At Yuanping Xingsheng Machinery Manufacturing Co., Ltd., we take pride in our state-of-the-art TKAS idler production line, expertly crafted by the renowned Tangshan Kaiyuan. This cutting-edge line is supported by three semi-automatic production lines from the same distinguished manufacturer, ensuring unmatched precision and efficiency. Additionally, our production capabilities are bolstered by two advanced idler shaft material lines from Fuzhou Sanxun, empowering us to proficiently manage a wide range of idler diameters, fromφ89 mm to φ219 mm, offering a remarkable length flexibility from 190 mm to 2200 mm.Our unwavering dedication to superior quality is reflected in our choice of premium-grade special steels for idlers. We source these materials from esteemed suppliers such as Xuzhou Guanghuan and Taiyuan Iron and Steel (TISCO) stainless steel pipes, ensuring unparalleled quality and performance that meets the highest standards.
Our relentless pursuit of quality excellence is evident in our specialized steel pipe straightening process, which significantly reduces ovality and straightness variability of roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is outstandingly decreased from 0.025 to an impressive 0.023, while radial runout is optimized from 1.0 mm to an exceptional 0.35 mm. Post-straightening straightness is enhanced from 1.0 mm to an extraordinary 0.20 mm. With an axial load exceeding 15 KN as per the MT821 standard, our idlers achieve a superior precision grade with a remarkable service life surpassing 45,000 hours.
Our production line epitomizes technological excellence, achieving complete automation across every phase, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless process represents the ultimate in efficiency and innovative engineering.
Our idler shaft processing utilizes state-of-the-art fully automated production lines, executing precision 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 minimum distance between two milled grooves can be as small as 190mm,capable of managing workpieces up to an impressive maximum length of 2200mm.
Technological level
1. Our idlers are expertly designed for easy replacement, with robust welding techniques that ensure the idler shell remains unworn throughout its extensive service life, lasting no less than 45,000 hours.
2. Featuring specialized bearings and stamped bearing housings with dual-layer seals, our idlers guarantee superior sealing, minimal rotational resistance, and enhanced longevity. We employ top-quality bearings from esteemed brands such as NSK for unparalleled performance and reliability.
3. Our idlers' external dustproof features strictly adhere to the MT821 - 1999 regulations, ensuring outstanding waterproof capabilities that fully meet these rigorous standards.
4. Each steel material undergoes rigorous pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are manufactured 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 exceptional coefficient, not exceeding 0.02, highlighting our dedication to superior engineering and performance.
