Gardner Spring MB1500-062-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB1500-062-S is a Belleville disc spring engineered for high-load applications in compact axial spaces. It measures 1.5 inches outer diameter with a 0.755 inch inner diameter and an overall height of 0.102 inches. Constructed from stainless steel, this conical washer-style spring delivers 538.1 pounds of load at its rated deflection of 0.0252 inches. Belleville disc springs are used across industrial, mechanical, and fluid system assemblies wherever a stiff, space-saving spring element is required. Installation is performed by mechanical assemblers, maintenance technicians, and pipefitters working on bolted joints, valve actuators, and precision fastening applications.

This disc spring is suited for use in bolted flange assemblies, valve packing glands, bearing preload applications, and vibration-dampening stacks where consistent axial force is required in a minimal footprint. It is sized for 3/4 inch bolt applications. Stainless steel construction makes it appropriate for environments with moisture exposure or moderate corrosive conditions. Individual springs can be stacked in series to increase deflection range or in parallel to increase load capacity, depending on assembly requirements.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• High load capacity of 538.1 pounds at 0.0252 inches of rated deflection
• Compact profile: 1.5 inches OD, 0.755 inches ID, and 0.102 inches overall height
• Sized for 3/4 inch bolt applications
• Stackable design allows customization of load and deflection characteristics

Compatibility

Designed for use in 3/4 inch bolt assemblies requiring a Belleville disc spring with 1.5 inches OD and 0.755 inches ID. Consult stack configuration guidelines for multi-spring series or parallel arrangements.

Installation Notes

Installation is typically performed by qualified mechanical technicians or pipefitters. Depressurize and de-energize the assembly before disassembly or spring replacement. Ensure mating surfaces are clean and free of burrs to avoid uneven load distribution. Follow applicable ASME or equipment manufacturer torque specifications for the surrounding bolted joint.
