Associated Spring Raymond 104-148 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-148 is a medium heavy-duty die spring designed for use in tooling, stamping dies, and precision mechanical assemblies. It features a 0.375 inch hole diameter, a 3/16 inch rod diameter, and a 12 inch free length. The trapezoidal wire shape delivers consistent load performance and long cycle life under repeated compression. With a maximum deflection load of 40 pounds and a spring rate of 8.00 pounds per inch, this spring provides controlled, predictable resistance for demanding industrial applications. It is manufactured from chromium alloy steel for durability under high-cycle conditions.

This die spring is suited for press tooling, injection molds, stamping dies, and similar precision-force applications in manufacturing and fabrication environments. The red color coding identifies it as a medium heavy-duty spring per standard die spring color conventions. It is typically installed by tool and die makers, machinists, or maintenance technicians working on press and mold equipment. The 12 inch free length accommodates applications requiring extended travel or higher preload setups.

Compatibility

Designed as a standard die spring replacement for press tooling, stamping die assemblies, and precision mechanical fixtures requiring a 0.375 inch hole diameter and 3/16 inch rod diameter with a 12 inch free length.

Installation Notes

Installation is typically performed by tool and die makers or qualified maintenance technicians. Always relieve all press or clamping pressure before removing or installing die springs. Inspect the mating rod and bore dimensions to confirm clearance before installation. Ensure the spring is fully seated and aligned with the rod and bore to prevent lateral loading during operation.
