Gardner Spring MB0625-032-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0625-032-S is a Belleville disc spring engineered for high-load applications in compact spaces. This conical washer-style spring generates significant clamping or preload force with minimal axial travel. With an outer diameter of 0.625 inches, an inner diameter of 0.317 inches, and an overall assembled height of 0.048 inches, it is built for installations where space is tight and consistent load retention is critical. Constructed from stainless steel, this disc spring resists corrosion and maintains performance in harsh or wet environments. It delivers a rated load of 845.8 pounds at its working deflection of 0.015 inches.

Belleville disc springs in this size range are commonly used in bolted flange assemblies, valve seats, electrical connectors, pump housings, and precision mechanical fastening systems. The 5/16-inch bolt size compatibility makes this spring a direct fit for standard 5/16-inch fastener stacks in both light industrial and mechanical service applications. Installers in HVAC, plumbing, and industrial maintenance will encounter this spring where controlled preload or vibration dampening is required at a bolted joint.

Key Features

• Stainless steel construction for corrosion resistance in wet or chemically active environments
• 845.8 pound load capacity at 0.015 inches of deflection for precise preload control
• 0.625 inches outer diameter with 0.317 inches inner diameter sized for 5/16-inch bolt applications
• 0.048 inches overall height enables use in minimal axial-space assemblies
• Conical disc geometry provides high spring rate in a low-profile form factor

Compatibility

Designed for use with 5/16-inch bolt fastener assemblies. Suitable as an OEM-style replacement or new-build component in bolted joint, flange, and valve applications requiring a 0.625-inch OD Belleville disc spring.

Installation Notes

Belleville disc springs are installed by mechanical technicians familiar with bolted joint preload requirements. Ensure the mating surfaces are clean and free of burrs before seating the spring. Springs may be stacked in series to increase deflection range or in parallel to increase load capacity - confirm the correct stacking orientation before assembly. Follow applicable fastener torque specifications for the host assembly as defined by the equipment manufacturer or relevant industry standards.
