Gardner Spring MB3000-093 Belleville Disc Spring

Product Description

The GARDNER SPRING MB3000-093 is a Belleville disc spring designed to deliver high load capacity in a compact axial footprint. This conical washer-style spring stores and releases energy under compression, making it well suited for applications requiring precise, repeatable clamping or preload force. The MB3000-093 features a 3-inch outer diameter, a 1.5-inch inner diameter, and an overall assembled height of 0.189 inches. It is manufactured from steel and delivers a rated load of 41.59 pounds at a deflection of 0.0472 inches. Mechanical engineers, millwrights, and industrial maintenance technicians are the primary installers of this component in bolted joint and preload assemblies.

This Belleville disc spring is used in applications where axial space is limited but sustained clamping or preload force is required. Typical installations include flanged pipe joints, valve assemblies, rotating equipment, and bolted mechanical connections requiring bolt-load retention. The 1.5-inch bolt size compatibility makes it a standard fit for heavy-duty mechanical fastening systems in industrial, commercial, and OEM equipment environments. Springs of this type are frequently stacked in series or parallel to tune load and deflection characteristics to specific application requirements.

Key Features

• 3-inch outer diameter and 1.5-inch inner diameter for use with 1.5-inch bolt sizes
• Rated load of 41.59 pounds at 0.0472 inches of deflection for predictable preload performance
• Low-profile design at 0.189 inches overall height conserves axial space in tight assemblies
• Steel construction provides durability under repeated compression cycling
• Can be stacked in series or parallel to adjust load and deflection range

Compatibility

Designed for use with 1.5-inch bolt size fastening applications. Suitable for flanged joints, valve assemblies, and mechanical preload systems requiring a 3-inch OD Belleville-style disc spring.

Installation Notes

Installation is typically performed by millwrights, mechanical technicians, or maintenance engineers during assembly or maintenance of bolted mechanical joints. Depressurize or de-energize the assembly before disassembly and spring replacement. Ensure mating surfaces are clean and free of burrs that could affect seating or load distribution. When stacking multiple disc springs, verify the stacking orientation against the application load-deflection requirement before torquing fasteners.
