These models of single-acting cylinders with spring return may be screwed straight into the equipment. The oil enters through ducts machined inside the unit and sealing is assured by means of seals on the bottom of the threaded hole.

Available in two versions: with crowned (version A) or threaded piston end (version B). A long piston guide in hardened steel combined with sealing by means of O-ring and backing ring ensures long cylinder lifetime. The body is also constructed in heat-treated steel for automatic machines.
