Ball Cages for Guide Bushings - Brass, Groove, with Circlip

These ball cages are used inside guide bushing assemblies for large injection and die-casting tooling where smooth, repeatable sliding motion is required. In die set mechanisms such as automotive connector and bracket molds, the cage’s groove geometry and integrated circlip help maintain stable ball circulation, supporting consistent alignment during repeated open/close cycles.

• Large die-casting tooling: Pair with DGBI3S/DGBI5S/DGBI7S guide bushing systems to preserve controlled motion under frequent load reversals.
• High-cycle production molds: Brass/steel cage construction helps retain dimensional stability while supporting reliable ball guidance over long runs.
• Long stroke guide layouts: The available cage length L = 24–240 mm allows matching different guide spans without compromising retention.

This variant is suited because it is specifically intended for the DGBI3S, DGBI5S, and DGBI7S ball-guide architecture, with circlip retention to reduce ball migration risk.

This series is offered as a brass cage and a steel cage (brass/steel cage family), targeting balanced performance between wear resistance and dimensional stability in guide bushing service. Brass is typically selected when smoother sliding and stable dimensions are prioritized in systems where balls circulate under controlled loads.

• Brass cage: Good bearing behavior for ball guidance; favors stable operation where surface finish and running smoothness are critical.
• Steel cage: Higher structural robustness for applications requiring greater mechanical stiffness and long-term dimensional retention under heavier duty cycles.

Heat treatment and hardness values are not provided in the supplied data; therefore, selection should be based on whether your die set load profile and wear expectations favor the brass vs. steel cage variant. For hardness and wear-critical designs, request the specific material/process documentation for the chosen cage option before final qualification.

To select the correct cage, start by matching the diameter D and overall length L to your guide bushing system geometry. This series covers D = 12–80 mm and L = 24–240 mm, so choose the variant that fits the guide bushing’s internal cage envelope and stroke requirements.

• Match D: Select the cage diameter within 12–80 mm so the cage groove profile aligns with the ball path in your DGBI3S, DGBI5S, or DGBI7S assembly.
• Match L: Use the required 24–240 mm cage length to span the active guide region and maintain correct ball spacing along the guide.
• Verify ball count: Confirm the available Number of Balls = 64–1472 matches the designed ball layout for your guide bushing to avoid under/over-loading of the race.

Tolerances are not specified in the provided data; consult your bushing design drawing for fit requirements. If multiple sizes are candidates, prioritize the exact D and L dimensions that align with the guide bushing cavity/core and the calculated ball count.
