ISO 10243 Extra Strong Rectangular Compression Springs (Yellow)

Engineered for the most demanding high-force applications, these rectangular section compression springs comply with ISO 10243 (EH) standards, delivering exceptional strength and reliability under extreme loads. The bright yellow color code provides immediate visual identification of the extra-strong spring rate, ensuring correct selection and preventing installation errors in critical systems.

Featuring rectangular wire construction, these springs offer superior stability and the highest load capacity in their class, outperforming equivalent round-wire springs where space constraints exist. Manufactured from premium alloy steel and subjected to specialized heat treatment, they exhibit exceptional resistance to fatigue, shock loads, and stress relaxation, even under continuous heavy-duty cycling.

Primary Applications:

• Heavy-duty ejection systems in large plastic injection molds and die-casting equipment

• High-tonnage stamping dies and metal forming presses

• Mining, construction, and agricultural machinery components

• Industrial brakes, clutches, and safety locking mechanisms

• Robust automation systems requiring extreme force reliability

These springs represent the ultimate solution for engineers seeking maximum force generation and durability in the most challenging operational environments, combining standardized precision with uncompromising performance for critical industrial applications.
