Gardner Spring 666090135SR Torsion Spring 90 Deg Rh

Product Description

The GARDNER SPRING 666090135SR is a right-hand wound torsion spring engineered for mechanical assemblies that require precise rotational force at a defined deflection angle. Built from stainless steel, this spring delivers 40 inch-pounds of torque at leg length across a 90-degree deflection angle. The coil outside diameter measures 1.102 inches with a wire diameter of 0.135 inches and 4.25 active coils, making it suitable for close-tolerance applications. It is installed by maintenance mechanics, industrial technicians, and trade professionals who require consistent spring performance in demanding environments.

This torsion spring is suited for use in a range of mechanical and electromechanical assemblies where rotational return force is needed. Its stainless steel construction offers corrosion resistance, making it appropriate for HVAC equipment, plumbing valve mechanisms, electrical panel hardware, and light industrial machinery. The 0.666-inch maximum tool size and 4-inch leg length support straightforward installation in confined mounting locations. Typical applications include damper actuators, latching mechanisms, and rotating component returns in both residential and commercial equipment.

Key Features

• 90-degree deflection angle provides defined rotational stop for consistent return-force applications
• Stainless steel construction resists corrosion in wet, humid, or chemically exposed environments
• Right-hand wind direction for compatibility with standard clockwise-load assemblies
• 40 inch-pounds torque at leg length for predictable force output
• 1.102-inch coil outside diameter and 0.135-inch wire diameter for close-tolerance fitment
• Maximum tool size of 0.666 inches supports installation with standard tooling

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies requiring a right-hand wound torsion spring with a 1.102-inch outside diameter, 0.135-inch wire diameter, 90-degree deflection, and 4.25 coils.

Installation Notes

Torsion springs store rotational energy and must be handled with care during installation and removal. De-energize or fully relieve tension from the assembly before replacing the spring. Use appropriate tooling sized to the 0.666-inch maximum tool opening and avoid overextending the spring beyond its rated deflection angle. Verify wind direction matches the assembly requirement before installation to prevent improper loading.
