ISO 10243 Medium Rate Rectangular Compression Springs (Blue)

Designed for applications demanding reliable, medium-force compression, these rectangular section springs are manufactured in compliance with ISO 10243 (M) standards, ensuring precise dimensional and performance consistency. The distinctive blue color code provides immediate visual identification of the medium spring rate, streamlining selection and preventing errors in assembly.

The rectangular wire construction offers superior stability and a higher load-bearing capacity within a compact footprint compared to equivalent round-wire springs. Crafted from high-carbon steel or alloy spring steel, they undergo rigorous heat treatment to deliver exceptional fatigue resistance and long service life under continuous cyclic loading.

Primary Applications:

• Mold & Die Industry: Ideal as ejector springs in plastic injection molds, die casting molds, and stamping dies.

• Automotive Systems: Used in clutches, brakes, valves, and suspension components.

• Industrial Machinery: Applicable in presses, jigs, fixtures, and hydraulic valves.

• Heavy-Duty Appliances: Suitable for high-stress mechanisms in agricultural and construction equipment.

These springs are indispensable press-fitting components for engineers and manufacturers seeking robust, predictable force and durability in demanding industrial environments.
