Dayton Lamina 6-2429-822 Ball Bearing Cage 3 in Id

Product Description

The DAYTON LAMINA 6-2429-822 is a ball bearing cage designed to retain and guide ball bearings within die sets and precision tooling assemblies. It maintains consistent ball spacing under cyclic loading, reducing friction and wear between mating die components. The cage features a 3-inch inside diameter and a 7.25-inch outside diameter, with a ring thickness of 0.375 inches and a distance before preload of 3.75 inches. Die makers, tool and die technicians, and press shop maintenance personnel typically specify and install this component in stamping and forming operations.

This ball bearing cage is suited for use in die set assemblies where controlled ball retention and accurate guidance are required. It is commonly installed in progressive dies, blanking dies, and forming dies found in metal stamping facilities. The 3-inch ID sizing positions it for medium-to-large die sets where load distribution across the bearing surface must remain uniform throughout press stroke cycles.

Key Features

• 3-inch inside diameter for consistent fit within compatible die set guide posts
• 7.25-inch outside diameter provides broad bearing surface coverage
• Ring thickness of 0.375 inches contributes to structural rigidity under press loads
• Distance before preload of 3.75 inches allows proper seating in the die set assembly
• Weighs 1 pound for ease of handling during die setup and maintenance

Compatibility

Designed as an OEM-style replacement or direct-fit component for ball bearing die sets requiring a 3-inch ID ball bearing cage with a 7.25-inch outside diameter.

Installation Notes

Installation of this cage is typically performed by tool and die technicians during die assembly or scheduled maintenance. The die set should be fully removed from the press and all stored energy released before disassembly. Verify that the guide post and guide bushing surfaces are clean and free of burrs before seating the cage. Do not force the cage into position; confirm that the inside diameter and outside diameter measurements match the existing die set specifications before installation.
