The larger eccentricity of pitman shaft provides a motion that forces the material to the bottom of the jaw plate. Spherical, self-aligning roller bearings, straight-bore pitman bearings and tapered-bore body bearings provide maximum strength to the pitman shaft and bearings for a long extended maintenance life.

Hi, I am trying to select an alternative material to be used for a shaft that is currently made of H13 steel. The service requirements are that the shaft is exposed to an operating environment of 300-400C (about 572F-752F) with cooling water inside the shaft cooling the shaft as it creates torque attached to a motor, which is operating inside an industrial scale coffee roasting machine.

Shaft Materials Shafts are commonly made from low carbon, CD or HR steel, such as ANSI 1020–1050 steels. Fatigue properties don’t usually benefit much from high alloy content and heat treatment. Surface hardening usually only used when the shaft is being used as a bearing surface. Shigley’s Mechanical Engineering Design

The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly. The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber.

– Start with an inexpensive, low or medium carbon steel for the first time through the design calculations. If strength considerations turn out to dominate over deflection, then a higher strength material should be tried, allowing the shaft sizes to be reduced until excess deflection becomes an issue.
