Gardner Spring 36053G Precision Compression Spring

Product Description

The GARDNER SPRING 36053G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It features a 0.3 inch outside diameter, a free length of 1.5 inches, and a wire diameter of 0.0421 inches. The spring delivers a rate of 20 pounds per inch with a maximum working load of 16.25 pounds. Closed and ground ends provide consistent seating and load transfer. This part is suited for mechanical assemblies, tooling fixtures, valve mechanisms, and similar applications where repeatable spring force is required. Technicians and assemblers working in HVAC, plumbing, electrical, and general industrial equipment will find this spring meets tight dimensional tolerances.

The 36053G is appropriate for use in light-duty compression applications across residential and commercial equipment. Its compact geometry, with a solid height of 0.673 inches and a hole diameter of 0.312 inches, makes it suitable for close-clearance installations where space is limited. The plain silver finish indicates no additional coating, which is typical for interior mechanical assemblies not exposed to corrosive environments. This spring is sold in packages of 5 units minimum.

Key Features

• Closed and ground ends for flat, stable seating on both surfaces
• 20 pounds per inch spring rate for predictable, linear deflection
• 16.25 pound maximum working load
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Solid height of 0.673 inches limits over-compression in confined assemblies
• Plain finish - no coating to interfere with dimensional fit

Compatibility

Designed as a precision replacement or new-installation compression spring for mechanical assemblies requiring a 0.3 inch OD, 1.5 inch free length, and 20 pounds per inch spring rate. Verify bore diameter clearance against the stated hole diameter of 0.312 inches before installation.

Installation Notes

Install using standard hand tools; ensure the mating bore and shaft dimensions are verified against the spring OD and wire diameter before assembly. Power down or de-energize any equipment before accessing spring-loaded mechanisms. Avoid compressing the spring beyond its solid height of 0.673 inches during installation or operation. Consult applicable equipment service documentation for load and deflection requirements before substituting springs in safety-critical applications.
