Associated Spring Raymond 205-105 Die Spring 1-1/4 in Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-105 is a red-coded die spring designed for use in tooling, stamping dies, and precision industrial applications. Built from chromium alloy steel with a trapezoidal wire shape, it delivers consistent force and controlled deflection under cyclic load conditions. The spring has a free length of 1.25 inches (32 mm), a rod diameter of 5 mm, and a hole diameter of 10 mm. With a maximum deflection of 9.60 mm and a spring rate of 99.93, the 205-105 provides predictable performance across its working range. It is manufactured to ISO 10243 standards and certified under ISO 9001:2008 and ISO/TS 16949:2009.

This die spring is intended for use in punch and die sets, molds, jigs, and fixtures where reliable return force is required. The red color coding indicates its load category within the ISO 10243 classification system, making it straightforward to identify and replace during tooling maintenance. It is suited for both OEM tooling builds and replacement in existing die sets. Machinists, tool and die makers, and maintenance technicians are the primary installers of this component.

Key Features

• Chromium alloy steel construction for durability under repetitive cycling
• Trapezoidal wire cross-section provides higher load capacity relative to round wire designs
• Red color code per ISO 10243 classification for quick identification
• Free length of 1.25 inches (32 mm) with a maximum deflection of 9.60 mm
• Spring rate of 99.93 for predictable, linear force delivery
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an ISO 10243-compliant replacement die spring for standard tooling applications requiring a 10 mm hole diameter, 5 mm rod diameter, and 32 mm free length in the red load category.

Installation Notes

Die spring installation and replacement should be performed by qualified tool and die makers or maintenance technicians with the press or tooling at rest and fully de-energized. Ensure the mating hole and rod dimensions match the spring specifications before installation to prevent binding or premature failure. Never compress a die spring beyond its rated maximum deflection, as overtravel causes accelerated fatigue and spring failure. Inspect the seating surfaces for wear or damage before installing a replacement spring.
