Gardner Spring MB0500-022 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0500-022 is a Belleville disc spring designed to deliver high load capacity in a compact axial footprint. With a 0.5 inch outer diameter, a 0.255 inch inner diameter, and an overall assembled height of 0.036 inches, this conical washer-style spring stores and releases energy under controlled axial compression. Rated at 1,167 pounds load at full deflection of 0.031 inches, it provides a high spring rate relative to its small form factor. The steel construction suits it for industrial fastening and precision mechanical assemblies where consistent clamp force or vibration resistance is required.

This disc spring is used in applications where a standard flat washer cannot maintain adequate clamping load over time, including bolted joint assemblies, valve stacks, bearing preload arrangements, and precision hardware subject to vibration or thermal cycling. The 1/4 inch bolt size compatibility makes it a practical choice for light-duty mechanical assemblies across manufacturing, equipment maintenance, and trade service applications. It is typically specified by mechanical assemblers, maintenance technicians, and equipment service professionals.

Key Features

• High load capacity of 1,167 pounds at 0.031 inches deflection in a compact 0.5 inch OD profile
• Steel construction for durability in mechanical fastening environments
• Compatible with 1/4 inch bolt size fastening arrangements
• 0.036 inch overall assembled height for space-constrained stack configurations
• Can be stacked in series or parallel to tune load and deflection characteristics

Compatibility

Designed for use with 1/4 inch bolt size fastener assemblies. Suitable as an OEM-style replacement or service component in bolted joint, bearing preload, and valve stack applications requiring a compact Belleville disc spring.

Installation Notes

Belleville disc springs are installed by mechanical assemblers and maintenance technicians using standard hand tools and torque equipment. Before servicing any assembly containing disc springs, de-energize or depressurize the equipment per the manufacturer service procedure. When stacking multiple springs, orientation relative to load direction determines whether springs act in series or parallel. Do not exceed the rated deflection, as flattening the spring beyond design limits can cause permanent set or failure.
