At Yuanping Xingsheng Machinery Manufacturing Co., Ltd., we proudly operate a cutting-edge TKAS idler production line, masterfully crafted by Tangshan Kaiyuan. This advanced setup is further enhanced by three semi-automatic production lines from the same esteemed manufacturer, ensuring unmatched precision and operational efficiency. Moreover, our facility includes two state-of-the-art idler shaft material production lines from Fuzhou Sanxun, empowering us to proficiently manage a wide spectrum of idler diameters ranging fromφ89 mm to φ219 mm, and providing an extraordinary length range from 190 mm to 2200 mm.Our unwavering dedication to excellence is evident in our selection of premium special steels for idlers. We procure these superior materials from distinguished suppliers such as Xuzhou Guanghuan and Taiyuan Iron and Steel (TISCO) stainless steel pipes, ensuring that our products deliver peerless quality and performance.
Our relentless pursuit of superior quality is reflected in our sophisticated steel pipe straightening process, which remarkably reduces ovality and straightness variations of roller rings by an astounding 50% when compared to the MT821 standard. The idler's simulated frictional resistance coefficient is impressively lowered from 0.025 to 0.023, with radial runout optimized from 1.0 mm to an exceptional 0.35 mm. Post-straightening, the straightness is enhanced from 1.0 mm to an extraordinary 0.20 mm. Withstanding an axial load exceeding 15 KN, in accordance with the MT821 standard, our idlers achieve a remarkable precision grade with a service life surpassing an exceptional 45,000 hours.
Our production line exemplifies technological sophistication, achieving full automation across all stages including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless process represents the pinnacle of efficiency and innovation, ensuring the highest quality in each product.
Our idler shaft processing utilizes state-of-the-art fully automated production lines, precisely conducting 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 distance between two milled grooves can be as minimal as 190mm,and capable of accommodating workpieces up to a maximum length of 2200mm.
Technological level
1. Our idlers are skillfully engineered for effortless replacement, utilizing advanced welding techniques that ensure the idler shell remains unblemished throughout its robust service life of no less than 45,000 hours.
2. Featuring precision-engineered bearings and stamped bearing housings with dual-layer seals, our idlers deliver exceptional sealing, minimal rotational resistance, and prolonged durability. We employ premier bearings from esteemed brands such as NSK to guarantee superior performance.
3. The advanced dustproof capabilities of our idlers meticulously adhere to the MT821 - 1999 regulations, ensuring exemplary waterproof performance that meets these rigorous standards.
4. Each steel material undergoes comprehensive pre-treatment to meet the St2-1/2 level. Components involving welded structures are manufactured in strict conformance with national welding standards, ensuring structural integrity and alignment with the latest national criteria.
5. The upper idlers' rotational resistance coefficient is precisely maintained at 0.022 or below, while the lower idlers boast an even more remarkable coefficient, not surpassing 0.02, highlighting our commitment to exceptional engineering and performance.
