A hydraulic double-acting cylinder has a body in which pistons are placed, with rods, and a mechanism for synchronization of motion of pistons installed in guide ring. Synchronization mechanism is arranged as nuts fixed on the rods and a shaft with screw threading at the ends, this is installed coaxially with respect to the body with possibility of rotation in the guide ring and interacts through screw threading with nuts. In the body a hollow cylindrical insert is coaxially fixed, at its outer surface a circular stop lug is provided. The pistons with rods are made hollow and are placed in circular cavities formed by the body and cylindrical insert with circular stop lug and the guide ring is fixed on the outer surface of the cylindrical insert.
