Development of a pneumatic sensor for measuring the torque of instrument ball bearings
(Virginia Polytechnic Institute, 1968)
Of the studies that have been conducted on the operational characteristics of instrument ball bearings, a great majority have been in accordance with MIL-STD-206. Since tests in compliance with this specification determine ...
The measurement of the running torque of oil and grease lubricated instrument ball bearings under combined radial and axial loads
(Virginia Polytechnic Institute, 1966)
Although many studies have been made on the operating characteristics of instrument bearings, most were conducted at two rpm or less and with thrust load only. A study by H.H. Mable tested the running torques of radially ...
