Perfect for bearing assemblies

These wave washers fit perfectly in our motor bearing housings. The 65Mn steel holds its spring tension well even after multiple compressions. Highly recommended for industrial applications.

Reliable for vibration damping

Installed these in our conveyor system motors to reduce noise and vibration. They have performed flawlessly for six months now without any signs of fatigue or corrosion.

Good quality, fast shipping

Ordered the M12 size for a machinery repair project. The finish is consistent and the dimensions are accurate. Took off one star because the packaging was slightly damaged, but the parts were fine.

Great value for bulk orders

Purchased the full range from M4 to M20 for our workshop inventory. The price point is excellent for this grade of steel. Just ensure you check the specific thickness for your tolerance requirements.

Excellent spring load consistency

We use these for preload adjustment in high-speed spindles. The three-peak design provides a very smooth load curve compared to standard Belleville washers. Will order again.

5 FAQ

Q: Is the M118 size available in stock or is it made to order?

A: The M118 size is typically a made-to-order item due to its specialized application. Current lead time is approximately 10-14 business days.

Q: Are these washers suitable for outdoor applications exposed to rain?

A: While the black oxide coating offers some resistance, we recommend applying additional grease or using stainless steel variants for prolonged exposure to harsh outdoor elements to prevent rust.

Q: What is the maximum operating temperature for the M45 size?

A: All sizes in this series, including M45, are rated for continuous operation up to 200°C. Beyond this temperature, the tempering of the 65Mn steel may be affected.

Q: Do these come with a material certification report?

A: Yes, a mill test certificate (MTC) confirming the 65Mn steel composition and hardness testing is included with every bulk order over 500 units.

Q: Can I mix different sizes in a single order to get the bulk discount?

A: Yes, you can mix sizes within the same material category. Please select the 'Mixed Size Pack' option at checkout or contact our sales team for a custom quote.
