S-5909K49 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 ID tolerance (0" to 0.01") ensuring secure, vibration-resistant mounting in demanding applications.
• Robust steel construction delivers exceptional durability and load distribution, extending equipment service life under mechanical stress.
• Optimized outer diameter of 1 9/16" provides a broad bearing surface to prevent fastener embedment and surface damage.
• Consistent 0.032" thickness with controlled tolerance (-0.002" to 0") guarantees uniform clamping force and reliable assembly repeatability.
• Full RoHS 3 & REACH compliance ensures environmental safety and material traceability for global supply chain integration.
• Inch-system standardization simplifies sourcing and replacement in North American and international industrial maintenance operations.
• Heavy-duty ready design supports high-tolerance mechanical systems, reducing downtime and maintenance costs.

Professional Applications & Engineering Value

This precision steel washer is engineered to address critical alignment and stress distribution challenges in 1" shaft applications. The controlled inner diameter tolerance (0" to 0.01") eliminates play and minimizes fretting corrosion, while the 1 9/16" outer diameter effectively disperses load to protect softer mating surfaces. Manufactured from high-strength steel, it withstands repeated torque cycles and mechanical vibrations in industrial machinery, automotive assemblies, and heavy equipment. The 0.032" thickness ensures consistent spacing without compromising stack height, making it ideal for high-tolerance bolted connections where precision is non-negotiable. Its RoHS 3 and REACH compliance further guarantees that it meets stringent environmental regulations without sacrificing performance.

Specification Summary & Compliance

This washer conforms to inch-system dimensional standards with an ID of 1.002" (tolerance: 0" to +0.01"), OD of 1 9/16" (tolerance: -0.03" to -0.01"), and thickness of 0.032" (tolerance: -0.002" to 0"). It is designed specifically for 1" shaft diameters and is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
