Gardner Spring GT1507818-MR Torsion Spring 180 Degree

Product Description

The GARDNER SPRING GT1507818-MR is a miniature right-hand wound torsion spring engineered for precision applications requiring controlled rotational force. Built from steel with a 0.013 inch wire diameter and a 0.13 inch outside coil diameter, this spring delivers 0.1 inch-pound of torque at leg length across a 180-degree deflection angle. With 5 active coils and a 0.5 inch leg length, it is sized for tight-tolerance assemblies in instruments, small appliances, medical devices, and mechanical sub-components. Installation is handled by mechanical assemblers, machine builders, and technicians working at the component level.

This torsion spring suits residential and commercial applications where compact rotational return force is needed. It is commonly installed in small mechanical assemblies, hinged panels, latching mechanisms, and light-duty actuating systems. The 0.078 inch maximum tool size and rod size designation indicate compatibility with narrow-bore mandrel tooling. It ships in packages of 6 units with a minimum order quantity of 1.

Key Features

• 180-degree deflection angle provides a full half-rotation of stored torsional energy
• Right-hand direction of wind for standard rotational return applications
• 0.13 inch outside coil diameter fits tight-clearance mechanical assemblies
• 0.015 inch wire diameter yields a low-profile, lightweight spring body
• 0.1 inch-pound torque at leg length for light-duty precision actuation
• Steel construction for durability in mechanical environments

Compatibility

Designed as an OEM-style replacement torsion spring for small mechanical assemblies requiring a right-hand wound spring with a 0.13 inch outside diameter, 0.015 inch wire diameter, 180-degree deflection, and a 0.078 inch maximum rod or tool size.

Installation Notes

Installation is performed by mechanical assemblers or technicians working on component-level sub-assemblies. Ensure all equipment is de-energized or de-pressurized before replacing any spring component. Use a mandrel or tooling pin no larger than 0.078 inches to seat the spring without overdeforming the coils. Avoid exceeding the rated deflection angle, as over-travel beyond 180 degrees may permanently deform the spring body.
