摘要：
A double-acting hydraulic cylinder (20) for steering and/or self-centring axles which comprises a cylindrical jacket (21) provided with a first axial portion (A) in which at least a piston (240) slides axially, the piston (240) being fixed to a command rod (24) able to project axially out of the cylindrical jacket (21), and a second axial portion (B), in which a centring pad (40) of the piston (240) slides axially, in which the first axial portion (A) and the second axial portion (B) are axially separated by an abutting element able to define an abutting surface for the centring pad (40), wherein the abutting element comprises a cylindrical body (30) which exhibits an external diameter that is smaller than an internal diameter of the cylindrical jacket (21) and an internal diameter that is smaller than an external diameter of at least an abutting surface (41) of the centring pad (40) and which is inserted internally of the cylindrical jacket (21), so that a free end (31) thereof defines an abutment for the abutting surface (41) of the centring pad (40).
