Gardner Spring 36221G Precision Compression Spring

Product Description

The GARDNER SPRING 36221G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It features a 0.12-inch outside diameter, a 1.5-inch free length, and a 0.0161-inch wire diameter. The spring rate is 9.7 pounds per inch with a maximum working load of 5 pounds. The closed and ground end type provides stable seating and consistent force distribution. This spring is suited for use in mechanical assemblies, instrumentation, valves, and light industrial equipment where precise, repeatable spring force is required.

The 36221G fits applications calling for a small-diameter, high-precision compression spring. Its plain silver finish and music wire construction make it a standard choice in OEM assemblies, fixtures, and mechanisms across HVAC, plumbing, electrical, and general mechanical industries. The hole diameter clearance is 0.125 inches, making it compatible with guide pins of up to 1/8 inch. Sold in packages of 5 units per order.

Compatibility

Designed for use in mechanical assemblies requiring a precision compression spring with a 0.12-inch outside diameter and 1.5-inch free length; consult your assembly drawings or OEM specifications to confirm fitment before installation.

Installation Notes

Precision compression springs should be installed by qualified mechanical technicians or assemblers familiar with spring-loaded components. Power down and de-energize any equipment before disassembling spring-loaded mechanisms. Avoid overstressing the spring beyond its rated maximum working load of 5 pounds, as exceeding this value can cause permanent set or premature failure. Verify guide pin or hole diameter compatibility before installation to ensure proper seating and alignment.
