Stephens Gaskets is a trusted UK manufacturer and supplier of Thrust Washers engineered for performance in high-load, high-speed environments.
Whether you’re working on an automotive engine, a marine gearbox, or industrial pump, our thrust washers are designed to control axial movement and reduce wear.
We offer both Custom Thrust Washers and standard sizes, tailored to your specific assembly, material, and environmental requirements.
What Are Thrust Washers?
Thrust washers are flat, disc-shaped components that absorb axial loads – forces applied along the axis of a rotating shaft. Acting like a bearing, they prevent metal-on-metal contact and maintain spacing between moving parts.
Key Functions:
- Absorb axial (end) forces.
- Minimise friction and wear.
- Maintain component alignment.
- Protect against shaft movement or damage.
Benefits of Thrust Washers
1. Absorbs Axial Loads
Prevents shafts from shifting and maintains mechanical balance during operation.
2. Minimises Friction and Wear
Acts as a buffer between moving parts, reducing metal-on-metal contact and the risk of seizing.
3. Maintains Alignment
Ensures stable component positioning, especially in dynamic environments.
4. Increases Machinery Lifespan
Protects gears, shafts, and housings, reducing maintenance and downtime.
5. Highly Customisable
Available in various materials (steel, bronze, PTFE, graphite, and more) to suit speed, temperature, and lubrication conditions.
6. Cost-Effective
Replacing a washer is significantly cheaper than repairing a crankshaft or gearbox.
7. Easy to Fit
Can be retrofitted into assemblies without major redesigns.
Common Applications for Thrust Washers
1. Automotive & Transport
- Gearboxes and transmissions: Maintain gear alignment and manage end-thrust.
- Crankshaft assemblies: Control engine movement and reduce friction.
- Differentials and steering systems: Prevent wear and maintain smooth rotation.
2. Industrial Equipment
- Pumps and compressors: Absorb axial loads from impellers and shafts.
- Electric motors and generators: Prevent shaft displacement.
- Gear assemblies: Maintain spacing and minimise housing wear.
3. Aerospace & Marine
- Turbine systems and propulsion units: Provide axial stability in high-speed environments.
- Landing gear and steering: Withstand dynamic axial loads.
- Propeller shafts and gear drives: Reduce saltwater-induced wear.
4. Engineering, Automation & Instrumentation
- Lathes and CNC machines: Handle axial pressure in rotating spindles.
- Robotics and automation systems: Control movement in pivot points.
- Precision devices and lab equipment: Maintain alignment in micro-mechanics.
Materials for Thrust Washers by Industry
| Material | Properties | Common Uses |
|---|---|---|
| Mild Steel (CS4, CS70) |
Durable, cost-effective | General gearboxes, jigs, industrial tools |
| Phosphor Bronze | Anti-friction, long-lasting | High-wear systems, rotating assemblies |
| Stainless Steel (304/316) | Corrosion-resistant, hygienic | Food processing, marine, chemical plants |
| PTFE (Teflon) | Self-lubricating, chemically inert | Cleanrooms, dry-running machines |
| Graphite-Composite | High-temp stability, dry lubrication | Furnaces, high-temp rollers |
| Brass | Light-duty, corrosion-resistant | Valves, press machinery |
| Laminated/Composite | Maintenance-free, low-friction surfaces | Automation, high-cycle equipment |
Solving Common Challenges in Mechanical Assemblies
1. Incorrect Material Selection
- Problem: Rapid wear or failure due to mismatch with load, temperature, or lubrication.
- Solution: Stephens Gaskets advises on material selection tailored to your conditions.
2. Load Failure Under Pressure
- Problem: Deformation or cracking under excessive axial loads.
- Solution: Choose thicker, high-strength materials like hardened steel or phosphor bronze.
3. Assembly & Fitting Errors
- Problem: Misalignment during installation or improper seating.
- Solution: Precision machining and clear fitting support reduce assembly risks.
4. Lubrication Gaps
- Problem: Premature wear in parts requiring lubrication.
- Solution: Use PTFE or graphite-based thrust washers for self-lubricating performance.
5. Contaminated Environments
- Problem: Dust, debris, or moisture causes premature scoring.
- Solution: Opt for corrosion-resistant or dirt-tolerant materials like stainless steel.
6. Supply Limitations for Legacy Machines
- Problem: Standard sizes don’t fit outdated equipment.
- Solution: Custom manufacturing services available from Stephens Gaskets.
7. Vibration & Noise
- Problem: Incorrect or worn washers cause rattling or vibrational damage.
- Solution: Maintain tolerances and replace washers proactively.
FAQs
What does a thrust washer do?
It absorbs axial loads, maintains shaft alignment, and prevents wear in rotating assemblies.
Where are thrust washers used?
They are used in gearboxes, pumps, motors, turbines, lathes, and any system that needs to manage axial forces.
Can thrust washers work without lubrication?
Yes. PTFE and graphite composites are designed for dry-running environments.
What's the best material for high-load applications?
Phosphor bronze or hardened steel offer superior performance under heavy-duty conditions.
Can Stephens Gaskets manufacture to my drawing?
Absolutely. We offer bespoke thrust washers to meet exact size, thickness, and material requirements.
Do you offer bulk or trade pricing?
Yes. Volume discounts and trade accounts are available.
How fast can you ship?
Most standard orders ship in 2-5 days. Custom orders typically dispatch in under 10 days.
