Value Collection BWSI0-8-100BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI0-8-100BX is a steel Belleville disc spring designed for applications requiring a compact, high-load fastening element in a minimal axial space. Also known as a conical washer spring, this component stores and releases energy under compressive load, making it well suited for bolt and fastener assemblies, valve mechanisms, and precision machine components. The inside diameter measures 0.169 inches and the outside diameter measures 0.276 inches, placing it in the small-bore category used in instrumentation and light mechanical assemblies. Installation is typically performed by machinists, maintenance technicians, or assembly line personnel.

This disc spring is used in applications where conventional coil springs cannot fit due to space constraints. Its conical geometry allows stacking in series or parallel to achieve different load and deflection characteristics. Typical install scenarios include bolt preloading, overload protection, vibration damping, and maintaining clamping force under thermal cycling. The small form factor suits precision equipment, valves, and threaded fastener assemblies in both industrial and commercial environments.

Key Features

• Steel construction provides durability under repeated compressive cycling
• 0.169 inches inside diameter and 0.276 inches outside diameter for compact fitment
• Conical disc geometry allows series or parallel stacking for load tuning
• Suitable for bolt preloading, vibration damping, and overload protection applications
• Small form factor fits tight axial spaces where coil springs are not practical

Compatibility

Designed as an OEM-style replacement or new-installation disc spring for threaded fastener assemblies and mechanical subassemblies requiring a 0.169 inches ID, 0.276 inches OD conical washer spring.

Installation Notes

Belleville disc springs are installed by machinists or mechanical technicians as part of fastener or valve assemblies. Before service, de-energize or depressurize the host system as appropriate. Stacking orientation and quantity determine the resulting load and deflection curve — consult the assembly drawing for correct configuration. Do not exceed the rated deflection of the spring stack to avoid permanent deformation.
