In accordance with one aspect of the present disclosure, a suspension strut for use on a work machine is provided. The suspension strut may have a forged one piece cylindrical inner housing that includes a hollow rod which forms a circumferential piston at an open end and a lower clevis at a closed end of the hollow rod. The suspension strut may further have a forged one piece cylindrical outer housing that includes a hollow barrel having an interior and an exterior surface, a closed end that forms an upper clevis, an open end, and a port on an outside surface of the hollow barrel. Further, the inner and outer housing may be coupled by a disk shaped end cap attached to the open end of the hollow barrel having an inner diameter that is slideably engaged with an outer surface of hollow rod.

An industrial gas spring with a pressure chamber in a casing with an end wall, a piston rod received at least in part in the casing for reciprocation between extended and retracted positions and a pressure relief assembly carried by the end wall. The pressure relief assembly may have a membrane communicating with the pressure chamber and a plunger configured to breach the membrane when engaged and moved by the piston rod when it overtravels its design intended retracted position.

An air bleed system for a suspension fork or shock absorber includes: a fluid passage between an interior of the suspension and an exterior of the suspension; and a manually operable valve having a first position substantially closing the fluid passage and a second position allowing fluid flow between the interior and the exterior.

An accumulator for a vehicle suspension damper, which includes an outer shell with an open end that connects to an accumulator port on the damper and a distal end, opposite the open end, which includes an end wall that extends radially inward to a gas charging port. A bellows assembly, which includes an annular bellows wall extending between proximal and distal plates, is positioned inside the outer shell to define a pressurized gas chamber inside the accumulator that is arranged in fluid communication with the gas charging port. The gas charging port includes a stem that extends inwardly from the end wall of the outer shell and the distal plate of the bellows assembly has an inner diameter that is received on the stem. The inner diameter of the distal plate is coupled to the stem of the gas charging port by a fixation component.
