S-5909K89 30.04 mm ID x 47 mm OD Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Precise 30mm shaft compatibility with 30.04mm ID ensures perfect fit and eliminates wobbling in mechanical assemblies
• Superior load distribution thanks to 47mm outer diameter that protects mating surfaces from deformation under heavy loads
• Consistent thickness control at 3.0mm maintains uniform clamping force and prevents joint loosening in vibrating environments
• High-strength steel construction delivers exceptional durability and corrosion resistance for long service life in demanding applications
• Tight tolerance manufacturing guarantees dimensional accuracy and interchangeability across production batches
• Environmental compliance assurance with RoHS 3 and REACH adherence meets global regulatory standards for industrial components
• Optimized for industrial machinery where reliable shaft mounting and vibration resistance are critical to operational safety

Professional Applications & Engineering Value

This precision metric steel washer solves critical engineering challenges in industrial machinery and mechanical systems where shaft-mounted components require secure fastening. The 30.04mm ID provides optimal clearance for 30mm shafts while maintaining sufficient contact area to prevent stress concentration. The 47mm OD creates an expanded bearing surface that distributes clamping forces evenly, protecting delicate housing surfaces from indentation and deformation. Manufactured from high-grade steel, this heavy-duty washer withstands extreme mechanical stresses and environmental exposure, making it ideal for power transmission systems, rotating equipment, and industrial automation applications where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This metric precision washer maintains exacting dimensional standards with ID tolerance (0mm to +0.21mm), OD tolerance (-0.57mm to -0.32mm), and thickness tolerance (-0.06mm to 0mm) ensuring consistent performance in Class 2A equivalent applications. The component is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial markets and environmentally conscious manufacturing operations.
