S-5909K73 15.032 mm ID x 28 mm OD DIN 5405-3, ISO 303 Washers for Needle-Roller Thrust Bearings

Key Features & Benefits at a Glance

• Precise shaft fitment with 15.032mm ID and controlled tolerances ensures secure positioning and reduced vibration in 15mm shaft assemblies
• Enhanced load distribution through 28mm OD design minimizes surface pressure and prevents component deformation
• Consistent performance guaranteed by 1mm thickness with tight ±0.05mm tolerance for uniform spacing in stacked applications
• Industry-standard compatibility with DIN 5405-3 and ISO 303 specifications ensures reliable interchangeability across European mechanical systems
• Long-term durability from high-quality steel construction withstands industrial wear and repeated assembly cycles
• Environmental compliance with RoHS 3 and REACH regulations makes this washer suitable for global supply chains and sensitive applications
• Reduced maintenance needs through precision manufacturing decreases wear on both washer and mating components

Professional Applications & Engineering Value

This metric steel washer delivers critical engineering solutions for precision shaft applications where exact tolerances determine system reliability. Manufactured to DIN 5405-3 and ISO 303 standards, the precisely controlled 15.032mm internal diameter with minimal tolerance variation ensures perfect alignment on 15mm shafts, eliminating play that causes premature wear in rotating equipment. The 28mm outer diameter provides optimal bearing surface distribution, while the 1mm thickness maintains consistent spacing in multi-washer configurations. These precision washers are particularly valuable in industrial machinery, automotive assemblies, and precision instruments where vibration resistance and dimensional stability are paramount. The steel construction offers excellent strength-to-weight ratio for heavy-duty applications without adding unnecessary bulk to the assembly.

Specification Summary & Compliance

This precision shaft washer features dimensional specifications including 15.032mm ID (0mm to +0.18mm tolerance), 28mm OD (-0.212mm to -0.032mm tolerance), and 1mm thickness (±0.05mm tolerance) designed specifically for 15mm shaft applications. The product conforms to DIN 5405-3 and ISO 303 international standards for dimensional accuracy and performance requirements. Environmental compliance is verified through RoHS 3 (2015/863/EU) certification and REACH (EC 1907/2006) adherence, ensuring suitability for regulated industrial markets and international procurement specifications.
