Professional Applications & Engineering Value

This M85 spring lock washer delivers exceptional engineering value in applications where vibration-induced loosening poses significant operational risks. The conical shape with external teeth creates multiple biting points that securely lock bearing nuts in position, maintaining clamping force even under extreme vibration conditions. Manufactured from high-quality steel, this washer provides reliable performance in heavy machinery, automotive assemblies, and industrial equipment where bearing retention is critical. The chamfered face style ensures smooth installation while optimizing contact with bearing surfaces. Meeting DIN 5406 specifications, this component offers predictable performance and interchangeability across European-engineered systems, reducing maintenance frequency and improving operational safety in vibration-prone environments.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions including 85mm internal diameter, 119mm outer diameter, and 1.750mm thickness with 5.5mm overall height. Manufactured in compliance with DIN 5406 for spring lock washers and DIN 981 for bearing nut applications. The product maintains RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements, ensuring environmental responsibility and regulatory acceptance for industrial use across global markets.
