Features
All COF cylinders are supplied with a smooth hollow saddle and have a threaded body, rod, and base to facilitate the fixing and inserting of the necessary accessories. These cylinders are equipped with a safety valve, which is connected to the retract chamber and prevents any possible overpressure. The end of the stroke nut has a wiper to prevent the entrance of dirt.
The nitride anti-corrosive treatment makes them suitable for work in harsh environments and in the open air.
Operational Areas
The through hole makes them particularly suitable for tensioning, mounting, and the extraction of pulleys, bushings, and heat exchanger pipes. They can be used in pushing and pulling operations by putting a bar or a cable attached to the saddle.
