Gardner Spring MB2000-142 Belleville Disc Spring

Product Description

The GARDNER SPRING MB2000-142 is a Belleville disc spring designed for applications requiring high load capacity in a compact axial space. This conical washer-style spring measures 2 inches outer diameter, 1 inch inner diameter, and 0.177 inches overall height. Fabricated from steel, it delivers a rated load of 3,494 pounds at its specified deflection of 0.009 inches. Belleville disc springs of this type are installed by mechanical tradespeople, maintenance technicians, and industrial assembly specialists wherever precise preload, vibration dampening, or bolt tension retention is required.

This spring is suited for bolted joint assemblies, valve components, flanged connections, and mechanical preload applications where axial space is limited but high clamping force is needed. The 1 inch bolt size rating makes it a direct fit for standard 1 inch bolt and fastener configurations in industrial, HVAC equipment mounting, and mechanical system assemblies. Its steel construction provides durability under repeated compression cycles in both stationary and dynamic load environments.

Key Features

• 2 inches outer diameter and 1 inch inner diameter for 1 inch bolt size applications
• 0.177 inches overall height allows installation in tight axial clearances
• 3,494 pound load rating at 0.009 inches deflection delivers high force output in a small footprint
• Steel construction for durability under repeated compression and cyclic loading
• Conical disc profile provides consistent spring rate and reliable preload retention

Compatibility

Designed for use with 1 inch bolt size fastener assemblies. Suitable as an OEM-style replacement or new installation Belleville disc spring in bolted joint, valve, and mechanical preload applications requiring a 2 inch OD conical washer spring.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance tradespeople using standard hand tools. De-energize or depressurize the assembly before servicing any bolted joint or valve component. Belleville disc springs may be stacked in series or parallel to adjust deflection range or load capacity - verify the intended stack configuration against system design requirements before assembly. Follow applicable equipment manufacturer torque and preload specifications for the host fastener.
