[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally recognized OE specialist in wiper system engineering, is pleased to spotlight its Wiper Linkage Crank Assembly (Model: CAP104293). As the critical mechanical bridge between the wiper motor and the linkage rod mechanism, this precision crank assembly plays a foundational role in converting motor rotation into the synchronized sweeping motion that keeps windshields clear and drivers safe.
Precision Geometry for Smooth, Reliable Motion The CAP104293 features a precisely calibrated 57.5mm center distance, engineered to deliver optimal leverage and consistent stroke timing across the full range of wiper motion. The 60 straight-teeth motor connection ensures a firm, zero-slip engagement with the motor output shaft, eliminating the vibration and backlash that lead to premature wear in the entire linkage assembly. The Φ12mm shaft diameter and Φ12.7mm tip are machined to tight tolerances, guaranteeing accurate, repeatable motion cycle after cycle.
European-Standard Corrosion Protection: 500+ Hours Salt Spray Tested Operating conditions for commercial vehicle wiper linkages are among the most demanding in the automotive world — constant exposure to rain, road salt, and humidity. The CAP104293 addresses this directly with a specialized electroplating surface treatment that is completely free of high-priced chromium ions, fully compliant with European environmental standards (RoHS). This treatment has been validated to withstand over 500 hours of continuous salt spray testing, ensuring long-term structural integrity even in the harshest coastal or winter road environments.
ISO9001-Certified Reliability for the Global Aftermarket Every CAP104293 is manufactured under CAP's ISO9001-certified quality management system, ensuring consistent dimensional accuracy and surface quality across every production batch. With a monthly supply capacity of up to 50,000 units and flexible shipping from Ningbo and Shanghai ports, CAP is fully equipped to meet the demands of global distributors, OEMs, and the automotive maintenance market. Its neutral packaging and standard FOB/CIF terms make it a seamless sourcing choice for international buyers.
