Dayton Lamina 12-40 Spring Cage 1.5in Od 5in Oal

Product Description

The DAYTON LAMINA 12-40 is a steel spring cage designed to guide and retain die springs in punch press and stamping tooling applications. With an outside diameter of 1.5 inches and an overall length of 5 inches, this cage provides consistent spring alignment under repeated cycle loads. Steel construction offers the durability required for sustained use in metal fabrication and progressive die setups. Toolmakers and die maintenance technicians are the primary installers for this component.

This spring cage is used in die sets where spring guidance and containment are critical to tool performance. It is suited for applications in stamping, forming, and blanking dies found in both job shop and production environments. The 1.5 inch OD fits standard spring pocket bores in common die set configurations, making it a practical replacement or new-build component for tooling assemblies.

Key Features

• 1.5 inch outside diameter for compatibility with standard spring pocket bores
• 5 inch overall length provides adequate spring travel and containment depth
• Steel construction for durability under cyclic press loads
• Guides and retains die springs to prevent lateral displacement during operation

Compatibility

Designed as an OEM-style replacement or new-build component for die sets requiring a 1.5 inch OD spring cage in punch press and stamping tooling applications.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die build or repair. Power down and lock out all press equipment before servicing any tooling assembly. Ensure the spring pocket bore diameter and depth are confirmed against the cage OD and OAL before pressing or seating the cage. Follow all applicable shop safety procedures for press tooling work.
