Gardner Spring MB2000-065 Belleville Disc Spring

Product Description

The GARDNER SPRING MB2000-065 is a Belleville disc spring designed to deliver controlled load in a compact axial footprint. This conical washer-style spring generates a rated load of 11.47 pounds at its full deflection of 0.0945 inches, making it suitable for applications where precise preload or vibration damping is required in tight spaces. Constructed from steel, it measures 2 inches outer diameter and 1 inch inner diameter, with an overall assembled height of 0.13 inches. HVAC equipment assemblers, industrial maintenance technicians, and mechanical contractors use Belleville disc springs to maintain consistent clamping force on fastened joints subject to thermal cycling or dynamic loading.

Belleville disc springs are commonly used in bolted flange assemblies, valve actuators, pump housings, and mechanical equipment where a standard coil spring cannot fit within the available stack height. The MB2000-065 is suited for use with 1-inch bolt sizes, allowing it to be stacked in series or parallel to tune load and deflection characteristics to a specific application requirement. It is appropriate for both residential and light commercial mechanical systems as well as general industrial equipment.

Key Features

• Steel construction for durability under cyclic compressive loading
• 2 inches outer diameter and 1 inch inner diameter for use with 1-inch bolt sizes
• 11.47 pounds load capacity at rated deflection of 0.0945 inches
• 0.13 inches overall assembled height enables use in space-constrained assemblies
• Can be stacked in series or parallel to adjust load and deflection as needed

Compatibility

Designed as a standard Belleville disc spring replacement for assemblies requiring a 1-inch bore, 2-inch outer diameter conical washer spring in steel construction.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with spring stack configurations. De-energize and depressurize the assembly before disassembly or spring replacement. When stacking multiple disc springs, confirm series versus parallel orientation against the original equipment specification to achieve the intended load curve. Do not exceed the rated deflection, as over-compression can permanently deform the spring and reduce load capacity.
