Professional Applications & Engineering Value
This precision steel washer is engineered to solve critical challenges in industrial assembly and machinery maintenance. The 0.877" ID and 1 7/16" OD dimensions with controlled tolerances prevent shaft play and bearing surface wear in 7/8" shaft applications, making it ideal for automotive, conveyor systems, and heavy equipment. The steel construction withstands vibration and load stresses that cause premature failure in inferior washers. Combined with RoHS and REACH compliance, this washer meets both technical and regulatory demands for manufacturers operating in global supply chains, ensuring both mechanical reliability and environmental responsibility.
Specification Summary & Compliance
Manufactured to precise inch system tolerances (ID: 0" to +0.01", OD: -0.03" to -0.01", Thickness: -0.003" to 0") for consistent performance. Constructed from industrial-grade steel with a standard thickness of 0.126". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
