• Consistent performance guaranteed by tight dimensional tolerances across ID, OD, and thickness for reliable assembly and interchangeability
• Exceptional durability provided by steel construction, offering high strength and resistance to wear in industrial environments
• Environmental compliance assurance with full RoHS 3 and REACH adherence, meeting strict material safety standards for global industrial use
• Optimized for industrial hardware with inch system measurements, ensuring compatibility with standard machinery and equipment components

Professional Applications & Engineering Value

This precision steel washer addresses critical engineering challenges in heavy-duty industrial applications where shaft alignment and load distribution are paramount. The precisely controlled 1.252" ID creates an exact interface with 1 1/4" shaft diameters, eliminating play that can lead to equipment vibration, premature wear, and mechanical failure. The generous 1 15/16" OD provides expanded bearing surface area, effectively distributing clamping forces and preventing surface deformation in high-stress assemblies. Manufactured from steel material, this washer maintains structural integrity under repeated loading cycles, making it ideal for machinery, automotive, and manufacturing equipment where precision tolerance washers are essential for maintaining operational reliability and reducing maintenance downtime.
