Gardner Spring MB0750-036 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0750-036 is a Belleville disc spring designed to deliver high load capacity in a compact axial footprint. Also known as a conical washer spring, it generates significant clamping or cushioning force when deflected along its axis. This spring measures 0.75 inches outer diameter, 0.255 inches inner diameter, and 0.054 inches overall height. At its rated deflection of 0.032 inches, it produces a load of 32,659.6 pounds. It is suited for applications where space is limited but precise, repeatable spring force is required. Mechanical engineers, maintenance technicians, and industrial assembly professionals typically specify and install this component.

Belleville disc springs of this size are used in bolt preload assemblies, valve seats, clutch packs, pressure relief mechanisms, and vibration dampening stacks. This spring is sized for a 1/4 inch bolt, making it a direct fit for standard fastener assemblies in that bolt diameter range. It is appropriate for both light industrial and precision mechanical applications where controlled deflection and consistent load response are critical to performance and safety.

Key Features

• High load capacity of 32,659.6 pounds at 0.032 inches deflection
• Compact form factor: 0.75 inches OD, 0.255 inches ID, 0.054 inches overall height
• Sized for 1/4 inch bolt applications
• Steel construction for durability under compressive load cycling
• Sold individually with a package quantity of 12 per pack

Compatibility

Designed for use with 1/4 inch bolt assemblies. Suitable as an OEM-style replacement or new-installation Belleville disc spring in mechanical systems requiring a 0.75 inch OD conical washer spring.

Installation Notes

Installation is typically performed by mechanical technicians or industrial maintenance professionals. Ensure all fasteners and mating surfaces are clean and free of debris before seating the spring. When stacking multiple disc springs, consult the design specification for series versus parallel orientation, as orientation directly affects deflection and load output. Never exceed the rated deflection to avoid permanent deformation or fatigue failure.
