Associated Spring Raymond 105-112 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-112 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and precision tooling applications. It features a trapezoidal wire cross-section, which increases the load-bearing surface area compared to round wire designs, allowing it to handle a maximum deflection load of 37.8 pounds within a maximum deflection of 0.9 inches. Constructed from chromium alloy steel and finished in gold to indicate its heavy-duty rating, this spring delivers consistent force characteristics across its 3-inch free length. Toolmakers, die setters, and maintenance machinists install this component in production tooling environments.

This spring is sized for applications requiring a 3/8-inch hole diameter and a 3/16-inch rod diameter. It is suited for heavy-duty stamping and forming die sets where controlled spring return force and repeatable deflection are required. The 3-inch free length makes it appropriate for die assemblies with moderate to compact stack heights. The gold color coding follows industry-standard identification conventions for heavy-duty die springs, simplifying spring selection and replacement on the shop floor.

Key Features

• Heavy-duty rating with a maximum deflection load of 37.8 pounds
• Trapezoidal wire shape for increased load capacity relative to wire cross-section
• Chromium alloy steel construction for durability under cyclic loading
• Gold color coding identifies heavy-duty duty class at a glance
• Spring rate of 41.00 pounds per inch for predictable force behavior
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-installation die spring for heavy-duty stamping and forming die assemblies requiring a 3/8-inch hole diameter and 3/16-inch rod diameter with a 3-inch free length.

Installation Notes

Die springs are installed by toolmakers or die maintenance technicians following lockout/tagout procedures before any press or tooling work begins. Ensure the mating hole and rod dimensions match the spring specifications before installation. Do not compress the spring beyond its rated maximum deflection of 0.9 inches, as exceeding this value will reduce service life and can cause premature failure. Inspect seating surfaces for burrs or damage that could cause uneven loading across the spring coils.
