Gardner Spring 500090105MR Torsion Spring 90 Deg

Product Description

The GARDNER SPRING 500090105MR is a right-hand wound torsion spring designed for mechanical assemblies requiring precise angular deflection. Built from steel, this spring delivers 90 degrees of deflection with an outside coil diameter of 0.848 inches and a wire diameter of 0.106 inches. With 3.25 active coils and a leg length of 3.5 inches, it provides consistent torque output at 22.47 inch-pounds measured at leg length. A maximum tool size of 0.5 inches accommodates standard installation tooling. Designed for engineers and maintenance technicians working with spring-loaded mechanisms in HVAC equipment, industrial assemblies, and related trade applications.

This torsion spring suits applications where a compact, right-hand wound steel spring is required to return a mechanism to a set position after angular displacement. With a rod size of 0.5 inches, it fits standard pivot rods and shafts common in damper actuators, door mechanisms, and similar rotating assemblies. The 90-degree deflection angle makes it appropriate for quarter-turn return applications found in residential and light commercial mechanical systems.

Key Features

• 90-degree deflection angle for quarter-turn return applications
• Right-hand wind direction for standard spring-loaded mechanisms
• 0.848 inches outside coil diameter with 3.25 active coils
• 0.106 inches wire diameter for consistent torque delivery
• 22.47 inch-pounds torque at leg length
• Steel construction for durability in mechanical assemblies

Compatibility

Designed as a replacement or OEM-style torsion spring for mechanical assemblies requiring a right-hand wound spring with a 0.5 inch maximum tool size and 0.5 inch rod size compatibility.

Installation Notes

Installation should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. Relieve all tension from the mechanism and de-energize any associated equipment before removing or installing torsion springs. Use a tool no larger than 0.5 inches when winding or unwinding the spring to avoid coil distortion. Refer to the equipment manufacturer's service documentation for specific assembly sequence and torque verification procedures.
