Gardner Spring MB0500-022-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0500-022-S is a Belleville disc spring designed to deliver high load capacity within a compact axial footprint. This conical washer-style spring stores and releases energy under compressive load, making it well suited for bolt preload, vibration dampening, and precision clamping applications. Manufactured from stainless steel, it measures 0.5 inches in outer diameter with an inner diameter of 0.255 inches and an overall assembled height of 0.036 inches. At rated deflection of 0.019 inches, the spring delivers a load of 220.76 pounds. Mechanical assemblers, maintenance technicians, and industrial equipment specialists are the primary installers of this component.

This disc spring is used in applications requiring controlled axial force in tight spaces, including fastener preloading on 1/4-inch bolt sizes, valve assemblies, electrical connectors, and precision instrument housings. Its stainless steel construction makes it suitable for environments with moisture exposure or mild corrosive conditions. It is sold in packages of 12 and is appropriate for both light industrial and commercial mechanical assemblies where consistent spring force and dimensional repeatability are required.

Key Features

• Stainless steel construction resists corrosion and maintains spring properties in wet or humid environments
• 220.76-pound load capacity at 0.019 inches of deflection in a sub-inch form factor
• 0.5-inch outer diameter and 0.255-inch inner diameter sized for 1/4-inch bolt applications
• 0.036-inch overall height allows stacking in series or parallel for tuned load and deflection characteristics
• Packaged in quantities of 12, supporting both single-install and multi-unit service tasks

Compatibility

Designed as an OEM-style Belleville disc spring replacement for mechanical assemblies using 1/4-inch fasteners that require controlled axial preload.

Installation Notes

Belleville disc springs are installed by mechanical technicians using standard hand tools and calibrated torque equipment. Always depressurize or de-energize the assembly before servicing components under spring load. Stack orientation - series versus parallel - directly affects load and deflection results; refer to the equipment service manual for the correct stacking configuration. Do not exceed the rated deflection, as flattening the spring beyond its design limit can cause permanent deformation or fatigue failure.
