Yuanping Xingsheng Machinery Manufacturing Co., Ltd. takes pride in deploying a cutting-edge TKAS idler production line, precisely architected by Tangshan Kaiyuan. Complemented by three semi-automatic production lines from the same esteemed manufacturer, we ensure remarkable precision and efficiency. Our capabilities are further enhanced by two advanced idler shaft material production lines from Fuzhou Sanxun, allowing us to manage an impressive array of idler diameters ranging fromφ89 mm to φ219 mm, and offering an exceptional length range from 190 mm to 2200 mm.Our unwavering dedication to quality is highlighted by our choice of superior special steels for idlers. We partner with trusted suppliers, such as Xuzhou Guanghuan and Taiyuan Iron and Steel (TISCO) stainless steel pipes, ensuring peerless quality and performance.
Our relentless pursuit of quality is exemplified by our specialized steel pipe straightening process, which significantly reduces ovality and straightness deviations of roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is remarkably lowered from 0.025 to 0.023, while radial runout is refined from 1.0 mm to an extraordinary 0.35 mm. Post-straightening straightness is enhanced from 1.0 mm to an impressive 0.20 mm. With our idlers bearing an axial load exceeding 15 KN, as per the MT821 standard, they achieve a superior precision grade with a service life surpassing an astonishing 45,000 hours.
Our production line shines as a beacon of technological excellence, achieving full automation across every stage, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless operation epitomizes ultimate efficiency and cutting-edge innovation.
Our idler shaft processing employs advanced fully automated production lines, carrying out meticulous operations like servo-fixed-length cutting, end face turning, chamfering, snap ring groove cutting, center hole drilling, and milling flat grooves on the idler shaft. The distance between two milled grooves can be as minimal as 190mm,with the capacity to handle workpieces up to a maximum length of 2200mm.
Technological level
1. Our idlers are ingeniously designed for easy replacement, employing robust welding technology that ensures the idler shell remains unworn throughout its remarkable service life of no less than 45,000 hours.
2. Equipped with specialized bearings and stamped bearing housings with double-layer seals, our idlers offer superior sealing, minimal rotational resistance, and prolonged durability. We use premium bearings from celebrated brands such as NSK for unmatched performance.
3. The external dustproof capabilities of our idlers are meticulously aligned with the MT821 - 1999 regulations, guaranteeing exceptional waterproof performance that fully adheres to these stringent standards.
4. Each steel material undergoes rigorous pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are crafted in strict compliance with national welding standards, ensuring structural alignment with the latest national criteria.
5. The rotational resistance coefficient of the upper idlers is precisely 0.022 or below, while the lower idlers sustain an even more impressive coefficient of no more than 0.02, emphasizing our commitment to superior engineering and performance.
