Professional Applications & Engineering Value

This precision steel washer is engineered to solve critical alignment and load-bearing challenges in industrial machinery. Its 2.25" ID is specifically designed for 2 1/4" shaft diameters, providing a secure interface that prevents axial movement and distributes clamping force evenly. The tight tolerance control on both ID and OD dimensions ensures consistent performance in automated assembly lines, eliminating the need for manual adjustments. Made from high-grade steel, this industrial washer withstands substantial mechanical stress in applications ranging from power transmission systems to heavy equipment manufacturing. The inch measurement system makes it particularly valuable for maintaining legacy equipment and North American industrial standards, while the precise 0.03125" thickness maintains optimal spacing in confined assembly environments.

Specification Summary & Compliance

This precision steel washer features exact dimensional specifications: 2.25" ID with 0.002" to 0.012" tolerance, 3" OD with -0.03" to -0.01" tolerance, and 0.03125" thickness with -0.00125" to 0.00075" tolerance. Manufactured to inch system standards for compatibility with North American industrial equipment. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety.
