on the other side of the base plate as shown in fig.2. For this arrangement, a wiper should be provided to the stud for 10 mm stroke cylinders.

Specifications :

Maximum operating pressure - 200 bar.
Return spring back pressure - @ 1 bar.

Notes :

As the cylinder is single acting, spring return, a breather is provided. It should be protected from cutting liquids and coolants.
For ordering the seal kit, add the prefix “S” to the cylinder part number.
