JB/T 7590 Black Oxide Carbon Steel Wave Washer Zinc Plated 65Mn Steel Curved Wave Spring Washer for Electric Motors

Corrugated elastic washers are made of thin metal sheets (such as stainless steel, carbon steel or copper alloy) stamped into continuous waves, forming a ring structure with multiple peaks and troughs.
Anti-loosening: Elastic deformation to counteract loosening of bolts/nuts caused by vibration or impact.
Elastic compensation: adapt to the small deformation of the connector or thermal expansion and contraction.
Dispersion pressure: Increase the contact area and reduce the pressure loss on soft materials (such as plastics).
Shock absorption and noise reduction: Absorb mechanical vibration and reduce noise (such as automotive engine components).
Application scenario:
Automotive industry: transmission, engine support and other vibration frequent parts.
Electronic equipment: The circuit board is fixed to avoid rigid connection damage components.
Aerospace: Lightweight and high temperature and fatigue resistant fastening scenarios.
Industrial machinery: sealing and pressure buffering of pump valves and pipe flanges.
