Applications & Benefits
This wave spring is widely used in automotive transmissions, valve assemblies, pumps, aerospace mechanisms, and industrial machinery where space is limited and consistent axial force is required. The compact design allows you to reduce the overall spring stack height by up to 50% compared to traditional coil springs, saving valuable assembly space. The 304 stainless steel material provides excellent resistance to moisture, chemicals, and high temperatures, making it suitable for harsh operating conditions. By choosing our wave spring, customers benefit from lower inventory costs (one size replaces multiple coil springs), easier installation, and improved reliability.

Frequently Asked Questions (FAQ)
-
What is the tolerance on the inner and outer diameter?
Our standard tolerance is ±0.05mm for ID and OD. Tighter tolerances are available upon request. -
Can this wave spring operate at high temperatures?
304 stainless steel can typically withstand continuous temperatures up to 870°C (intermittent) and 925°C (continuous) in oxidizing environments. For specific duty cycles, please consult us. -
Is the free sample fully representative of production quality?
Yes, free samples are made from the same batch material and process as mass production. You can test fit and performance. -
What is the typical load capacity for this size?
Load capacity depends on wave height and number of waves. For standard design, it can provide a force of approximately 5-15N. We can provide detailed force-deflection curves upon request. -
Do you offer custom wave springs with different dimensions or materials?
Absolutely. We can adjust ID, OD, wire diameter, wave count, and even use other stainless steel grades (e.g., 316) or spring steel. Minimum order quantity may apply. -
How long does shipping take to the United States?
Typical delivery time is 15-25 days via sea freight from Tianjin or Qingdao. Express samples (DHL/UPS) take 5-7 working days. -
What is the warranty coverage?
Our 1-year warranty covers manufacturing defects. If you find any issue during normal use, we will replace or refund the affected items.
