Abstract
A ball bearing has an inner ring and an outer ring defining inner and outer races respectively. A row of balls is provided between the races, and a cage holds the balls spaced apart from one another. The compartments of the cage are staggered alternately, so that adjacent balls engage opposite regions of the races to inhibit axial play.
Claims8
In a radial ball bearing having inner and outer bearing rings with an inner race and an outer race respectively, a plurality of balls in said inner and outer races and adapted to roll therein, and a cage for holding said balls spaced apart from one another;
- the improvement comprising means for holding said balls spaced from one another alternately in the axial direction of said bearing, whereby a first group of said balls engages one side of said inner and outer races and a second group of said balls engages the opposite side surfaces of the same said inner and outer races to inhibit axial play in said ball bearing.
In a single row ball bearing having first and second spaced apart bearing rings having first and second facing races respectively, a plurality of balls in said races, and a cage having separate compartments for receiving said balls and holding said balls spaced apart from one another;
- the improvement wherein the compartments of said cages are spaced alternately from one another in the direction transversely of the direction between said first and second races and transversely of the circumferential direction of said bearing, whereby a first group of said balls engages one side portion of said first and second races and a second group of said balls engages the other side portion of said first and second races and play of said bearing in said transverse direction is inhibited.
