Gardner Spring MB1750-057 Belleville Disc Spring

Product Description

The GARDNER SPRING MB1750-057 is a Belleville disc spring engineered for high-load applications in compact spaces. This conical washer-style spring delivers 4452.57 pounds of load at full deflection of 0.2098 inches, making it well suited for bolted joint assemblies, valve stacks, and mechanical preload systems. With a 1.75-inch outer diameter and a 0.88-inch inner diameter, the MB1750-057 fits 7/8-inch bolt sizes. Overall assembled height measures 0.114 inches. Mechanical technicians, industrial assemblers, and maintenance professionals install these springs where precise axial load and vibration dampening are required.

Belleville disc springs of this type are used across a wide range of industrial and mechanical applications, including pipe flanges, pressure vessels, clutch assemblies, and precision machinery. The MB1750-057 is appropriate for both single-spring and stacked configurations depending on load and deflection requirements. Stacking in parallel increases load capacity while stacking in series increases total deflection travel. This part is sold in packages of 12 with a minimum order quantity of 1 package.

Key Features

• 4452.57-pound load capacity at rated deflection for high-force applications
• 0.2098-inch deflection travel provides controlled axial compression
• 1.75-inch outer diameter fits 7/8-inch bolt size hardware
• 0.88-inch inner diameter for centered bolt clearance
• Compact 0.114-inch overall height allows stacking in tight assemblies
• Steel construction for durability under repeated load cycling

Compatibility

Designed for use with 7/8-inch bolt size applications. Suitable for single or stacked Belleville spring configurations in industrial mechanical assemblies requiring high axial load in a low-profile form factor.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with spring stack assemblies and bolted joint specifications. Ensure all load-bearing components are de-energized and depressurized before disassembly. Verify correct spring orientation - conical face direction affects load and deflection characteristics in stacked arrangements. Consult applicable ASME or equipment manufacturer torque and preload specifications for the specific joint being assembled.
