Gardner Spring GT5123409-MR Torsion Spring 90 Deg

Product Description

The GARDNER SPRING GT5123409-MR is a steel torsion spring designed for precise rotational force applications across mechanical assemblies, HVAC linkages, and light industrial equipment. It features a 0.408 inch outside diameter, a 0.051 inch wire diameter, and a right-hand direction of wind. With 4.25 coils and a 90 degree deflection angle, this spring delivers 3.107 inch-pounds of torque at the specified leg length. The maximum tool size for installation is 0.234 inches, matching the rod size for accurate fitment. Licensed technicians and mechanical assemblers working with small-format spring mechanisms will find this part dimensionally precise and ready for direct installation.

This torsion spring is suited for residential and commercial mechanical applications where controlled angular deflection is required. Typical uses include HVAC damper linkages, actuator return mechanisms, small appliance assemblies, and general-purpose industrial equipment requiring a compact right-hand wound torsion element. The 90 degree deflection angle makes it appropriate for quarter-turn actuation scenarios. The 2.000 inch leg length provides adequate leverage for consistent torque delivery across standard mounting configurations.

Key Features

• 90 degree deflection angle for quarter-turn actuation applications
• 0.408 inch coil outside diameter with 0.051 inch wire diameter for compact fitment
• Right-hand direction of wind for standard torsion spring orientations
• 3.107 inch-pounds torque at 2.000 inch leg length
• Maximum tool size and rod size of 0.234 inches for precise mandrel compatibility
• Steel construction for durability in mechanical service environments

Compatibility

Designed as an OEM-style replacement or direct-fit torsion spring for mechanical assemblies requiring a right-hand wound spring with 0.408 inch outside diameter, 0.051 inch wire diameter, and a 90 degree deflection angle.

Installation Notes

Installation should be performed by a qualified technician familiar with small spring mechanisms. De-energize or power down any connected mechanical or electrical assembly before removing or installing torsion springs. Use a mandrel or tool sized at or below 0.234 inches to avoid coil distortion during seating. Do not over-deflect beyond the rated 90 degree deflection angle, as permanent set or fatigue failure may result.
