Gardner Spring GT7840609-MR Torsion Spring 90 Degree

Product Description

The GARDNER SPRING GT7840609-MR is a right-hand wound steel torsion spring designed for mechanical assemblies requiring precise rotational force and controlled angular deflection. With a 90-degree deflection angle and a torque rating of 10.446 inch-pounds at leg length, this spring delivers consistent, repeatable performance in demanding applications. The outside diameter measures 0.678 inches, wire diameter is 0.078 inches, and the leg length is 2.000 inches. The spring features 4.25 coils and is compatible with rod sizes up to 0.406 inches. Mechanical assembly technicians, OEM production teams, and maintenance professionals will find this spring suited for precision spring-loaded mechanisms.

This torsion spring is used in mechanical assemblies where a controlled rotational return force is needed. Typical applications include latching mechanisms, hinges, spring-loaded levers, and actuator returns found in industrial equipment, HVAC components, and general mechanical devices. The right-hand wind direction should be confirmed against the assembly design before installation. The maximum tool size for installation is 0.406 inches, which aligns with the rod size specification. This spring is sold in a package quantity of 6 units with a minimum order quantity of 1.

Key Features

• 90-degree deflection angle for precise rotational force applications

• 10.446 inch-pounds torque at leg length for consistent return force
• 0.678 inch outside diameter with 0.078 inch wire diameter for compact fitment
• Steel construction for durability in mechanical and industrial environments
• Compatible with rod sizes up to 0.406 inches and maximum tool size of 0.406 inches

Compatibility

Designed as an OEM-style replacement or direct-use torsion spring for mechanical assemblies requiring a right-hand wound spring with a 0.678 inch outside diameter, 0.078 inch wire diameter, and 90-degree deflection angle.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with spring-loaded assemblies. Relieve all tension and de-energize the assembly before removing or installing torsion springs to prevent injury from stored energy. Confirm the wind direction matches the assembly requirement before seating the spring on the rod. Use appropriately sized tooling at or below the 0.406 inch maximum tool size to avoid deforming the coils during installation.
