Professional Applications & Engineering Value

This precision steel washer is engineered to solve critical alignment and load distribution challenges in industrial machinery and equipment. The precisely controlled 2.252" ID ensures secure seating on 2-1/4" shafts, eliminating play and reducing stress concentrations that can lead to premature failure. The 3" OD provides optimal surface contact for even pressure distribution, protecting mating surfaces from deformation. Manufactured from high-quality steel material, this washer maintains structural integrity under heavy loads and repetitive stress cycles. The tight tolerance control across all dimensions makes it ideal for precision assemblies in automotive, manufacturing, and heavy equipment applications where dimensional accuracy directly impacts operational reliability and maintenance intervals.

Specification Summary & Compliance

This precision steel washer features exact dimensional specifications: 2.252" ID (0" to +0.01" tolerance), 3" OD (-0.03" to -0.01" tolerance), and 0.032" thickness (-0.002" to 0" tolerance). Designed specifically for 2-1/4" shaft diameter applications, the washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial use across global markets.
