RS PRO Alloy Steel Compression Spring, 22 mm Free Length, 9.25 mm OD, 8.92 N/mm Spring Rate 751-641

RS PRO 751-641 Alloy Steel Compression Spring is a precision-engineered mechanical component manufactured from premium alloy steel. Designed for industrial reliability, this compression spring features a 22 mm free length with a 9.25 mm outside diameter and a robust 1.25 mm wire diameter. The spring delivers a consistent spring rate of 8.92 N/mm, providing accurate force characteristics for demanding engineering and mechanical applications.

With closed-end construction, the spring allows easy integration into both rod and tube-based assemblies, ensuring firm placement and stable performance in machinery, valves, mobile devices, electrical switches, and automotive parts. Its minimum working length of 10.5 mm offers substantial range in compressed applications; at this minimum length, the spring supports a load of 104.93 N, enabling reliable energy storage and controlled release cycles for precise actuation.

Compression Springs such as this are vital in automation, instrumentation, and fastening systems where restoring force and energy storage are critical. The helical coil is manufactured with a right-hand helix and is squared and ground for wire diameters ≥ 1.00 mm, enhancing stability and longevity under repeated compression cycles. Alloy steel construction adds resistance to fatigue and corrosion, supporting extended service life in industrial and laboratory environments.

Typical applications include mechanical assemblies, ball point pens, vehicle mechanisms, mobile phones, valves, electronics, and switches. The spring’s versatility makes it suitable for manufacturing, maintenance, laboratory instruments, construction, water treatment plants, and commercial devices that require reliable compression and return force.

Dimensions and loading conform to DIN 2095 (grade 2), ensuring accurate technical standards are met for interchange and installation. Package contains a single compression spring for direct use in industrial projects and precision engineering tasks.
