Professional Applications & Engineering Value

This precision steel washer is engineered to solve critical challenges in 45mm shaft applications where improper load distribution can lead to premature failure. The carefully calculated 45.05mm inner diameter with controlled tolerance provides optimal clearance for smooth installation while maintaining secure positioning. The 65mm outer diameter significantly increases the bearing surface area, effectively distributing clamping forces and preventing stress concentration that could damage mating surfaces. Manufactured from high-grade steel, this metric washer offers exceptional resistance to deformation under heavy loads, making it ideal for industrial machinery, automotive assemblies, and heavy equipment where vibration resistance and long-term reliability are paramount. The precise 4.0mm thickness ensures consistent performance in bolted connections, maintaining proper preload and preventing joint loosening in dynamic applications.

Specification Summary & Compliance

This precision metric washer features exacting dimensional specifications: ID 45.05mm (tolerance 0mm to +0.25mm), OD 65mm (tolerance -0.64mm to -0.34mm), and thickness 4.0mm (tolerance -0.075mm to 0mm). The manufacturing process adheres to strict quality standards ensuring consistent performance in industrial applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components. Designed specifically for 45mm shaft diameters, this washer delivers reliable performance in mechanical systems requiring precise dimensional control and regulatory compliance.
