Gardner Spring MB2000-065-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB2000-065-S is a Belleville disc spring designed to deliver controlled axial load in a compact, stackable format. This conical washer-style spring measures 2 inches in outer diameter and 1 inch in inner diameter, with an overall assembled height of 0.13 inches. Manufactured from stainless steel, it provides 0.088 inches of deflection and a rated load of 44.7 pounds at full deflection. Belleville disc springs of this type are installed by mechanical technicians, maintenance engineers, and trade professionals working in high-load, low-deflection fastening and clamping applications.

This spring is suited for applications where consistent preload is required in a confined axial space. Typical uses include bolt and fastener assemblies, valve components, flanged connections, and industrial clamping systems. Its stainless steel construction makes it appropriate for environments with moisture exposure, mild corrosion risk, or sanitary requirements. The 1-inch bolt size attribute indicates fitment around standard 1-inch fasteners in mechanical and process equipment assemblies.

Key Features

• 2 inches outer diameter and 1 inch inner diameter for precise fitment on 1-inch bolt assemblies
• Stainless steel construction for corrosion resistance in demanding environments
• 0.088 inches deflection range with a rated load of 44.7 pounds at full deflection
• Low-profile design at 0.13 inches overall height allows use in tight axial spaces
• Stackable geometry supports series or parallel arrangements to tune load and deflection

Compatibility

Designed for use with 1-inch bolt size assemblies as an OEM-style or aftermarket Belleville disc spring in mechanical, industrial, and process equipment applications.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians. Disengage all load and de-energize any connected equipment before replacing or installing disc springs. Use appropriate torque tools when seating into fastener assemblies and ensure the spring is oriented correctly, as reversing or alternating stacking orientation changes the load-deflection curve. Consult the equipment manufacturer's assembly drawings for correct stack configuration and preload requirements.
