Gardner Spring MB0625-022 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0625-022 is a Belleville disc spring engineered for applications requiring controlled axial load within a compact envelope. With an outer diameter of 0.625 inches, an inner diameter of 0.317 inches, and an overall assembled height of 0.042 inches, this spring delivers a rated load of 22.03 pounds at its specified deflection of 0.021 inches. Constructed from steel, the MB0625-022 provides consistent spring force in stacked or single configurations. It is suited for use in mechanical assemblies, fastener preload systems, and precision load applications where space is limited and repeatable force is required.

This Belleville disc spring is used in a wide range of industrial and mechanical applications including valve assemblies, pipe flanges, bolted joint preload, and vibration isolation mounts. Its compact 0.625-inch outer diameter makes it a practical choice for 5/16-inch bolt applications where maintaining clamp load under thermal cycling or dynamic loading is critical. Trade professionals in HVAC, plumbing, and industrial maintenance will encounter this spring in equipment requiring precise axial force management across multiple stacked configurations.

Key Features

• 0.625 inches outer diameter and 0.317 inches inner diameter for 5/16-inch bolt compatibility
• 22.03-pound load rating at 0.021-inch deflection for predictable spring force
• 0.042-inch overall assembled height allows compact stacking in tight assemblies
• Steel construction provides durability under repeated compression cycles
• Sold in packages of 12 to support multi-spring stacked arrangements

Compatibility

Designed as a standard Belleville disc spring for 5/16-inch bolt applications in mechanical, industrial, and trade equipment assemblies requiring axial preload or load control.

Installation Notes

Installation is typically performed by a licensed mechanic or qualified trades professional during equipment assembly or maintenance. Always de-energize or depressurize the host system before disassembling fastened joints. When stacking Belleville disc springs, orient them per the assembly drawing to achieve the intended load and deflection characteristics. Follow applicable mechanical codes and the equipment manufacturer guidelines for torque and preload requirements.
