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 racew

A heavy-duty anti-friction bearing assembly suitable for use in supporting a stabilized platform or the like with minimal torque losses under simultaneously-occurring axial, radial and moment loads, comprising: first, second and third annular forged alloy steel rings; said first ring having an annular radial flange provided with a pair of arcuate raceways located one on either side of said radial flange; said second and third rings including fastener means for clamping the same rigidly assembled axially of one another concentrically of said radial flange of said first ring, said second and third rings each having an arcuate raceway facing toward and spaced from a respective one of the arcuate raceways of said first ring; a separate ring of pre-loaded balls located between the raceways of said first and second rings and the adjacent raceway of said pair of raceways on said first ring; each of said raceways extending over an arc of substantially 90°and said balls and said raceways having a conformity constant of approximately 0.59; and each of said rings of balls including a plurality of elongated cage ring segments arranged in end-to-end spaced apart relation and each provided with a plurality of openings each loosely accommodating a single one of said balls, said cage segments for each ring of balls lying in oppositely converging conical surfaces.
