Abstract

A cylinder includes a cylinder body defining a cylinder bore. End caps close opposite ends of the cylinder body. A piston/rod assembly of the cylinder includes a piston portion and a rod portion. The piston portion is located in the cylinder bore and the rod portion extends outwardly of the cylinder body through at least one of the end caps and terminates at an end having a first interlocking member. The cylinder also includes an attachment member having opposite first and second ends. The first end of the attachment member has a second interlocking member for cooperating with the first interlocking member for attaching the attachment member to the end of the rod portion. The second end of the attachment member includes a mating feature for connecting the attachment member and thus, the rod portion to another part.
