S-5909K63 1.002" ID x 1 9/16" OD Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Precision fit for 1" shafts with tight inner diameter tolerance (0" to 0.01") to reduce vibration and ensure secure assembly.
• Durable steel construction provides excellent load distribution and resistance to wear in demanding industrial environments.
• Optimized dimensions (1.002" ID, 1 9/16" OD, 0.126" thickness) offer a larger bearing surface to prevent fastener embedment and joint failure.
• Strict dimensional control on OD (-0.03" to -0.01") and thickness (-0.003" to 0") ensures consistent performance and interchangeability.
• Full RoHS 3 & REACH compliance guarantees environmental safety and material reliability for global supply chain integration.
• Ideal for heavy-duty applications where precise shaft alignment and long-term mechanical integrity are critical.
• Manufactured to inch system standards for seamless compatibility with North American machinery and equipment.

Professional Applications & Engineering Value

This precision steel washer is engineered to solve common industrial challenges such as shaft misalignment, bearing surface wear, and bolt loosening under dynamic loads. Its 1.002" inner diameter with minimal tolerance ensures a perfect fit on standard 1" shafts, eliminating play and reducing maintenance frequency. The robust steel material and controlled OD of 1 9/16" provide a reliable barrier against corrosion and deformation, making it suitable for heavy machinery, conveyor systems, and power transmission assemblies. By maintaining tight dimensional accuracy, this washer enhances the lifespan of connected components and supports efficient industrial operations with minimal downtime.

Specification Summary & Compliance
