Gardner Spring MB1262-060 Belleville Disc Spring

Product Description

The GARDNER SPRING MB1262-060 is a Belleville disc spring engineered for high-load applications in compact axial spaces. This conical washer-style spring generates significant clamping or cushioning force with minimal deflection travel. It measures 1.262 inches outer diameter, 0.505 inches inner diameter, and 0.091 inches overall height, with a rated deflection of 0.008 inches and a load capacity of 263.03 pounds at full deflection. Constructed from steel, it delivers consistent spring force under cyclic loading conditions. Mechanical contractors, maintenance technicians, and assembly professionals install these springs in bolted joints, valve assemblies, and precision fastening applications where controlled preload is required.

This Belleville disc spring is sized for use with a 1/2 inch bolt. It is well suited for industrial fastening, pipe flange connections, pressure vessel assemblies, and mechanical equipment requiring reliable axial load compensation. The compact geometry allows stacking in series or parallel configurations to tune load and deflection characteristics for a specific joint requirement. Typical applications span commercial HVAC equipment, plumbing valve bodies, and general mechanical assemblies where maintaining bolt preload over time is critical.

Key Features

• 1.262 inches outer diameter with 0.505 inches inner diameter sized for 1/2 inch bolts
• 0.091 inches overall height for low-profile axial spring force
• 263.03 pound load rating at 0.008 inches deflection for precise preload control
• Steel construction for durability under cyclic and static loading
• Stackable design allows series or parallel configurations to adjust load and deflection

Compatibility

Designed for use with 1/2 inch bolt sizes. Suitable as an OEM-style replacement or new-installation Belleville disc spring in mechanical assemblies requiring this dimensional specification.

Installation Notes

Installation should be performed by a qualified mechanical technician or pipefitter familiar with bolted joint and spring preload requirements. Ensure the mating surfaces are clean and free of burrs before seating the spring. When stacking multiple disc springs, confirm orientation relative to desired load and deflection characteristics before torquing fasteners. Always depressurize or de-energize the assembly before disassembly or replacement of any spring component.
