• Precision dimensional compliance with DIN 5406 and DIN 981 standards ensuring reliable fit and performance
• Durable steel construction providing long-lasting service life in demanding industrial environments
• Optimized load distribution with chamfered bearing nut face style reducing stress concentrations
• Environmental compliance meeting RoHS 3 and REACH regulations for safe industrial use
• Easy installation with clearly defined 150mm ID and 205mm OD for quick component alignment

Professional Applications & Engineering Value

This M150 spring lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The external tooth conical design creates multiple biting points that resist rotational movement, while the spring action maintains consistent preload. Manufactured from high-quality steel, this washer excels in heavy machinery, industrial equipment, and automotive assemblies where DIN 5406 compliance ensures dimensional precision and reliable performance. The conical shape provides superior spring characteristics compared to flat washers, making it ideal for bolted connections subject to thermal cycling, dynamic loads, or constant vibration. With 150mm inner diameter and 205mm outer diameter, it accommodates large fastener systems while the external tooth configuration prevents washer rotation during installation and operation.

Specification Summary & Compliance

This spring lock washer features precise dimensions: 150mm inner diameter, 205mm outer diameter, 2.0mm thickness, and 10mm overall height with 16mm tab width and 5mm tab depth. Manufactured to DIN 5406 standards with compatibility for DIN 981 bearing nuts, ensuring dimensional accuracy and functional reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental safety requirements for industrial applications across global markets.
