S-90464A170 1.193" ID x 1.922" 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 design that maintains constant tension under dynamic loads
• Enhanced locking security with external teeth that bite into mating surfaces, preventing loosening in high-vibration applications
• Corrosion-resistant construction using stainless steel material for extended service life in harsh industrial environments
• Precision compatibility with 1.173"-18 screw sizes and chamfered bearing nuts for seamless integration into existing assemblies
• Reliable performance standardization through ANSI/ABMA 8.2 compliance, ensuring consistent quality and dimensional accuracy
• Environmental responsibility with RoHS 3 and REACH compliance, meeting international regulatory requirements
• Optimized load distribution from the conical shape that compensates for settlement and thermal expansion in bearing applications

Professional Applications & Engineering Value

This stainless steel spring lock washer delivers exceptional engineering value in demanding industrial applications where vibration-induced loosening poses significant reliability concerns. The conical shape with external teeth creates a dual-action locking mechanism: the spring tension maintains preload while the external teeth provide positive mechanical locking against rotation. Specifically engineered for bearing nut applications with chamfered face compatibility, this washer prevents bearing preload loss in rotating equipment, machinery assemblies, and automotive systems. The 1.193" ID and 1.922" OD dimensions ensure precise fit with standard components, while the stainless steel construction offers corrosion resistance in environments exposed to moisture, chemicals, or temperature variations. This combination of features makes it an ideal solution for maintaining joint integrity in high-vibration industrial fastening scenarios where reliability is paramount.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 1.193" inner diameter, 1.922" outer diameter, and 0.054" thickness with external tooth configuration. Manufactured to ANSI/ABMA 8.2 standards for dimensional accuracy and performance requirements, it ensures compatibility with 1.173"-18 screw sizes and chamfered bearing nuts. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial applications requiring restricted substance compliance.
