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.
Specifications:
- Diameter: Φ12~Φ80 mm
- Material: Brass
- Steel balls: SKD61 (high wear resistance)
- Circlips included as standard
- Standards: ISO, DIN, or any European standard. Custom manufacturing to customer drawings also available.
- Production capacity: 3,000 pcs / monthly
Applications:
- High-speed stamping dies
- Precision progressive dies
- Long-stroke die applications
- Automotive stamping tools
- Electronic component dies
