S-5909K64 1.127" ID x 1.75" OD Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Superior Load Distribution – High-strength steel construction provides excellent bearing surface support for 1-1/8" shafts, preventing component deformation under heavy loads
• Precision Fit Guarantee – Tight ID tolerance (0" to 0.01") ensures perfect shaft alignment while controlled OD tolerance (-0.03" to -0.01") maintains proper seating in assembly applications
• Enhanced Durability – Industrial-grade steel material offers exceptional resistance to wear, deformation, and mechanical stress in demanding environments
• Regulatory Compliance – Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards for safe use in global markets and sensitive applications
• Optimal Thickness Control – Consistent 0.126" thickness with minimal variation (-0.003" to 0") ensures uniform pressure distribution and reliable stack-up dimensions
• Inch System Compatibility – Designed specifically for imperial measurement systems, eliminating conversion errors in North American and international inch-based applications
• Reduced Maintenance Requirements – Robust steel construction minimizes replacement frequency, lowering total cost of ownership for industrial operations

Professional Applications & Engineering Value

This precision steel washer delivers critical engineering solutions for industrial applications requiring exact dimensional control. The 1.127" ID with tight tolerance specifications ensures perfect compatibility with 1-1/8" shaft diameters, eliminating play and misalignment issues common in rotating equipment and mechanical assemblies. The industrial-grade steel material provides superior load-bearing capacity, distributing forces evenly across the 1.75" OD contact surface to prevent brinelling and surface damage. Engineering teams specify this high-tolerance washer for heavy machinery, agricultural equipment, and industrial motors where precise dimensional control directly impacts operational reliability and service life. The combination of inch system compatibility and rigorous manufacturing standards makes this component ideal for replacement parts and OEM applications across multiple industrial sectors.
