The Bushing Chain (Seamless Bushing ) is composed of four major parts: inner chain plate, outer chain plate, pin shaft, and sleeve. Qingdao Zhenghe uses imported raw materials and processing equipment, uses chrome infiltration and isothermal treatment processes, and obtains products with high fatigue and wear resistance through precise chain assembly and automatic strengthening pre tensioning. The product uses seamless sleeves formed through cold extrusion technology, which have no gaps and are not easily deformed. The seamless sleeves are in contact with the pin shaft on a surface, improving the wear resistance of the product.
