Abstract: A trunnion bearing has a generally cylindrical trunnion member that defines two inner ring raceways. A mounting pin is disposed within the trunnion member and an outer ring encircles the inner ring raceways. The outer ring defines raceways that are aligned with respective inner ring raceways. There is a row of balls between each inner ring raceway and a respective outer ring raceway. A bearing is assembled by placing a mounting pin within a trunnion member. An outer ring having raceways on its interior surface is placed eccentrically around the trunnion member. Each outer ring raceway is aligned with an inner ring raceway. The eccentricity creates an insertion opening for balls. Balls are inserted between the inner ring raceways and their respective outer ring raceways via the insertion opening. The balls are distributed around the trunnion member, and the outer ring moves into concentric relation with the trunnion member.

Abstract: In a rotary wing aircraft tail rotor head assembly having a ball bearing on a spindle at the head of a rotor wing, the ball bearing contains slug ball separators between the balls in the bearing. The separator may be made from PEEK, PTFE, or polyimide. The ball-to-ball separation between two balls of like diameter provided by the separator may about 3.2 to about 64% of the diameter of one of the balls. A separator may have an annular configuration that defines a passage therethrough, the passage having two ends and the interior of the separator being tapered to define a maximum diameter at each end and a minimum diameter therebetween. The taper of the chamfered surface of the slug ball separator may define a conical angle of about 75° to about 120°. A ball bearing as described herein may also be used in a rotary wing aircraft swashplate having a stationary plate, a rotating plate; and a thrust bearing between the stationary plate and the rotating plate.
