S-90391A153 0.601" ID x 1.156" OD ANSI/ABMA 8.2 Spring Lock Washers for Slotted Bearing Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through the conical spring lock design that maintains constant tension under dynamic loads
• Enhanced locking security with external teeth that bite into mating surfaces, preventing screw loosening in high-vibration environments
• Precision compatibility with 0.586"-32 screws and chamfered bearing nuts for seamless integration into existing assemblies
• Durable steel construction ensures long-term reliability and consistent performance in demanding industrial applications
• Standardized dimensions (0.601" ID × 1.156" OD) guarantee proper fit and function according to ANSI/ABMA 8.2 specifications
• Environmental compliance with RoHS 3 and REACH regulations for safe use in global industrial markets
• Optimized load distribution through conical shape that compensates for thermal expansion and surface irregularities

Professional Applications & Engineering Value

This external tooth conical spring lock washer delivers critical vibration-resistant performance in mechanical systems where fastener integrity is paramount. The steel construction combined with the conical spring lock washer shape creates continuous spring tension that counters loosening forces in high-vibration environments like heavy machinery, automotive assemblies, and industrial equipment. The external tooth configuration provides superior biting action into both the bearing nut and mounting surface, creating a positive locking mechanism that outperforms flat washers. Engineered to ANSI/ABMA 8.2 standards, this washer ensures reliable performance with 0.586"-32 screws and chamfered bearing nuts, making it ideal for precision applications requiring maintained clamp load and resistance to rotational loosening.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 0.601" ID, 1.156" OD, and 0.172" overall height with external tooth configuration. Manufactured to meet ANSI/ABMA 8.2 standards for dimensional accuracy and performance requirements. 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 worldwide. Designed specifically for use with 0.586"-32 screws and chamfered bearing nuts according to established industry specifications.
