Gardner Spring MB0187-007 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0187-007 is a Belleville disc spring engineered for high-load applications in compact assemblies. This conical washer-style spring delivers 270 pounds of load at full deflection of 0.032 inches, making it well suited for applications that demand precise, repeatable clamping force in a very small footprint. The outer diameter measures 0.187 inches, the inner diameter measures 0.093 inches, and the overall assembled height measures 0.013 inches. Constructed from steel, this disc spring is intended for installation by mechanical technicians, maintenance engineers, and precision assembly professionals working with small fastener and spring stack configurations.

This Belleville disc spring is used in residential and light industrial mechanical assemblies where axial load must be maintained within tight dimensional constraints. Typical applications include valve assemblies, electrical connector preloading, fastener joint tension maintenance, and vibration damping stacks. Its 3/32 inch bolt size compatibility makes it a direct fit for small-bore fastener assemblies where standard coil springs cannot provide the necessary load density. Technicians often stack multiple disc springs in series or parallel to tune load and deflection characteristics to application requirements.

Key Features

• 270 pound load capacity at 0.032 inches of deflection
• Compact 0.187 inch outer diameter fits tight bore and fastener assemblies
• Steel construction for durability under cyclic compressive loading
• Compatible with 3/32 inch bolt size configurations
• Low overall height of 0.013 inches enables use in space-constrained stack designs

Compatibility

Designed for use with 3/32 inch bolt size fastener assemblies. Consult application load-deflection requirements before specifying series or parallel spring stacks.

Installation Notes

Installation is typically performed by mechanical assembly technicians or maintenance professionals. Ensure all equipment is de-energized or depressurized before disassembling the fastener joint or valve assembly. Disc springs are sensitive to surface condition and orientation - inspect seating surfaces for burrs or corrosion before installation. Stacking orientation affects load and deflection behavior; refer to the assembly drawing or engineering specification for correct orientation.
