Aluminum ball cage
For designs sensitive to moving mass; weight reduction still requires retention-strength checks.

Polymer ball cage
For suitable light-load and temperature conditions; verify resin, lubricant and dimensional stability.

Surface treatments and finishes
-
Pocket deburring and retention checks
Finish pocket edges without changing ball retention or leaving abrasive residue.
-
Material-specific cage finishes
Metal and polymer cages need different processes; nitriding, plating or polishing is not universal.
Family-specific questions
Can a ball cage replace a plain bushing?
No. Cages retain balls between post and ball bushing; they are not plain sliding sleeves.
