Disc spring washer work better than flat washers because they can automatically adjust when the joint starts to loosen, keeping the tension tight without needing to retighten by hand. Their cone shape lets them bend a bit under pressure, turning vibration into small elastic movements instead of letting the bolt spin. This helps cut down on rust and wear where the threads meet.

Compared to split lock washers, curved ones push down more evenly, so disc spring washers are less likely to damage the surface they’re on. Most of the time, you can reuse them too,just make sure they still have their curve and springiness after taking them apart.

Quality Standards

Good-quality disc spring washer follow international standards like DIN 6796, ISO 10664, and ASME B18.22.1, so they work with fastener systems worldwide. For aerospace use, there are versions that meet strict military or aviation specs (NASM or MIL-SPEC).

As a professional fastener manufacturer, Xiaoguo® can provide test reports showing how much load they can handle, how well they resist salt spray, and how many cycles they can take before wearing out. Certifications like ISO 9001 ensure they’re made consistently well, even in big production runs.

If you need custom disc spring washers, engineers use computer analysis (FEA) to simulate how they’ll perform under the specific stresses of the application. This makes sure they’re reliable in important jobs where failure isn’t an option.

FAQ

Q: How are disc spring washer different from Belleville washers or wave washers?

A: All three are spring-style washers, but they have different designs. Disc spring washer have a single curved shape (one bump and one dip), which makes them simpler and cheaper for moderate loads. Belleville washers are cone-shaped,they can handle more weight and you can stack them to adjust how much spring force they give. Wave washers, on the other hand, have multiple small waves around the edge to spread out the load.

Disc spring washer work best in lighter setups where you need to resist vibration without complicated math,like in electronics or everyday products. If you’re dealing with heavy machinery that needs to handle extreme loads, Belleville washers are a better pick. Wave washers are more about even load distribution in tight spaces. The choice comes down to how much space you have, how much force you need, and the environment they’ll be in.
