Gardner Spring GE0300-0552250S Extension Spring 0.3in Od

Product Description

The GARDNER SPRING GE0300-0552250S is a stainless steel extension spring engineered for reliable tensile force applications across mechanical, industrial, and HVAC equipment assemblies. It features a 0.3 inch outside diameter and a 0.055 inch wire diameter, with a spring rate of 24.07 lb/in and a maximum work load of 18.8 pounds. The free length measures 2.25 inches, extending to a maximum of 2.95 inches. This spring is supplied in a pack of 3 and is specified by maintenance technicians, equipment assemblers, and trade professionals performing precision mechanical work.

This extension spring is suited for residential and light commercial applications where a compact, corrosion-resistant tensile spring is required. Typical uses include damper linkages, access panel latches, equipment door assemblies, and mechanical actuator return mechanisms. The plain stainless steel finish provides resistance to moisture and mild chemical exposure, making it appropriate for both indoor and outdoor service environments where carbon steel would be prone to corrosion.

Key Features

• Stainless steel construction with plain finish for corrosion resistance
• Spring rate of 24.07 lb/in for consistent, predictable tensile force
• Maximum work load of 18.8 pounds
• Initial tension of 1.67 pounds to maintain coil closure at rest
• Compact 0.3 inch outside diameter fits tight clearance installations
• Sold in a quantity of 3 pieces per package

Compatibility

Designed as a direct-specification extension spring for mechanical assemblies requiring a 0.3 inch OD, 0.055 inch wire diameter, and 2.25 inch free length in stainless steel construction.

Installation Notes

Installation should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. Always de-energize and relieve any stored mechanical tension in the assembly before removing or installing extension springs. Use appropriate pliers or spring hooks rated for the load to avoid uncontrolled release. Ensure the hook engagement points are fully seated and undamaged before returning the assembly to service.
