ISO 10243 Light Rate Rectangular Compression Springs (Green)

Engineered for precision applications requiring consistent, low-force compression, these rectangular section springs comply with ISO 10243 (L) standards for dimensional and performance reliability. Their distinctive green color coding provides immediate identification of a light spring rate, streamlining selection and inventory management in complex assemblies.

The rectangular wire design offers greater solid height stability and higher load capacity within the same space compared to round-wire equivalents, making them ideal for space-constrained environments. Manufactured from high-grade spring steel, they ensure excellent fatigue resistance and long-term durability under cyclic loading.

Primary Applications:

• Mold & Die Industry: Ejector springs in plastic injection and stamping molds.

• Precision Engineering: Actuation mechanisms, clutches, and safety valves.

• Automotive Systems: Sensors, actuators, and lightweight braking components.

• ConsumerAppliances: Electromechanical switches and damping systems.

These springs are essential press-fitting components for engineers seeking predictable, low-force performance and enhanced service life in demanding industrial settings.
