S-90464A240 2.4" ID x 3.344" OD ANSI/ABMA 8.2 Spring Lock Washers for Slotted Bearing Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through conical spring design that maintains constant tension under dynamic loads
• Exceptional corrosion resistance with stainless steel construction for harsh industrial environments
• Positive locking action with external tooth configuration that bites into mating surfaces for secure fastening
• Precision dimensional accuracy with 2.4" ID and 3.344" OD ensuring perfect fit for 2.360"-18 screw applications
• Optimized bearing surface contact with chamfered face design that prevents galling and distributes load evenly
• Industry-standard compliance meeting ANSI/ABMA 8.2 specifications for reliable performance in demanding applications
• Environmental responsibility with RoHS 3 and REACH compliance for sustainable manufacturing practices

Professional Applications & Engineering Value

This stainless steel spring lock washer delivers critical engineering solutions for industrial applications where vibration loosening poses significant reliability concerns. The conical shape and external tooth design work synergistically to create a spring-like action that maintains preload while the teeth dig into both the bearing surface and fastener head, preventing rotational slip. Manufactured from corrosion-resistant stainless steel, this washer excels in harsh environments where moisture, chemicals, or temperature variations would compromise ordinary fasteners. Particularly valuable for bearing nut applications requiring ANSI/ABMA 8.2 compliance, this component ensures long-term joint integrity in heavy machinery, industrial equipment, and precision assemblies where maintenance downtime is costly and safety is paramount.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 2.4" inner diameter, 3.344" outer diameter, and 0.249" overall height with external tooth configuration. Manufactured to ANSI/ABMA 8.2 standards for bearing nut applications with chamfered face style. The component maintains dimensional accuracy in the inch system of measurement and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both performance reliability and regulatory adherence for global industrial applications.
