Gardner Spring MB0875-045 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0875-045 is a Belleville disc spring - also known as a conical washer spring - designed to deliver high load capacity in a compact axial space. This spring measures 0.875 inches outer diameter and 0.442 inches inner diameter, with an overall assembled height (OAH) of 0.067 inches. Constructed from steel, it provides a rated load of 2,859.4 pounds at a deflection of 0.019 inches. Belleville disc springs are installed by mechanical contractors, industrial maintenance technicians, and assembly professionals who need precise, repeatable spring force in bolted joint or preload applications.

This disc spring is suited for applications requiring high load in a small footprint, such as bolted flange assemblies, valve components, bearing preload setups, and mechanical fastener stacks. The 7/16 inch bolt size compatibility makes it a direct fit for standard 7/16 inch fastener assemblies. It is commonly used in industrial, commercial, and trade service environments where consistent clamp load or vibration resistance is required in a fastened connection.

Key Features

• High load rating of 2,859.4 pounds at 0.019 inches deflection in a sub-1-inch diameter profile
• 0.875 inches outer diameter and 0.442 inches inner diameter for precise fitment on 7/16 inch bolt assemblies
• Overall assembled height of 0.067 inches allows use in tight axial clearance applications
• Steel construction provides durability under repeated loading cycles
• Sold individually with a package quantity of 12 - suitable for stacking or bulk replacement applications

Compatibility

Designed for use with 7/16 inch bolt size fastener assemblies. Consult stack configuration guidelines when using multiple Belleville disc springs in series or parallel arrangements to confirm combined load and deflection values.

Installation Notes

Belleville disc springs are installed by mechanical technicians and assembly professionals. Ensure the mating bolt, shaft, or bore dimensions match the spring ID and OD before installation. When stacking multiple disc springs, orientation - parallel versus series - directly affects load and deflection behavior; refer to applicable engineering data before assembly. Depressurize or de-energize any system before servicing spring-loaded components.
