Commercial Shearing, Inc.

Ingo Friedrichs

A motor or processing machine, such as a lowspeed radial piston motor, having a piston with a socket formed therein operatively contacting a ball formed on one end of a piston rod, to form a ball-and-socket joint with articulated movement, and a shoe on the other end of the piston rod, adapted to glide on a rotating element of the machine, such as a crankshaft eccentric, in which the entire piston rod is formed from a bronze-base bearing metal, such as steel bronze. At least the shoe of the piston rod may be coated with a thin, soft run-in layer, such as tin, and a pocket may be formed in the shoe of the piston rod to provide hydrostatic relief.
