Professional Applications & Engineering Value

This M110 spring lock washer delivers critical engineering solutions for vibration-prone applications where fastener security is paramount. The conical shape with external teeth creates multiple biting points that dig into both the bearing surface and nut, effectively resisting rotational forces that cause conventional fasteners to loosen. Manufactured from high-grade steel, this metric spring washer maintains its spring properties under repeated loading cycles, making it ideal for heavy machinery, automotive assemblies, and industrial equipment where vibration resistance directly impacts operational safety and maintenance intervals. The specific design compatibility with chamfered bearing nuts (DIN 981) ensures optimal load transfer and prevents damage to mating components, while the standardized DIN 5406 compliance guarantees consistent performance across your fastener systems.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions with 110mm inner diameter, 154mm outer diameter, and 6.5mm overall height. Manufactured according to DIN 5406 standards for dimensional accuracy and performance requirements. The external tooth configuration provides maximum locking effectiveness while maintaining compatibility with chamfered bearing nuts meeting DIN 981 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications across various sectors.
