RS PRO Alloy Steel Compression Spring 71mm Free Length, 14.5mm OD, 2mm Wire, 6.69 N/mm Spring Rate 121-264

The RS PRO 121-264 Alloy Steel Compression Spring is designed for demanding mechanical, industrial, and assembly applications requiring reliable force management and energy storage.

This precision-engineered compression spring measures 71 mm in free length and has an outside diameter of 14.5 mm, making it well suited for integration in constrained spaces and alignment with standard hardware. The wire diameter of 2 mm achieves balanced stiffness and resilience, while the spring rate of 6.69 N/mm ensures consistent compression-response for critical assemblies.

Crafted from robust alloy steel, the spring delivers long service life, strength, and effective load bearing. The square and ground ends provide excellent seating characteristics to minimize tilt, enhance stability, and simplify installation in guide rods or bores. With a minimum working length of 33 mm, the spring safely supports operational loads up to 253.99 N without permanent set or deformation.

Its compact proportions and precise force management make it an essential part for replacements, repairs, and new builds where tightly controlled mechanical response is critical.

Manufactured to meet DIN 2095 (grade 2) standards, this spring maintains dimensional and performance quality for reliable repetitive operation. The high-quality alloy steel material and closed-ground end type facilitate direct fitting on rods or within tubular housings for universal compatibility.

Applications include pen mechanisms, contact elements, actuators, vibration dampers, tensioners, and load-bearing fastener assemblies. This reliable RS PRO spring is a vital component in many engineering designs across industrial, laboratory, electronics, and automotive domains.
