CMT#N

SPRING RETURN PULLING CYLINDERS IN STEEL

force: 10-100t
stroke: 25-50mm
max working pressure: 700bar

Features

Range in steel ( CMT###N### ).
They are threaded on the body, on the rod and in the base to mount the proper accessories. The internal and external nitriding treatment gives them a proper resistance to wear and corrosion.

Range in aluminium ( CMT###L### ).
Manufactured totally in aluminium (except the rod and the eyelets) these cylinders are characterized by their superficial anodizing treatment. They are equipped with a bellow in order to protect the rod, and from 30 tonne models they are also equipped with handles to ease their transport.

OPERATIONAL AREAS

Range in steel ( CMT###N### ).
Their use is suggested in situations where it is necessary to closen small masses in assemblies, in buildings and in laboratories to test the resistance of materials.

Range in aluminium ( CMT###L### ).
They are especially used in ship buildings and in steel structural works to pull together plates, or prefabricated parts which have to be welded together.

ACCESSORI :
– ZAS set of eyelets for series N cylinders

It’s important to drop the pressure inside the cylinder before disconnecting the quick coupler to avoid problems if re-inserting or  lowering the load. In case some pressure persists it is possible to use the apposite tool KTS38

The CMT cylinders accompanied with the PN pumps form a handy, simple and efficient set.
