Title: Michael L. Blair and Axially Hardened Bearings.

Introduction

Michael L. Blair is an inventor associated with Keene, New Hampshire, and the company MPB. His work includes a patented method for making ball bearing assemblies more resistant to excessive axial loads.

Latest Patents

Blair is credited with 1 patent, titled “Method of Making Axially Hardened Bearings.” The invention describes assembling a bearing with races and balls, fixing one race axially, and applying a controlled axial load to the other race. While that load is applied, the races’ face surfaces are ground flush. After the force is released, a stop ring is positioned so that the first race rests against its stop face while the second race remains spaced from it under normal loading. If an excessive axial load is applied, the second race moves toward the stop ring, which then carries the load and helps protect the bearing from damage.

Career Highlights

The bearing method is designed to let an assembly withstand, while not operating, an axial load greater than the level that could otherwise damage it. The patent also describes a ball bearing assembly that can be formed using the method.

Collaborations

Keith M. Gordon is identified as Blair’s coworker. The available information does not specify whether Gordon collaborated on the bearing invention.

Conclusion

Michael L. Blair’s patented bearing method uses carefully controlled manufacturing and a stop ring to redirect excessive axial loads and help prevent bearing damage.
