Abstract
A pneumatic actuator is operable between an extended condition and a collapsed condition, and is capable of displacing a workpiece during movement between the extended and collapsed conditions. The pneumatic actuator can include a flex member (202) and a mounting base (204). The flex member can include a flexible wall (208) with a mounting bead (222). The mounting base can include a base portion (266) and a bead portion (268), and can be operatively connected along the flex member such the mounting bead is at least partially captured between the bead portion and the base portion. In this manner, a substantially fluid-tight seal can be formed and an actuator chamber can be at least partially defined between the flex member and the mounting base. An actuator support pad can receive and abuttingly engage at least a portion of the pneumatic actuator. A method of assembly is also included.
