Split lock washers, also known as split spring washers, are essential components for maintaining bolt tension and preventing loosening under vibration. These washers function by applying a continuous spring force against the nut or bolt head, compensating for material松弛 and thermal expansion. They are a specific type of spring washer, distinct from other designs like the corrugated spring washer. For applications demanding reliable, vibration-resistant fastening, split spring lock washers are a preferred engineering solution. Their simple yet effective split-ring design provides superior locking action compared to flat washers. Explore our range of high-quality Split Spring Washers and other Spring Washers to find the perfect fit for your project's requirements. While a Corrugated Spring Washer offers a different load distribution profile, the split lock washer remains the go-to for high-vibration environments.
The split lock washers from our inventory are manufactured to the highest industry standards, ensuring consistent performance and longevity. We offer a comprehensive selection of sizes and materials to meet diverse application needs, from general machinery to heavy-duty industrial equipment. The primary function of a split lock washer is to create a spring-like action that keeps the fastener tight. As the nut is tightened, the ends of the washer are forced flat against the bearing surface. This action stores energy in the washer, which exerts a counter-force, maintaining clamp load and preventing the nut from rotating loose. The design of the split lock washer is particularly effective in applications subject to dynamic loads, thermal cycling, and significant vibration.
