The American Society of Mechanical Engineers
The American Society of Mechanical Engineers The American Society of Me- chanical Engineers designates the first Kingsbury thrust bear- ing at Holtwood Hydroelectric Station as an International His- toric Mechanical Engineering Landmark on June 27, 1987. The Kingsbury bearing at Holtwood There’s an invention that’s been working for 75 years along the Susquehanna River in Lancaster County, Pa., with negligible wear, while withstanding a force of more than 220 tons. The Susquehanna Section of the American Society of Mechanical Engineers dedicated that invention — a 48-inch-diameter thrust bearing — on Saturday, June 27, 1987, as its 23rd International Historic Mechanical Engineering Landmark. The diagram at left is taken from a sketch by Kings- bury himself, showing his insight into the pressure The bearing is the brainchild of the late distribution in an offset bearing shoe.

Holtwood today is owned and operated by Pennsylvania Power & Light Co. It was built and operated until 1955 by Pennsylvania Water & Power Co.
