Gardner Spring MB2000-097 Belleville Disc Spring 2in Od

Product Description

The GARDNER SPRING MB2000-097 is a Belleville disc spring designed to deliver a high load in a compact axial space. This conical washer-style spring has a 2-inch outer diameter, a 1-inch inner diameter, and an overall assembled height (OAH) of 0.145 inches. Manufactured from steel, it provides a rated load of 62.5 pounds at its full deflection of 0.043 inches. Belleville disc springs are used wherever a precise, space-efficient spring force is needed, and are installed by mechanical contractors, millwrights, and maintenance technicians in bolted joint assemblies, valve seats, and clamping fixtures.

This disc spring is suited for use in industrial, commercial, and trade applications where consistent axial preload or vibration dampening is required in tight radial clearances. Its 1-inch bolt size compatibility makes it a direct fit for standard 1-inch fastener assemblies. It is commonly stacked in series or parallel configurations to tune load and deflection characteristics to the specific assembly requirement. HVAC equipment mounting, pump and valve assemblies, and pipe flange connections are typical installation environments.

Key Features

• Steel construction provides durability and resistance to compressive fatigue in cyclic load applications
• 2-inch OD and 1-inch ID sized for 1-inch bolt or shaft assemblies
• 62.5-pound load rating at 0.043-inch deflection provides predictable, measurable spring force
• Low-profile 0.145-inch OAH allows use in space-constrained bolted joints
• Can be stacked in series to increase deflection range or in parallel to increase load capacity

Compatibility

Designed for use with 1-inch bolt size assemblies. Verify OD, ID, OAH, load, and deflection values against your assembly drawings before installation to confirm fitment.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance personnel following the equipment manufacturer's torque and assembly specifications. De-energize, depressurize, or isolate the assembly before disassembling any bolted joint. Use the correct sequence and pattern when torquing fasteners to ensure even load distribution across the disc spring. Do not exceed the rated deflection, as over-compression can permanently damage the spring and compromise joint integrity.
