[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally recognized OE specialist in wiper transmission systems, is pleased to spotlight its high-performance Bus Auto Wiper Linkage (Model: CAP723004). Belonging to the "To Shave" wiper linkage category — characterized by its parallel opposing sweep motion — this dual-output shaft assembly is purpose-engineered for trucks, commercial coaches, and specialized heavy vehicles requiring precise, synchronized dual-arm windshield clearing.
Dual Output Shaft Design: Synchronized Motion for Commercial Safety The CAP723004 is built around a two-output shaft configuration with M8 threaded output shafts and a robust M20 tube sleeve installation, delivering a mechanically stable foundation that drives both wiper arms in perfect synchronization. The "to shave" mechanism produces a mirrored sweep pattern that is particularly effective on wide, flat commercial windshields, ensuring the maximum possible glass area is cleared with every cycle. For long-haul coaches navigating heavy rainfall or sleet, this synchronized precision is a direct contributor to driver safety.
EU & US Compliant Zinc Coating: 200-Hour Salt Spray Tested Surface corrosion is one of the primary failure modes for wiper linkage components. The CAP723004 addresses this with a zinc-coated surface featuring blue-white passivation and color passivation treatment, completely free of high-valence chromium ions. This coating is fully compliant with the environmental protection requirements of the European Union and the United States (RoHS), and has been validated to withstand over 200 hours of continuous salt spray testing. This ensures long-term structural integrity even in coastal routes, winter road-salt environments, and tropical humid conditions.
Low-Noise, Long-Life Mechanism Smooth, quiet operation is not a luxury — it is a professional standard. The CAP723004 is engineered with precision-fitted pivot joints and optimized linkage geometry to minimize friction and mechanical play throughout its full sweep range. The result is an assembly that operates with low noise and reduced vibration, extending the service life of both the linkage and the wiper motor it is paired with. With a supply capacity of 50,000 units per cycle, ISO9001 certification, and flexible FOB/CIF shipping from Ningbo and Shanghai, CAP is the dependable global partner for bus manufacturers and commercial vehicle fleet operators worldwide.
