Tagging of couplings serves as a fundamental and standardized management procedure in modern mechanical operation and industrial maintenance, playing an irreplaceable role in ensuring equipment safety and operational consistency. As core connecting components for mechanical transmission systems, couplings undertake torque transmission and shaft connection tasks, and their accurate tagging effectively records key attribute information including component specifications, performance parameters and service status. This systematic marking method eliminates confusion caused by similar structural appearances of different couplings, facilitating precise identification during equipment inspection, routine maintenance and component replacement. In addition, standardized coupling tagging supports full lifecycle management of mechanical parts, helps track operating fatigue and service duration, and assists technical staff in judging component aging and wear conditions. It greatly improves the efficiency of industrial equipment management, reduces operational risks caused by mismatched or overdue parts, and maintains the long-term stable and safe operation of various mechanical transmission systems in diverse industrial scenarios.
