Gardner Spring MU750-0210-S Curved Disc Spring

Product Description

The GARDNER SPRING MU750-0210-S is a curved disc spring manufactured from stainless steel, designed to deliver controlled load and deflection in compact fastener and clamping assemblies. With an outer diameter of 1.103 inches, an inner diameter of 0.8 inches, and an overall assembled height of 0.138 inches, this spring provides a rated load of 8,337.5 pounds at a deflection of 0.0388 inches. The curved disc profile stores and releases energy efficiently under axial compressive loads, making it a reliable component in high-load, limited-travel applications. Licensed technicians and mechanical tradespeople install these springs in bolted joint assemblies, valve mechanisms, and precision equipment requiring consistent spring force.

This curved disc spring is suited for applications where a 3/4-inch bolt size is specified. Its stainless steel construction resists corrosion, making it appropriate for use in environments exposed to moisture, chemicals, or elevated temperatures. The compact geometry allows stacking in series or parallel arrangements to tune load and deflection characteristics as needed by the application. Typical install scenarios include industrial machinery, HVAC equipment fastener joints, plumbing valve assemblies, and structural bolted connections requiring controlled preload.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• Curved disc profile delivers consistent axial load at precise deflection values
• Rated load of 8,337.5 pounds at 0.0388 inches deflection
• Compatible with 3/4-inch bolt size fastener assemblies
• Compact dimensions allow stacking for custom load-deflection tuning

Compatibility

Designed for use in 3/4-inch bolt size fastener assemblies requiring a curved disc spring with a 1.103-inch outer diameter and 0.8-inch inner diameter.

Installation Notes

Installation should be performed by a qualified mechanical tradesperson familiar with spring fastener assemblies and applicable mechanical codes. Always relieve system pressure and de-energize equipment before disassembling bolted joints. When stacking disc springs, confirm the orientation and stacking pattern against the load-deflection requirements of the application. Avoid exceeding the rated deflection, as over-compression can permanently deform the spring.
