Value Collection BWSI062-050BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI062-050BX is a Belleville disc spring designed for applications requiring controlled axial load and deflection in a compact form factor. Also known as a conical washer spring, this part generates high spring force over a short travel distance. It is made from steel, giving it durability under repeated loading cycles. The inner diameter measures 0.669 inches and the outer diameter measures 0.945 inches, sizing it for use with 5/8-inch bolt assemblies. Mechanical assemblers, millwrights, and maintenance technicians typically install these springs in bolted joints, valve assemblies, and precision clamping fixtures.

Belleville disc springs like the BWSI062-050BX are used across industrial and mechanical applications where bolt preload must be maintained over time. Common installations include flange bolting, pressure relief valves, clutch assemblies, and vibration-dampening stacks. They are well suited for residential and commercial mechanical systems where thermal expansion and contraction can cause fastener loosening. Multiple springs can be stacked in series or parallel to adjust load and deflection characteristics for the specific assembly requirement.

Key Features

• Steel construction for high load capacity and long service life under cyclic stress
• 0.669 inch inner diameter fits 5/8-inch bolt assemblies
• 0.945 inch outer diameter suits compact fastener joint designs
• Conical disc geometry delivers high spring force over minimal deflection travel
• Stackable in series or parallel configurations to tune load and deflection

Compatibility

Designed as an OEM-style replacement or supplemental component for bolted joint assemblies requiring a 5/8-inch bolt size Belleville disc spring with a 0.669 inch ID and 0.945 inch OD.

Installation Notes

Installation is typically performed by a millwright, mechanical assembler, or maintenance technician. Before servicing any assembly, relieve all load, pressure, or tension from the joint and follow applicable lockout/tagout procedures. Ensure the mating surfaces are clean and free of burrs before seating the spring. Do not exceed the rated deflection of the spring, as overloading a Belleville disc spring past its flat position can cause permanent deformation or fracture.
