Gardner Spring MB2250-073 Belleville Disc Spring

Product Description

The GARDNER SPRING MB2250-073 is a Belleville disc spring designed to deliver precise axial load in a compact, stackable format. With a 2.25-inch outer diameter, a 1.125-inch inner diameter, and an overall assembled height of 0.148 inches, this spring applies a rated load of 32.1 pounds at its design deflection of 0.0193 inches. Constructed from steel, it is suited for applications requiring consistent spring force in tight axial spaces. Industrial maintenance technicians, mechanical assemblers, and OEM equipment builders typically install this type of component.

Belleville disc springs are used where a high load must be delivered over a short stroke. Common applications include bolt preload retention, valve assemblies, clutch packs, bearing preload, and vibration damping in mechanical systems. This spring is sized for use with a 1-1/8-inch bolt, making it a direct-fit choice in flanged joints or fastened assemblies where controlled clamping force is required. It is suitable for both light industrial and precision mechanical applications.

Key Features

• 2.25-inch outer diameter for consistent radial seating in standard bores
• 1.125-inch inner diameter sized for 1-1/8-inch bolt installations
• 0.148-inch overall height allows stacking in series or parallel configurations
• 32.1-pound load rating at 0.0193-inch deflection for predictable spring performance
• Steel construction provides durability under compressive cycling

Compatibility

Designed for use with 1-1/8-inch bolt sizes in mechanical assemblies requiring a 2.25-inch OD Belleville disc spring. Confirm bore diameter, bolt size, and stack height requirements before installation.

Installation Notes

Belleville disc springs are installed by mechanical assemblers or maintenance technicians familiar with fastened joint design. Relieve any system load or pressure before servicing the assembly. Springs may be stacked in series to increase deflection range or in parallel to increase load capacity - verify stack orientation matches design intent. Do not exceed the rated deflection, as overcompression can cause permanent set or component damage.
