Split Ring Lock Washer

In industrial heavy machinery, Split Ring Lock Washer are a common way to keep bolts from loosening. When you tighten the fastener, the split lock washer gets pressed flat. It bounces back naturally, creating continuous outward force. At the same time, its sharp edges cut into the metal surface, preventing the bolt from shaking loose over time.

【1】Core advantage

（1）It holds bolts firmly in place with continuous pushing and surface grip.

（2）Simple to install, and no special tools are required.

（3）Fits most standard bolts and nuts. It’s made to common standards such as DIN 127, making stock management straightforward.

（4）Split Ring Lock Washer are high in durability. They are heat treated to reach a hardness of 370–470 HV. This lets them stand up to heavy pressure and frequent vibration on heavy machinery, ensuring long service life.

(5) You can choose different surface finishes, like standard zinc plating or a zinc-aluminum coating (Dacromet). That way, you get the right level of rust protection for whatever conditions the washer will face.

【2】Application Examples

(1) Shredders and crushers – In this kind of equipment, the washers are used on important bolts to stop them from loosening because of unbalanced spinning and constant vibration.

(2) Heavy mobile machinery – For construction equipment like excavators, these Split Ring Lock Washer help spread out the dynamic loads and keep the key connection points tight.

(3) Energy and mining equipment – These washers fit for wind turbines, solar setups and other clean energy devices, as well as heavy mining machines. They fasten bolts firmly, and stay locked even with frequent vibration and heat expansion.

(4) General machinery – Widely applied on pumps, compressors and common mechanical parts. They can deal with equipment vibration and external force pressure in daily operation.

【3】Installation Tips

When installing, place the Split Ring Lock Washer in between the bolt, screw or nut and the part you’re securing. Just make sure its sharp edge sits right against the metal surface. Then tighten it to the torque spec to get a good fit. These washers are meant for one-time use only – don't reuse them. If you do, the clamping force drops, which could cause safety issues and make it less effective.
