Gardner Spring MB0950-047 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0950-047 is a Belleville disc spring designed to deliver high load capacity in a compact axial space. With an outer diameter of 0.95 inches, an inner diameter of 0.38 inches, and an overall assembled height of 0.07 inches, this conical washer-style spring stores and releases energy under compressive load. At full deflection of 0.048 inches, the spring develops a load of 19,209.2 pounds. Manufactured from steel, it is suited for demanding fastening and clamping assemblies where conventional coil springs cannot meet space or load requirements. Maintenance technicians and mechanical assemblers working in industrial, HVAC, and equipment manufacturing applications are the primary installers.

This disc spring is sized for 3/8 inch bolt applications, making it a direct fit in bolted joint assemblies, valve stacks, bearing preload arrangements, and vibration-damping stacks. The high load-to-height ratio makes it appropriate for applications where axial space is constrained but clamping force requirements are substantial. It can be used individually or stacked in series or parallel configurations to tune load and deflection characteristics to a specific assembly requirement.

Key Features

• High load rating of 19,209.2 pounds at 0.048 inches of deflection for a compact spring element
• 0.95 inches outer diameter and 0.38 inches inner diameter sized for 3/8 inch bolt hardware
• Overall assembled height of 0.07 inches allows use in tight axial envelopes
• Steel construction provides durability under repeated compressive cycling
• Stackable design supports series or parallel arrangements to adjust load and travel

Compatibility

Designed for use in 3/8 inch bolt assemblies requiring a Belleville disc spring with 0.95 inches outer diameter and 0.38 inches inner diameter. Verify load, deflection, and material requirements against your specific assembly specification before installation.

Installation Notes

Installation is typically performed by mechanical assemblers or maintenance technicians using standard hand tools and torque wrenches. Before servicing any assembly containing disc springs, de-energize or depressurize the system as required by the equipment manufacturer. Observe correct stacking orientation as printed in the assembly drawing, since reversing spring direction affects load and deflection output. Follow applicable industry standards and equipment OEM specifications for final torque values.
