Gardner Spring MU500-0211 Curved Disc Spring

Product Description

The GARDNER SPRING MU500-0211 is a curved disc spring designed for applications requiring controlled load and deflection in a compact axial space. This spring measures 1.225 inches in outer diameter, 0.525 inches in inner diameter, and 0.151 inches in overall height. It is constructed from steel and delivers a load of 124.1 pounds at its rated deflection of 0.0413 inches. Curved disc springs of this type are used by mechanical and industrial trade professionals in assemblies where precise spring force must be maintained within tight dimensional constraints.

This spring is suited for use with 1/2 inch bolt sizes, making it a practical choice for bolted flange assemblies, valve stacks, and mechanical preload applications. Its curved profile distributes load evenly across the disc contact surface, which helps maintain consistent clamping force over time. Licensed mechanics and industrial maintenance technicians typically install these springs in equipment where vibration or thermal cycling can cause fastener loosening or loss of preload.

Key Features

• Steel construction for durability under repeated load cycles
• 124.1 pound load capacity at rated deflection
• 0.0413 inch deflection rating for precise spring-rate control
• 1.225 inch OD fits standard 1/2 inch bolt size assemblies
• Compact 0.151 inch overall height for use in tight axial spaces

Compatibility

Designed for use with 1/2 inch bolt size fastener assemblies. Verify inner diameter, outer diameter, and load requirements against your application specifications before installation.

Installation Notes

Install curved disc springs with proper orientation as specified by the equipment manufacturer, as stacking direction affects load and deflection characteristics. Ensure mating surfaces are clean and free of burrs before assembly. Consult applicable mechanical codes and equipment service documentation when replacing springs in pressurized or safety-critical assemblies. Always de-energize and relieve system pressure before disassembling spring-loaded components.
