Yuanping Xingsheng Machinery Manufacturing Co., Ltd. takes pride in its cutting-edge TKAS idler production line, a masterpiece of design by the acclaimed Tangshan Kaiyuan. This is further enhanced by three semi-automatic production lines from the same esteemed producer, guaranteeing precision and efficiency. Additionally, we have two sophisticated idler shaft material production lines from Fuzhou Sanxun, enabling us to expertly manage a wide range of idler diameters.from φ89 mm to φ219 mm, offering an impressive length range from 190 mm to 2200 mm.Our unwavering commitment to quality shines through our selection of premium special steels for idlers. We source these top-notch materials from trusted suppliers, including Xuzhou Guanghuan and Taiyuan Iron and Steel (TISCO) stainless steel pipes, ensuring unmatched quality and performance.
Our quest for superior quality is evident in our specialized steel pipe straightening process, which significantly reduces ovality and straightness variances of roller rings by a remarkable 50% relative to the MT821 standard. The idler's simulated frictional resistance coefficient is impressively decreased from 0.025 to 0.023, while radial runout is refined from 1.0 mm to an astonishing 0.35 mm. Post-straightening straightness is enhanced from 1.0 mm to an outstanding 0.20 mm. With an axial load exceeding 15 KN, conforming to the MT821 standard, our idlers achieve an elevated precision grade with a service life extending beyond an extraordinary 45,000 hours.
Our production line stands as a testament to technological excellence, achieving complete automation across all phases, including straightening, pipe cutting, boring, stamping, welding, and assembly. This flawless process epitomizes the pinnacle of efficiency and innovation.
Our idler shaft processing utilizes state-of-the-art fully automated production lines, executing precise 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 spacing between two milled grooves can be as minimal as 190mm,capable of handling workpieces up to a maximum length of 2200mm.
Technological level
1. Our idlers are ingeniously crafted for effortless replacement, utilizing robust welding techniques that guarantee the idler shell remains unworn throughout its impressive service life of no less than 45,000 hours.
2. Featuring specialized bearings and stamped bearing housings with double-layer seals, our idlers offer outstanding sealing, minimal rotational resistance, and extended longevity. We incorporate top-tier bearings from esteemed brands such as NSK for unbeatable performance.
3. The external dustproof capabilities of our idlers rigorously adhere to the MT821 - 1999 regulations, ensuring superior waterproof performance that fully complies with these stringent standards.
4. Every steel material undergoes an exhaustive pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are crafted in strict accordance 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 maintain an even more impressive coefficient, not exceeding 0.02, highlighting our commitment to superior engineering and performance.
