Yuanping Xingsheng Machinery Manufacturing Co., Ltd. is proud to operate a cutting-edge TKAS idler production line, expertly designed by the illustrious Tangshan Kaiyuan. This is further enhanced by three semi-automatic production lines from this acclaimed manufacturer, ensuring precision and efficiency. Furthermore, we boast two advanced idler shaft material production lines from Fuzhou Sanxun, equipping us to adeptly manage a wide range of idler diameters starting fromφ89 mm to φ219 mm, delivering an extraordinary length range from 190 mm to 2200 mm.Our unwavering dedication to quality is embodied in our choice of high-grade special steels for idlers. We meticulously source these premium materials from esteemed suppliers like Xuzhou Guanghuan and Taiyuan Iron and Steel (TISCO) stainless steel pipes, guaranteeing unparalleled quality and performance.
Our relentless pursuit of superior quality is evident in our specialized steel pipe straightening process, dramatically reducing ovality and straightness deviations of roller rings by an astounding 50% against the MT821 standard. The idler’s simulated frictional resistance coefficient impressively decreases from 0.025 to 0.023, while radial runout is refined from 1.0 mm to an exceptional 0.35 mm. Post-straightening straightness is enhanced from 1.0 mm to a remarkable 0.20 mm. With an axial load exceeding 15 KN, conforming to the MT821 standard, our idlers achieve a higher precision grade with a service life surpassing a remarkable 45,000 hours.
Our production line stands as a testament to technological mastery, achieving complete automation across all phases, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless process exemplifies the zenith of efficiency and technological innovation.
In our idler shaft processing, we leverage state-of-the-art fully automated production lines, performing precise operations such as servo-fixed-length cutting, end face turning, chamfering, snap ring groove cutting, center hole drilling, and milling flat grooves on the idler shaft. The minimal distance between two milled grooves can be as short as 190mm,capable of processing workpieces up to a maximum length of 2200mm.
Technological level
1. Our idlers are ingeniously designed for effortless replacement, utilizing robust welding techniques that ensure the idler shell remains unworn throughout its remarkable service life, extending no less than 45,000 hours.
2. Incorporating specialized bearings and stamped bearing housings with dual-layer seals, our idlers guarantee exceptional sealing, minimal rotational resistance, and prolonged durability. We use premier bearings from esteemed brands like NSK for unmatched performance.
3. The external dustproof features of our idlers strictly adhere to MT821 - 1999 standards, ensuring unparalleled waterproof capabilities that fully comply with these rigorous criteria.
4. Each steel component undergoes thorough pre-treatment to reach the St2-1/2 level. Components with welded structures are manufactured following stringent national welding standards, ensuring structural compliance with the most recent national guidelines.
5. The rotational resistance coefficient of the upper idlers is precisely 0.022 or below, while the lower idlers maintain an even more commendable coefficient, not exceeding 0.02, underscoring our commitment to engineering excellence and superior performance.
