The V260CF are double-acting hydraulic cylinders with a mechanical locking system of the rod in the end stroke position (extended rod), which permits to contrast very high opposite thrusts.
Such a solution is widely applicable in the field of plastic injection and die-casting molds, in order to stand the injection pressure on large molding surfaces.
The rod is hydraulically unlocked automatically when the piston comes back. WARNING: - For a correct functioning the cylinder it’s necessary to complete all the times the total available cylinder stroke, both forward and backward, in order to assuring the locking on one side and to avoid hammer-effects on piston-rod screw on the other side. For a firm locking it is necessary to keep the oil in pressure, when pushing, at a minimum of 120 bar-1740 PSI.- Pay great attention to the traction force, which is considerably lower than the thrust. - Before making a drawing of an application, pay attention on Pre-load notes stated at page F5.
