Hoover's ability to hold close tolerances on a production run of balls is synonymous with dependable performance. It is one of the reasons that Hoover balls are found in the majority of America's automotive. aircraft, marine, industrial, construction and scientific applications. Hoover manufactures balls in sizes from 17-thousandths of an inch diameter for use in ball point pens, to 4 1/2 inches in diameter for use in heavy duty military and industrial applications.
Tolerances are held to within 25-millionths of an inch for bearing-quality lapped balls, and to within 3-millionths of absolute roundness for precision balls. Surface finish is less than one RMS. The production of balls is a complex time-consuming and exacting process; a process that historically has been based upon the skill of the operator. Hoover combines this operator skill with ongoing research and development program designed to infuse the manufacturing process with the latest in scientific development and technology.
