[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally recognized OE specialist in wiper system engineering, is pleased to spotlight its One-Way Scraping Wiper Linkage Assembly (Model: CAP722018). Engineered for the expansive windshields of large and medium-sized passenger coaches and special-purpose vehicles, this high-precision linkage assembly provides the structural backbone that converts wiper motor power into smooth, synchronized dual-arm sweeping motion.
Dual Output Shaft Design for Full Windshield Coverage The CAP722018 features a purpose-built dual output shaft configuration, driving two independent wiper arms simultaneously from a single actuator assembly. This design is essential for the wide panoramic windshields of modern intercity buses and coaches, where a single-arm system would leave critical blind zones uncleared. With a precisely calibrated 1833mm installation center distance and an M26 threaded tube sleeve paired with an M10 output shaft, the assembly delivers exact, repeatable motion geometry across millions of cycles.
European-Compliant Eco-Friendly Electroplating Surface Operating components exposed to road salt, moisture, and UV require surface protection that goes beyond standard galvanization. The CAP722018 is finished with a specialized electroplating layer that contains zero high-valence chromium ions, fully conforming to European environmental (RoHS) standards. This environmentally responsible coating not only protects the steel structure from corrosion but also ensures the product meets the compliance requirements of export markets across the EU. Upon customer request, the surface treatment can also be customized to standard environmental-grade galvanization.
Precision Ball-Bearing Hinge for Silent, Long-Life Operation At the heart of every reliable wiper linkage is its hinge mechanism. The CAP722018 uses a shaft-and-ball-bearing joint design at each pivot point, drastically reducing friction and mechanical wear compared to conventional bush-type hinges. The result is a smoother, quieter wiping action that reduces driver fatigue during long routes and simultaneously extends the operational lifespan of both the linkage and the wiper motor. Manufactured under strict ISO9001 quality management in Hangzhou, China, with a supply capacity of up to 500,000 units, CAP is fully equipped to serve major coach manufacturers and global distributors worldwide
