Gardner Spring MB0250-009-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0250-009-S is a Belleville disc spring manufactured from stainless steel and engineered for high-load applications in compact assemblies. Also known as a conical washer spring, this part delivers significant axial load in a small footprint. It measures 0.25 inches in outer diameter and 0.125 inches in inner diameter, with an overall assembled height of 0.017 inches. At full rated deflection of 0.049 inches, the spring delivers a load of 1,265.4 pounds. These characteristics make it well suited for precision fastening, preloading, and vibration-dampening applications across mechanical and electromechanical systems. Licensed mechanical professionals and precision assembly technicians are the typical installers.

This Belleville disc spring is used in applications requiring consistent axial force within tight dimensional constraints. Its stainless steel construction resists corrosion, making it appropriate for HVAC equipment assemblies, plumbing valve components, electrical panel hardware, and other environments where moisture or chemical exposure is a concern. The 1/8-inch bolt size compatibility makes it a direct fit for fastener stacks in standard small-bore assemblies. Package quantity is 12 units per pack with a minimum order quantity of 1.

Key Features

• Stainless steel construction for corrosion resistance in wet or chemically active environments
• 1,265.4-pound load capacity at 0.049-inch deflection for high-force-density applications
• 0.25-inch outer diameter and 0.125-inch inner diameter for compact installation envelopes
• Compatible with 1/8-inch bolt sizes for standard small-bore fastener stacks
• Conical disc geometry provides consistent, repeatable spring force under axial load

Compatibility

Designed for use with 1/8-inch bolt sizes in standard Belleville disc spring applications. Suitable as an OEM-style replacement or new installation component in mechanical assemblies requiring conical washer springs of this dimensional profile.

Installation Notes

Installation is typically performed by licensed mechanical or electromechanical technicians. Power down or de-energize the assembly before servicing any components in the fastener stack. Belleville disc springs are directionally sensitive - confirm proper orientation per the equipment manufacturer's documentation before torquing fasteners. Do not exceed the rated deflection value, as over-compression can permanently deform the spring and reduce load capacity.
