As a trusted Belleville washers supplier in the UK, Stephens Gaskets understands that when it comes to heavy-duty applications, standard washers simply won’t do. From high-stress mechanical systems to vibration-prone assemblies, Belleville washers – also known as conical spring washers – are engineered for the job.
Their unique shape allows them to manage extreme loads, absorb shock, and prevent bolt loosening under stress. But what really makes them stand out in demanding conditions? This guide gives you a detailed yet practical overview, showing how Belleville washers work, when to use them, and why custom solutions matter.
If you’re considering whether to buy Belleville washers for a critical project or need bespoke Belleville washers cut to exact spec, this is the place to start.
What Is a Belleville Washer?
A Belleville washer is a disc-shaped washer formed into a conical shape. When compressed, it flattens and generates a strong spring force.
This force allows it to:
- Support high loads
- Maintain tension
- Resist loosening from vibration or thermal cycling
Also known as conical spring washers, they’re often used where bolt pre-load is essential and standard flat washers fall short.
How Belleville Washers Handle High Loads
The load-bearing strength of a Belleville washer lies in its geometry. When compressed, the conical shape acts like a spring, exerting a return force.
This means Belleville washers:
- Maintain consistent clamping force
- Distribute loads evenly
- Reduce fatigue in bolted joints
They’re ideal high load washers for sectors like:
- Aerospace
- Automotive
- Construction equipment
- Power generation
At Stephens Gaskets, we manufacture Belleville washers in a range of alloys and dimensions, or as custom Belleville washers made to exact drawings or tolerances.
The Advantages of Using Belleville Washers
1. Exceptional Load Handling
Unlike flat washers, Belleville washers absorb and manage dynamic forces. This makes them perfect for applications that involve shifting loads or intense mechanical vibration.
2. Vibration Resistance
One of the biggest causes of mechanical failure is loosening due to vibration. Belleville washers act like shock absorbers, maintaining preload and preventing fastener back-out.
3. Compact Design
They deliver strong performance in tight spaces, thanks to their compact and efficient form factor.
4. Stacking Options
You can stack Belleville washers in series or parallel to adjust force or deflection as needed – creating a versatile and adjustable solution.
Applications That Rely on Belleville Washers
Industrial & Construction Equipment
Ideal for securing bolted joints in rotating machinery and load-bearing systems.
Railway & Transportation
Used in couplings, brakes, and assemblies subject to dynamic movement and constant vibration.
Wind and Solar Power
Ensures fastening integrity under cyclical stress and temperature variation.
Aerospace and Defence
Precision and high-load capabilities make them suitable for mission-critical parts.

Key Considerations When Specifying Belleville Washers
When deciding what type of washer to use, ask the following:
- What is the load range expected?
- Will the washer need to accommodate thermal expansion?
- Is the fastener under constant vibration or stress?
- Is space limited in the assembly?
- Do I need corrosion-resistant materials?
These factors help determine if a standard washer will work – or if a custom Belleville washer is required.
Frequently Asked Questions
1. What’s the difference between Belleville washers and standard spring washers?
Belleville washers have a conical shape, giving them higher load-bearing capacity and better tension retention than flat or wave spring washers.
2. Can Belleville washers be reused?
Yes, if within their working deflection range. However, repeated overloading can fatigue the material over time.
3. What sizes are available?
We supply standard and custom Belleville washers from 3mm up to 300mm outer diameter. We can cut to your specifications.
4. What industries benefit most from Belleville washers?
Any sector requiring secure fastening under high stress, vibration, or thermal movement – especially aerospace, automotive, and renewable energy.
