Gardner Spring MB0625-047-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0625-047-S is a Belleville disc spring engineered for high-load applications in compact assemblies. Manufactured from stainless steel, this conical washer-style spring delivers a rated load of 4,907 pounds at deflection, with a working deflection range of 0.06 to 0.09 inches. The overall height (OAH) measures 0.059 inches, the outer diameter is 0.625 inches, and the inner diameter is 0.317 inches. These springs are installed by maintenance technicians, mechanical assemblers, and industrial service professionals working with bolted joints, valve assemblies, and precision load-bearing connections.

This disc spring is suited for use in applications requiring consistent, high-force clamping or preload in a minimal axial footprint. The 5/16-inch bolt size compatibility makes it appropriate for standard fastener assemblies in industrial, HVAC mechanical, and fluid-handling equipment. It is commonly stacked in series or parallel to adjust load and deflection characteristics to meet specific assembly requirements.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• 4,907-pound rated load at deflection for high-force, compact applications
• Deflection range of 0.06 to 0.09 inches allows controlled spring travel
• 0.625-inch outer diameter with 0.317-inch inner diameter fits 5/16-inch bolt size
• Low-profile OAH of 0.059 inches suits tight axial clearance designs
• Stackable in series or parallel configurations for load and deflection tuning

Compatibility

Designed for use with 5/16-inch bolt assemblies. Suitable as an OEM-style replacement or new-installation Belleville disc spring in industrial bolted joint, valve, and mechanical preload applications where this OD and ID specification is required.

Installation Notes

Installation is typically performed by qualified mechanical or industrial service technicians. De-energize and relieve all system pressure before disassembling any joint or valve assembly. Ensure bolt, bore, and mating surface dimensions are confirmed against spring specifications before installation. When stacking multiple disc springs, follow the assembly drawing or OEM specification for series versus parallel orientation to achieve the intended load-deflection curve.
