Our esteemed company, Yuanping Xingsheng Machinery Manufacturing Co., Ltd., proudly showcases a state-of-the-art TKAS idler production line crafted by the acclaimed Tangshan Kaiyuan. This is further enhanced by three additional semi-automatic idler production lines from the same esteemed manufacturer. Additionally, we possess two cutting-edge idler shaft material production lines developed by the illustrious Fuzhou Sanxun. Our robust capabilities allow us to process a vast array of idlers, accommodating diameters fromφ89 mm-φ219mm and offering an impressive length range from 190mm - 2200mm. Our unyielding commitment to excellence is demonstrated by our utilization of premium special steels for idlers, sourced from prestigious suppliers like Xuzhou Guanghuan and the renowned Taiyuan Iron and Steel (TISCO) stainless steel pipes.
Our dedication to top-tier quality is unwavering as we carry out specialized straightening for steel pipes. This meticulous process reduces the ovality and straightness errors of roller rings by 50% compared to the MT821 standard. Notably, the idler's simulated frictional resistance coefficient has been remarkably decreased from 0.025 to 0.023. Radial runout has improved from 1.0 mm to a stunning 0.35 mm, and post-straightening straightness is enhanced from 1.0 mm to an extraordinary 0.20 mm. With an axial load exceeding 15 KN, as stipulated by the MT821 standard, the lifespan of our idlers is elevated by one precision grade, surpassing an impressive 45,000 hours.
Our production line is a marvel of technological sophistication, achieving full automation in every step of the idler production process. This includes straightening, pipe cutting, boring, stamping, welding, and assembly, epitomizing efficiency and innovation at every juncture.
Our idler shaft processing is executed on cutting-edge fully automated production lines, which perform precise servo-fixed-length cutting, end face turning, chamfering, snap ring groove cutting, center hole drilling, and milling flat groove operations on the idler shaft. Notably, the distance between two milled grooves can be as minimal as 190mm, with the capacity to handle workpieces up to a substantial maximum length of 2200mm
Technological level
1, Our idlers are ingeniously crafted for swift replacement, with welding craftsmanship that is robust and durable, ensuring no wear on the idler shell throughout its standard service life of at least 45,000 hours.
2, Our idlers feature specialized bearings and stamped bearing housings with double-layer seals, ensuring exceptional sealing, minimal rotational resistance, and extended longevity. We utilize elite bearings from reputable brands like SKF to guarantee optimum performance.
3, The dustproof capabilities of our idlers adhere strictly to the MT821 - 1999 regulations, and their waterproof performance is equally compliant with these stringent standards.
4, Every piece of steel material undergoes rigorous pre-treatment to achieve the St2-1/2 level. For welded structures, parts are manufactured in strict adherence to national welding standards, ensuring structural conformity with the latest national criteria.
5, The rotational resistance coefficient of the upper idlers is meticulously maintained at 0.022 or below, while the lower idlers boast an even lower coefficient, not exceeding 0.02, reflecting our commitment to superior engineering and performance.
