Value Collection BWSI075-050BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI075-050BX is a Belleville disc spring designed for applications requiring controlled axial load and deflection in a compact profile. Also known as a conical washer spring or disc washer, this component stores and releases energy along its axis, making it useful for bolt load retention, vibration dampening, and preload maintenance in mechanical assemblies. It features a 0.787 inch inner diameter and a 1.181 inch outer diameter, sized for 3/4 inch bolt applications. Steel construction provides the durability and spring rate consistency required in industrial and trade-grade fastening systems.

This disc spring is suited for use in mechanical assemblies where bolt preload must be maintained over time, particularly in applications subject to vibration, thermal cycling, or dynamic loading. Common install scenarios include pipe flanges, valve actuators, motor mounts, and structural fastening points. The 3/4 inch bolt size compatibility makes it a standard fit for a wide range of plumbing, HVAC, and industrial equipment fastening applications. It is typically installed by millwrights, pipefitters, or mechanical technicians working on equipment requiring precise spring force management.

Key Features

• 0.787 inch inner diameter sized for 3/4 inch bolt applications
• 1.181 inch outer diameter for standard conical washer seating
• Steel construction for consistent spring rate and long service life
• Conical disc geometry provides high load capacity in minimal axial space
• Suitable for stacking in series or parallel to adjust deflection and load characteristics

Compatibility

Designed as a standard Belleville disc spring replacement for mechanical assemblies using 3/4 inch fasteners that require axial preload or vibration-dampening washers.

Installation Notes

Install with the correct orientation as specified by the assembly drawing, as reversing or stacking disc springs alters the load-deflection curve. Ensure mating surfaces are clean and free of burrs before seating the spring. Torque fasteners according to the equipment manufacturer's specifications — do not use this spring's dimensions alone to determine clamp load. Wear appropriate PPE when handling springs under compression.
