Gardner Spring MU500-0113-S Curved Disc Spring

Product Description

The GARDNER SPRING MU500-0113-S is a curved disc spring manufactured from stainless steel, designed to deliver consistent load and deflection performance in fastening and clamping assemblies. With an outer diameter of 0.795 inches, an inner diameter of 0.531 inches, and an overall assembled height of 0.129 inches, this spring fits 1/2-inch bolt applications. It delivers a rated load of 54.6 pounds at a deflection of 0.0384 inches. Curved disc springs are used by mechanical assemblers, maintenance technicians, and industrial service professionals where controlled spring force is required in a compact axial footprint.

This curved disc spring is suited for residential and commercial mechanical assemblies, fastener preload applications, and vibration-dampening installations. Its stainless steel construction makes it appropriate for environments where corrosion resistance is a priority. The 1/2-inch bolt size compatibility allows straightforward integration into standard fastener stacks without modification. It ships in packages of 10, making it practical for service kits and maintenance inventories that require multiple units per job.

Compatibility

Designed for use with 1/2-inch bolt size fastener assemblies as an OEM-style curved disc spring in mechanical clamping, preload, and vibration-dampening applications.

Installation Notes

Installation is typically performed by mechanical technicians or industrial maintenance professionals familiar with spring stack assemblies. De-energize and depressurize any equipment before disassembling fastener joints that incorporate disc springs. Ensure correct orientation of the curved profile per the assembly drawing, as reversing or stacking orientation affects load and deflection characteristics. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes when reassembling fastened joints.
