Dayton Lamina 6-2029-822 Ball Bearing Cage 2.5in Id

Product Description

The DAYTON LAMINA 6-2029-822 is an aluminum alloy ball bearing cage designed for use in precision die sets and punch press tooling. It retains and spaces ball bearings within a guide pin assembly, maintaining consistent alignment between die components during press operations. The cage measures 2.5 inches inner diameter and 7.25 inches outer diameter, with an overall length of 7.25 inches and a ring thickness of 0.375 inches. The distance before preload is 3.75 inches. Tool and die makers, press maintenance technicians, and mold shop personnel are the primary installers of this component.

This ball bearing cage is suited for die set guide pin assemblies in stamping, punching, and forming operations. It is commonly installed in both production and prototype tooling where smooth, repeatable ram guidance is required. The aluminum alloy construction keeps component weight low while providing adequate strength for the retention and spacing function within the guide pin and bushing assembly.

Key Features

• 2.5 inches inner diameter fits corresponding guide pin assemblies
• 7.25 inches outer diameter with 7.25 inches overall length
• Ring thickness of 0.375 inches for structural rigidity within the cage assembly
• Distance before preload of 3.75 inches for proper bearing engagement
• Aluminum alloy construction reduces weight while maintaining dimensional stability
• Sold individually (quantity of one per package)

Compatibility

Designed as an OEM-style replacement ball bearing cage for die set guide pin assemblies requiring a 2.5 inch inner diameter cage with 7.25 inch outer diameter and 7.25 inch overall length.

Installation Notes

Installation is typically performed by tool and die technicians or press maintenance personnel. Before servicing a die set, ensure the press ram is fully seated, the press is locked out, and energy is isolated per applicable lockout/tagout procedures. Handle aluminum alloy cage components with care to avoid nicking or deforming the bearing contact surfaces, as damage to these surfaces can affect bearing retention and die alignment. Verify correct cage orientation and preload distance per the die set manufacturer specifications before returning the assembly to service.
