Gardner Spring MB1875-057 Belleville Disc Spring

Product Description

The GARDNER SPRING MB1875-057 is a Belleville disc spring engineered for high-load applications in a compact axial footprint. With a 1.875-inch outer diameter, a 0.63-inch inner diameter, and an overall assembled height of 0.115 inches, this conical washer-style spring delivers up to 6,127.6 pounds of load at full rated deflection of 0.008 inches. Constructed from steel, it is suited for use wherever controlled preload, vibration damping, or axial thrust management is required. Mechanical contractors, millwrights, and industrial maintenance technicians are the primary installers of this component type.

This disc spring is sized for a 5/8-inch bolt and is commonly used in bolted flange assemblies, valve actuators, pump housings, and mechanical couplings across industrial, commercial, and OEM equipment. The combination of small deflection and high load output makes it appropriate for stacking configurations where preload precision matters. Package quantity is 6 units per pack, with a minimum order quantity of 1 pack.

Key Features

• High load output of 6,127.6 pounds at 0.008 inches of deflection
• 1.875-inch outer diameter with 0.63-inch inner diameter for 5/8-inch bolt fitment
• Overall assembled height of 0.115 inches for low-profile stacking
• Steel construction for durability under sustained compressive load
• Sold in packs of 6 units

Compatibility

Designed for use with 5/8-inch bolt assemblies in industrial and commercial mechanical applications requiring Belleville-style conical disc spring preloading.

Installation Notes

Belleville disc springs are installed by millwrights, mechanical contractors, or industrial maintenance technicians as part of bolted joint or actuator assemblies. Always de-energize and depressurize the system before disassembly. Springs may be stacked in series to increase deflection travel or in parallel to increase load capacity - verify the stacking orientation against the assembly specification before installation. Inspect mating surfaces for burrs or debris that could affect seating and load distribution.
