Gardner Spring MB0250-009 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0250-009 is a Belleville disc spring designed to deliver high load capacity in a compact, stacked or single-seat configuration. With an outer diameter of 0.25 inches, an inner diameter of 0.125 inches, and an overall height of 0.017 inches, this spring is precision-formed from steel for consistent performance under compressive load. Rated at 41,122.1 pounds load at full deflection, it is engineered for applications where significant force must be managed within a very small footprint. Maintenance technicians and mechanical assemblers working in HVAC equipment, precision machinery, and industrial fastener assemblies are the primary installers.

This Belleville disc spring is suited for use in mechanical assemblies that require controlled preload, vibration dampening, or consistent clamping force. Its 1/8-inch bolt size compatibility makes it a fit for small-fastener applications across residential and light commercial HVAC equipment, valve assemblies, pump housings, and similar mechanical systems. The 0.06-inch deflection rating allows for precise load management within tightly toleranced assemblies. Multiple springs can be stacked in series or parallel to adjust load and deflection characteristics to match specific application requirements.

Key Features

• High load capacity of 41,122.1 pounds at full deflection in a 0.25-inch OD form factor
• Steel construction for durability under repeated compression cycling
• 0.06-inch deflection rating supports precise preload control
• Compatible with 1/8-inch bolt size fastener assemblies
• Compact geometry allows stacking in series or parallel for tunable load-deflection curves
• Overall height of 0.017 inches fits tight axial clearance constraints

Compatibility

Designed for use with 1/8-inch bolt size assemblies. Suitable as a replacement or supplemental disc spring in mechanical and HVAC component assemblies requiring a 0.25-inch OD Belleville spring.

Installation Notes

Installation is typically performed by licensed HVAC technicians, mechanical assemblers, or maintenance professionals. De-energize and relieve all system pressure before disassembling any spring-loaded component. Use appropriate hand tools and follow equipment manufacturer torque and preload specifications when seating disc springs. Stacking orientation affects load and deflection output, so verify the stack arrangement against assembly drawings before final installation.
