Gardner Spring GT3528118-ML Torsion Spring 180 Deg

Product Description

The GARDNER SPRING GT3528118-ML is a steel torsion spring designed for mechanical assemblies requiring precise rotational force and angular deflection control. This spring features a 180-degree deflection angle, a 0.45-inch outside diameter, and a 0.035-inch wire diameter with 4 coils wound in a left-hand direction. The 1.071 in-lb torque at leg length makes it suitable for light-duty actuation mechanisms, return assemblies, and latching components. It is typically installed by mechanical assemblers, maintenance technicians, and trade professionals working on HVAC linkages, plumbing valves, and other mechanical equipment requiring torsional return force.

This torsion spring is suited for compact mechanical assemblies where space is limited and a defined rotational return force is required. The 0.281-inch rod size and 0.281-inch maximum tool size make it compatible with standard arbor-based installation tooling. With a 1.25-inch leg length and left-hand wind direction, this spring fits applications where counterclockwise preload or return motion is specified. Typical use cases include light equipment controls, actuator arms, door latches, and similar mechanisms found in residential and light commercial settings.

Key Features

• 180-degree deflection angle for half-turn rotational return applications
• Left-hand wind direction for counterclockwise torque loading
• 0.45-inch outside coil diameter fits compact mechanical cavities
• 0.035-inch wire diameter provides consistent light-duty torsional force
• 1.071 in-lb torque at leg length for precise actuation control
• Steel construction for durability in mechanical assemblies

Compatibility

Designed as an OEM-style replacement torsion spring for mechanical assemblies requiring a left-hand wound, 180-degree deflection spring with a 0.281-inch rod size and 0.45-inch outside diameter.

Installation Notes

Torsion springs should be installed by qualified mechanical technicians familiar with spring-loaded assemblies. De-energize or disengage any actuated mechanism before removing or installing the spring to prevent unexpected release of stored energy. Use an appropriately sized arbor or mandrel no larger than the 0.281-inch maximum tool size to avoid coil distortion during installation. Do not over-deflect the spring beyond its rated angle, as permanent deformation may result.
