Abstract
A high performance anti-friction bearing assembly for use in supporting a low torque stabilized platform as, for example, a gun platform mounted on aircraft, a ship or a land vehicle. The bearing assembly comprises three rings of forged alloy steel separated by two axially spaced rings of balls along elements of converging conical surfaces. The balls and their cooperating raceways have a conformity factor of approximately 0.59 and are pre-loaded against these raceways at a normally prevailing contact angle of 35.degree.. The high conformity factor together with various other design features provide a bearing for a stabilized platform operating at high efficiency with minimal torque losses under both simultaneous and non-simultaneous axial, radial and moment load conditions and associated distortio
