[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally trusted OE specialist in professional wiper transmission engineering, is proud to highlight its flagship solution for ultra-wide commercial vehicles: the High-Quality Dual-Scraper Wiper Linkage (Model: CAP722020). Currently exported to Europe and France, this heavy-duty two-scraper transmission assembly represents CAP's most robust linkage engineering, combining structural steel construction with precision joint bearing technology to deliver reliable, smooth wiper performance across the widest commercial vehicle windshields in demanding operational environments.
20×2 Steel Tube Links: Industrial-Grade Structural Backbone The defining engineering feature of the CAP722020 is its link rods constructed from 20×2mm steel tubes — a specification chosen specifically for ultra-wide heavy-duty vehicle applications where standard linkage rod dimensions would introduce unacceptable flex or vibration at full extension. The 20×2 steel tube profile delivers a superior strength-to-weight ratio, maintaining rigid, consistent geometry across the full linkage span even under the high mechanical loads generated by large, heavy wiper blades operating at highway speeds or in heavy precipitation.
Joint Bearing Hinges: Zero Slack, Precision Motion At every pivot point, the CAP722020 uses joint bearing (spherical plain bearing) hinges rather than conventional bush-type connections. This engineering choice delivers two critical advantages. First, joint bearings provide multi-axis articulation tolerance, compensating for minor installation misalignments without introducing mechanical stress into the linkage — essential for the complex mounting geometry of wide-body vehicle cab structures. Second, the precision-ground bearing surfaces eliminate the rotational slack and hysteresis that cause wiper arms to drift from their intended sweep arc over time, ensuring that both scrapers maintain consistent, synchronized sweeping throughout the product's service life.
Chromium-Free EU/US Compliant Electroplating: Built for Export Markets The CAP722020 features a specialized electroplating surface treatment that contains zero high-valence chromium ions, fully meeting the chemical substance restriction requirements of both the European Union and the United States. This compliance-grade surface protection is not merely a regulatory checkbox — it provides genuine long-term corrosion resistance against the road salt, industrial moisture, and UV degradation that heavy vehicle linkages encounter daily. The product's active export status to France and Europe validates this compliance at the highest commercial level, giving international procurement teams confidence in specification approval.
OE-Grade Quality, Global Heavy Vehicle Supply Manufactured in Hangzhou, China under strict ISO9001-certified quality management, the CAP722020 is available with a supply capacity of up to 500,000 units per cycle. With FOB shipping from Ningbo and Shanghai ports under flexible L/C or T/T payment terms, CAP serves the full spectrum of global heavy vehicle customers — from OEM integrators requiring consistent batch quality to international aftermarket distributors supplying fleet maintenance programs for mining, construction, and long-haul freight operations.
