Value Collection BWSI050-100BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI050-100BX is a Belleville disc spring designed to deliver axial load and deflection control in bolted assemblies, fastener stacks, and mechanical preload applications. This conical washer-style spring measures 0.512 inches inner diameter, 0.709 inches outer diameter, and 0.067 inches overall height. Constructed from steel, it is suited for use wherever consistent spring force and vibration dampening are required in a compact footprint. Maintenance technicians and assembly professionals handling hardware in HVAC equipment, pump assemblies, valves, and similar mechanical systems install this type of spring as part of a fastener stack or bearing preload arrangement.

This disc spring is sized for 1/2-inch bolt applications. It fits into bolt and fastener assemblies across residential and light commercial mechanical systems, including compressor mounting stacks, valve bodies, and motor mounting hardware where controlled axial preload and vibration isolation are needed. The compact outer diameter of 0.709 inches and low profile height make it appropriate for tight clearance applications. Sold in minimum order quantities of 100, this part is intended for service shops and contractors maintaining hardware inventories for ongoing maintenance and repair work.

Key Features

• Conical disc spring design provides consistent axial load in compact bolt stack configurations
• 0.512-inch inner diameter sized for standard 1/2-inch bolt applications
• 0.709-inch outer diameter with 0.067-inch overall height for low-profile fitment
• Steel construction for durability in mechanical and HVAC equipment assemblies
• Sold in multiples of 100 for shop and field inventory restocking

Compatibility

Designed as a standard-profile Belleville disc spring for 1/2-inch bolt assemblies in mechanical, HVAC, plumbing, and industrial equipment applications requiring controlled axial preload.

Installation Notes

Belleville disc springs are installed by mechanical technicians as part of fastener or bearing preload stacks. De-energize and depressurize the equipment before disassembly. Springs may be stacked in series to increase deflection range or in parallel to increase load capacity. Do not exceed the manufacturer-rated deflection for the spring stack, and verify stack orientation before torquing fasteners.
