Gardner Spring MB0625-022-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0625-022-S is a Belleville disc spring engineered for applications requiring high load capacity in a compact axial footprint. Manufactured from stainless steel, this conical washer-style spring measures 0.625 inches outer diameter and 0.317 inches inner diameter, with an overall assembled height of 0.042 inches. At its rated deflection of 0.0193 inches, the spring delivers a load of 566.52 pounds. The stainless steel construction provides corrosion resistance suited to harsh service environments. This type of spring is typically installed by mechanical technicians, maintenance engineers, or assembly specialists working on precision fastened joints and mechanical subassemblies.

Belleville disc springs of this size are commonly used in bolted flange assemblies, valve seats, bearing preload applications, and vibration-dampening stacks. The 5/16 inch bolt size compatibility makes this spring a practical choice for hardware found in HVAC equipment frames, pump assemblies, compressor mounts, and similar mechanical systems where controlled spring force over a short travel distance is required. The minimum order quantity is 1 unit and the package quantity is 12.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• High load-to-deflection ratio: 566.52 pounds load at 0.0193 inches deflection
• Compact profile with 0.625 inches OD and 0.042 inches overall height
• Compatible with 5/16 inch bolt size hardware
• Can be stacked in series or parallel to tune load and deflection characteristics

Compatibility

Designed for use with 5/16 inch bolt size assemblies. Suitable as an OEM-style replacement or new-installation disc spring in mechanical systems requiring a 0.625 inches OD Belleville-type conical washer spring.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with spring stack assemblies and fastener torque procedures. Always de-energize and depressurize the host system before disassembling any bolted joint or valve assembly. When stacking multiple Belleville springs, verify the intended series or parallel orientation against the load-deflection requirement before tightening. Do not exceed the rated deflection of the spring during installation or operation.
