S-5909K67 1.502" ID x 2 3/16" OD Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Precision Fit for 1 1/2" Shafts: Tight inner diameter tolerance (0" to +0.01") ensures secure seating and reduced vibration in demanding mechanical assemblies.
• Enhanced Load Distribution: Generous 2 3/16" outer diameter provides a larger bearing surface, effectively distributing pressure and preventing surface damage.
• Robust Steel Construction: Manufactured from durable steel for high strength, excellent wear resistance, and long-term reliability in industrial environments.
• Consistent Dimensional Stability: Controlled thickness (0.126" with -0.003" to 0" tolerance) guarantees uniform performance and predictable assembly stack-up.
• Global Environmental Compliance: Meets RoHS 3 and REACH standards, ensuring safety for restricted substances and enabling use in regulated markets.
• Optimized for Inch-System Applications: Designed to imperial specifications, providing a perfect fit for machinery and equipment using inch-based components.
• Reliable in Heavy-Duty Use: The combination of precise tolerances and sturdy steel material makes it ideal for high-stress, mechanical, and shaft applications.

Professional Applications & Engineering Value

This precision steel washer is engineered to address common challenges in industrial assemblies, such as component misalignment, bolt loosening, and surface indentation. Its 1.502" ID with minimal positive tolerance ensures a snug fit on 1 1/2" shafts, minimizing play and enhancing rotational stability. The large 2 3/16" OD effectively spreads clamp load over a wider area, protecting softer materials and reducing stress concentration. Made from high-strength steel, it withstands heavy loads and repetitive forces in machinery, automotive, and construction equipment. The tight thickness tolerance ensures consistent performance in stacked assemblies, preventing gaps and maintaining torque integrity. Ideal for precision washers requirements, it delivers reliability in high-vibration environments, ensuring long-term operational safety and reducing maintenance needs.

Specification Summary & Compliance

This washer adheres to inch system measurements with precise dimensional tolerances: Inner Diameter (ID) of 1.502" (0" to +0.01"), Outer Diameter (OD) of 2 3/16" (-0.03" to -0.01"), and Thickness of 0.126" (-0.003" to 0"). It is manufactured to standard industrial specifications for flat washers and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting global supply chain requirements.
