description An air bladder actuated railroad car retarder is designed to simplify installation, operate in a manner imposing minimal stress on the bladder, improve preventive maintenance, and simplify access to the main fulcrum bearings. The air bladder actuator is made with lightweight aluminum end plates and utilizes a unique stud assembly for attaching the actuator to the retarder pivot arms. Rigid mounting of the air bladder with a unique pivot geometry exposes the bladder to minimal lateral deflection which is balanced in both directions. A simple stroke limiter assembly, external to the air bladder, is also used to measure and monitor wear of the main fulcrum bearings. The stroke limiter assembly is easily demountable and removable to enhance access to the main fulcrum pivot for replacement of the fulcrum bearings.
