Ball cages, also known as ball bearing retainers or separators, are crucial components in ball bearings..
Spacing the Balls: Cages keep the balls evenly spaced around the raceway, ensuring smooth and uniform load distribution. This spacing helps in
preventing the balls from colliding with each other, reducing friction and wear.
Retaining the Balls: They hold the balls in place within the bearing, maintaining their positions relative to the races. This retention is particularly important during assembly
and disassembly.
Reducing Friction: By maintaining proper separation and alignment of the balls, cages reduce friction between the balls and between the balls and the raceways, improving
the efficiency and longevity of the bearing.
Guiding the Balls: Some designs use the cage to guide the balls in their paths around the raceway, ensuring they move smoothly and consistently.
