Precision Ball Cages for High-Speed Stamping & Die-Casting Dies
Ball cages (also known as ball retainers or steel ball bushings) provide rolling guidance for stamping and die-casting dies. The steel balls recirculate within the cage, reducing friction and enabling high-speed operation above 45 m/min — significantly higher than conventional sliding guides.
