Gardner Spring MC103-0780-M Precision Compression Spring

Product Description

The GARDNER SPRING MC103-0780-M is a precision compression spring manufactured from stainless steel with a plain finish. It features a 0.555-inch outside diameter and a free length of 3.071 inches, making it a compact, high-load spring suited for demanding mechanical assemblies. With a maximum work load of 135.33 pounds and a spring rate of 13.64 pound-force per inch, this spring delivers consistent, repeatable force output across its compression range. Closed and ground ends provide stable seating and precise load transfer. It is appropriate for applications where dimensional accuracy and material quality are critical to performance.

This precision compression spring is used in mechanical, industrial, and OEM assembly applications where controlled compression force is required. Its stainless steel construction makes it suitable for environments with exposure to moisture or mild corrosives. Typical installations include valve assemblies, actuators, fluid control components, and precision machinery. Machinists, millwrights, and OEM assembly technicians are the primary installers. The spring ships in a package quantity of five units per order.

Key Features

• Closed and ground end type for stable, flat seating and accurate load application
• Maximum work load of 135.33 pounds for high-force compression applications
• Spring rate of 13.64 pounds per inch for predictable, linear deflection
• Stainless steel construction with plain finish for corrosion resistance
• Manufactured to DIN 17223, DIN 17224, and DIN 2095 standards for dimensional and material precision
• Solid height of 0.913 inches, limiting compression travel for controlled stroke applications

Compatibility

Designed as an OEM-style precision compression spring suitable for mechanical assemblies requiring a 0.555-inch outside diameter closed and ground spring conforming to DIN compression spring standards.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers during equipment build or maintenance. Before servicing any assembly containing this spring, relieve all mechanical load and de-energize any associated pneumatic or hydraulic systems. Verify the spring seat diameter and pocket depth against the 0.555-inch OD and 0.913-inch solid height before installation. Do not compress the spring beyond its solid height during assembly or testing.
