Gardner Spring 666090135MR Torsion Spring 90 Deg 1.102in Od

Product Description

The GARDNER SPRING 666090135MR is a right-hand wound steel torsion spring engineered for applications requiring a 90-degree deflection angle. With a coil outside diameter of 1.102 inches and a wire diameter of 0.135 inches, this spring delivers 42.86 inch-pounds of torque at leg length. It features 4.25 coils and a 4.000-inch leg length, making it a compact, precision-wound component suited for mechanical assemblies where controlled rotational force and consistent return motion are required. Installation is performed by mechanical technicians and maintenance professionals working on equipment drives, hinges, latches, and similar torsion-loaded mechanisms.

This torsion spring is intended for use in industrial and commercial mechanical assemblies where a right-hand wound spring with a 90-degree deflection angle is specified. Typical applications include equipment linkages, door mechanisms, and machine component assemblies that require a defined torque output. The 0.666-inch maximum tool size and rod size guide proper tooling selection during installation. Its steel construction supports use in standard indoor mechanical environments.

Key Features

• 90-degree deflection angle for precise rotational force application
• Right-hand direction of wind for standard torsion loading
• 1.102-inch coil outside diameter with 0.135-inch wire diameter
• 42.86 inch-pounds torque output at leg length
• 4.25 coils with 4.000-inch leg length for compact fitment
• Steel construction for durability in mechanical assemblies

Compatibility

Designed as a precision torsion spring replacement or new-installation component for mechanical assemblies specifying a right-hand wound spring with a 1.102-inch outside diameter, 0.135-inch wire diameter, 90-degree deflection, and a 0.666-inch maximum tool size.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with torsion spring handling. De-energize or lock out any equipment before removing or installing spring components to prevent unexpected release of stored energy. Use tooling sized at or below the 0.666-inch maximum tool size to avoid coil distortion. Do not wind or unwind the spring beyond its rated deflection angle, as over-deflection can permanently deform the coil body.
