[1] Kingsbury is most famous for his hydrodynamic thrust bearing which uses a thin film of oil to support weights of up to 220 tons.
[2] Albert Kingsbury was born in Morris, Illinois and graduated from Cuyahoga Falls High School, OH in 1880.
In addition to his interest in tribology and bearings, Kingsbury enjoyed the world of arts, history, and letters.
Kingsbury died in Greenwich, Connecticut 1943, and is buried at the Green-Wood Cemetery, Brooklyn, New York.
[1] Kingsbury resumed his formal education at Ohio State University, but he again dropped out to work as a machinist with the Warner and Swasey Company in Cleveland.
Working under Professor Thurston, Kingsbury conducted tests on bearing materials for the Pennsylvania Railroad.
[1] His craftsmanship, honed by his experience in machine shops, allowed Kingsbury to fit half-bushings to the journal by scraping.
During his time at the University of New Hampshire, he created an innovative test machine to measure friction in coarse pitch, lubricated screw threads at loads of up to 14,000 psi.
[1] The usefulness of this invention received mixed reviews from the American Society of Mechanical Engineers (ASME).
Kingsbury joined the Worcester Polytechnic Institute to continue pursuing his interest in lubrication.
[1] He secured expansions for laboratory facilities and funding to continue his tests on a centrally pivoted thrust bearing with the aid of his students.
By recognizing the analogy in the equations for lubrication and those for electrical flow in a conductive fluid and variable depth, Kingsbury was able to make complicated predictions of slider load capacity well before the advent of computers.
[7] Later work by Hardy and Doubleday showed that this property was related to the ability of polar lubricants to adsorb and form close-packed monolayers on the sliding surfaces.
[8] for his wide-ranging contributions to the field, Kingsbury was named as one of the 23 "Men of Tribology" by Duncan Dowson.
