Modular piston with high strength tensile joint and method of manufacture

摘要

A modular piston having a high tensile strength piston and rod connection produced without lubrication, weld splatter or other contaminants. The method produces an optimized joint from strength, concentricity and cleanliness standpoints. The parts are centered and connected in the same operation. With this connection an elastomeric bumper and bumper containment plate are retained in position for a complete assembly.
