Powder Metal Pulley Hub

This part was chosen to be profiled to illustrate the excellent machinability of PM when the correct materials are chosen.

The Driver Pulley Hub began as a pressed and sintered Ø 1.750" OD X 2.875" long cylinder with a Ø 0.750" X 1.750 deep keywayed ID. At this point it was given to the machine shop for completion. A Ø 1.250" X 1.190 body was first machined on its closed end. That was then machined into a 3/4 - 14 threaded detail. Two holes were drilled through its OD into the center hole and #10-32 threaded.

With all of this secondary work the part still provided a significant cost reduction over its machined bar stock option.

Engineers at Ridgway Powdered Metals are eager assist its customers in the design of their custom PM components. RPM Engineers and/or its Sales Representatives can consult with customers about the most economical way to produce accurate, high quality parts with the required dimensions, tolerances and geometry.
