Gardner Spring MB1375-044-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB1375-044-S is a Belleville disc spring manufactured from stainless steel for reliable performance in high-load, limited-deflection applications. With a 1.375-inch outer diameter, a 0.692-inch inner diameter, and an overall assembled height of 0.088 inches, this conical washer-style spring delivers a rated load of 2333.5 pounds at its full deflection of 0.1181 inches. Belleville disc springs are used where precise axial load control is required in a compact stack configuration. Licensed tradespeople and mechanical contractors working in HVAC equipment, pump assemblies, valve actuators, and industrial fastening applications rely on components like this to maintain consistent clamping force over service life.

This spring is suited for use in applications requiring a bolt or fastener with an 11/16-inch bolt size. Its stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, including wet mechanical rooms, pool equipment enclosures, and outdoor HVAC installations. The high load-to-height ratio makes it a practical choice when axial spring force must be achieved in a very shallow stack depth. It is sold in a package quantity of six with a minimum order quantity of one package.

Compatibility

Designed for use with 11/16-inch bolt sizes. Suited as an OEM-style or aftermarket Belleville disc spring in mechanical, HVAC, plumbing, and industrial assemblies requiring this outer diameter and load specification.

Installation Notes

Belleville disc springs are typically installed by licensed mechanical contractors or industrial maintenance technicians. Ensure the mating surfaces are clean and free of burrs before seating the spring to avoid uneven load distribution. Stack orientation and series versus parallel arrangement will affect the resulting load and deflection characteristics - consult the original equipment documentation for the correct configuration. De-energize or depressurize any associated system before disassembling fastened joints where these springs are used.
