Abstract: A piston rod, having a threaded end, is threadedly received in a split collar which is (a) internally threaded and (b) externally tapered. The collar is received in a tapered bore formed in a cross-head. The crosshead has a plurality of threaded holes formed therein to receive studs which penetrate a pressure plate. Nuts secured to ends of the studs draw the plate against the collar to cause its threads to fully engage the threads of the rod end, and secure the collar in place. The rod, of course, can be turned in the collar, threadedly to adjust its axial positioning in the collar.

Abstract: A piston assembly may include a piston rod and a piston disposed on the piston rod. The piston may include a frame end cap defining a through-bore for receiving the piston rod, and the frame end cap may form a first end of the piston. The piston may include an outer end cap defining a through-bore for receiving the piston rod, and the outer end cap may form a second end of the piston. The piston may also include a center support defining a through-bore for receiving the piston rod. The center support may be disposed between the frame end cap and the outer end cap, and an outer surface of the piston rod and an inner circumferential surface of the center support may define a radial gap.
