Value Collection BWSI056-050BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI056-050BX is a Belleville disc spring designed to provide controlled axial load and deflection in bolted joint and mechanical assembly applications. This conical washer-style spring stores and releases energy under compression, making it well suited for maintaining clamp load, compensating for thermal expansion, and preventing fastener loosening over time. With an inside diameter of 0.591 inches and an outside diameter of 0.866 inches, this spring is sized for 9/16-inch bolt applications. Constructed from steel, it offers the durability and load-bearing capacity expected in industrial and mechanical service environments.

This Belleville disc spring is used in mechanical assemblies where a compact, high-load spring element is needed in a limited axial space. Typical applications include bolted flanges, valve assemblies, clutch mechanisms, and precision equipment requiring consistent preload. It is installed by maintenance technicians and mechanical assemblers working on industrial machinery, fluid handling systems, and structural fastening applications where vibration resistance and load retention are critical.

Key Features

• Inside diameter of 0.591 inches fits 9/16-inch bolt sizes
• Outside diameter of 0.866 inches for compact radial footprint
• Steel construction provides reliable load-bearing and long service life
• Conical disc design delivers high spring force in minimal axial space
• Suitable for stacking in series or parallel to adjust deflection and load

Compatibility

Designed as a replacement or supplemental Belleville disc spring for 9/16-inch bolt applications in industrial mechanical assemblies requiring a 0.591-inch ID and 0.866-inch OD spring element.

Installation Notes

Installation should be performed by a qualified technician familiar with mechanical fastening and spring assembly practices. De-energize or depressurize the equipment before disassembling any bolted joint or spring stack. When stacking multiple disc springs, orientation affects load and deflection characteristics — consult the assembly drawing or engineering specification for the correct stacking arrangement. Do not exceed the designed deflection limit for this spring during installation.
