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
Why BOSEN Ball Cages:
- Precision ground ball tracks for smooth, near-zero clearance movement
- High-speed capability above 45 m/min
- Available in multiple materials for different application needs
- Custom engineering support from drawing to finished part
- Private-label programs available (your brand, our quality)

A guide bush is used in combination with a guide pillar to ensure precise linear alignment between the upper and lower sections of a press die. It supports smooth motion and reduces side thrust, ensuring accurate part formation during each stroke. This precise alignment improves die life and enhances the quality of the formed components.
Common guide bush materials include hardened tool steel, sintered bronze, and high-strength alloy steel. For specialized needs, Oil-Free Guide Bushings are made with materials embedded with solid lubricants, allowing for self-lubrication and reducing the need for external grease or oil. Material choice depends on application requirements such as load, speed, and lubrication preferences.
Our products offer the high-presicion and quality ,Standard ISO or DIN guide bush, with standard product and customized drawings.
