Industrial Belleville Spring Washers: Over 50 Years Of Experience

American Belleville is a leading manufacturer of Belleville spring washers, delivering reliable, precision-engineered bolting solutions across demanding global industries. Our washers provide consistent bolt preload, absorb vibration, and maintain joint integrity where performance under stress is non-negotiable.

From electrical transmission to deep-well energy production, discover how American Belleville supports critical applications across five key sectors.

Electrical Connections

Modern power grids require durable, low-resistance connections that resist thermal expansion. American Belleville manufactures high-performance Belleville spring washers designed to maintain constant clamping pressure in electrical assemblies through continuous temperature cycles.

Key applications include:

  • Pole line hardware and transformers
  • High-voltage transmission lines
  • Industrial circuit breakers
  • Power semiconductor modules

Fastener Distribution

Fastener distributors supply the backbone for aerospace, automotive, construction, and heavy machinery industries. American Belleville supports distributors with a full catalog of Belleville spring washers, flange washers, load washers, and disc springs.

We streamline your supply chain with:

  • Vendor Managed Inventory (VMI) and Just-In-Time (JIT) delivery programs
  • Rapid quote turnarounds and short lead times
  • USA-made inventory ready for immediate shipment

Industrial Hardware

In industrial manufacturing, component failure means immediate downtime. American Belleville supplies industrial distributors and OEMs with precision Belleville spring washers built to protect heavy machinery and fluid control systems.

Common applications include:

  • Commercial and industrial valves
  • Heavy-duty mechanical actuators
  • High-torque flexible couplings

Valve Applications & Live Loading

Valves control vital fluid and gas lines where leaks pose severe safety and environmental risks. American Belleville engineers specialized Belleville spring washers specifically designed for dynamic valve packing and live-loading applications.

Our washers maintain continuous load on gland packing seals to prevent fugitive emissions in:

  • Valve live-loading systems
  • Valve packing stems
  • High-cycle valve actuators
  • Critical ball valves

Oil and Gas Applications

The energy sector operates under extreme pressure, high heat, and corrosive environments. American Belleville manufactures high-alloy Belleville spring washers (including Inconel and stainless steel options) engineered to prevent bolt creep and flange leaks under harsh conditions.

Trusted in demanding energy settings:

  • Downhole drilling and completion tools
  • Shell and tube heat exchangers
  • Offshore flange bolting and wellheads
