Gardner Spring 1112270135SR Torsion Spring 270 Deg

Product Description

The GARDNER SPRING 1112270135SR is a torsion spring engineered for applications requiring precise rotational force and controlled angular deflection. Built with a 0.135-inch wire diameter and a 1.666-inch outside diameter, this spring delivers 40 inch-pounds of torque at leg length across a 270-degree deflection angle. The coil body consists of 9.75 coils, providing consistent spring rate and reliable return force. It is sized for tooling with a maximum tool size of 1.112 inches. HVAC technicians, equipment assemblers, and mechanical maintenance professionals install this spring in actuators, damper mechanisms, valve assemblies, and similar rotating-force applications.

This torsion spring suits residential and light commercial mechanical assemblies where a controlled angular return force is required. Typical applications include damper actuators, door mechanisms, equipment linkage assemblies, and spring-loaded valve components found in HVAC, plumbing, and general mechanical systems. The 270-degree deflection angle makes it appropriate for applications requiring a near-full rotational range of motion under load. The 4.000-inch leg length supports standard mounting configurations common in these assemblies.

Key Features

• 270-degree deflection angle for wide-range rotational applications
• 1.666-inch coil outside diameter with 0.135-inch wire diameter for structural rigidity
• 9.75 coils provide consistent spring rate and smooth deflection
• 40 inch-pounds torque at leg length for reliable return force
• Maximum tool size of 1.112 inches for straightforward installation with standard tooling
• 4.000-inch leg length supports common mounting configurations

Compatibility

Designed as an OEM-style replacement torsion spring for mechanical assemblies requiring a 270-degree deflection angle, 1.666-inch outside diameter, and 0.135-inch wire diameter specification.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with spring-loaded assemblies. Relieve all stored mechanical energy and de-energize the system before removing or installing torsion springs. Use tooling no larger than 1.112 inches in diameter to avoid coil distortion. Do not exceed the rated deflection angle during installation, as over-winding can cause permanent set or failure.
