Our esteemed company is proud to feature a state-of-the-art TKAS idler production line designed by the illustrious Tangshan Kaiyuan. This is further augmented by three additional semi-automatic idler production lines, also crafted by this renowned manufacturer. In addition, we boast two advanced idler shaft material production lines, developed by the distinguished Fuzhou Sanxun. Together, these facilities empower us with the formidable capacity to process a diverse array of idlers with diameters that range impressively fromφ89 mm-φ219mm and exhibit a substantial length range extending from 190mm - 2200mm. At the heart of our commitment to excellence is our use of high-quality special steels for idlers, meticulously sourced from esteemed suppliers like Xuzhou Guanghuan and the prestigious Taiyuan Iron and Steel (TISCO) stainless steel pipes.

Our unwavering commitment to superior quality is evident in our specialized straightening process for steel pipes. This meticulous procedure significantly diminishes the ovality and straightness errors of roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient has been expertly reduced from 0.025 to 0.023; radial runout has seen major enhancement from 1.0 mm to an outstanding 0.35 mm; and the post-straightening straightness is impressively improved from 1.0 mm to a remarkable 0.20 mm. With an axial load surpassing 15 KN, as defined by the MT821 standard, the lifespan of our idlers is elevated by one precision grade, exceeding an extraordinary 45,000 hours.

Our production line is a technological marvel, achieving full automation at every juncture of the idler production process. From straightening to pipe cutting, boring, stamping, welding, and assembly, every step is a testament to efficiency and innovation, ensuring top-notch quality and precision.

In our idler shaft processing, we utilize pioneering fully automatic production lines that execute 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. Remarkably, the distance between two milled grooves can be as minimal as 190mm, with the capability to process workpieces up to a considerable maximum length of 2200mm.

Technological level

1. Our idlers are ingeniously designed to be easily replaceable, with robust and enduring welding craftsmanship that ensures no wear on the idler shell throughout its impressive service life, which lasts no less than 45,000 hours.
2. Our idlers feature specialized bearings and stamped bearing housings with double-layer seals. This sophisticated design ensures exceptional sealing, minimal rotational resistance, and prolonged longevity. We meticulously select elite bearings from renowned brands like SKF to maximize performance.
3. The dustproof features of our idlers comply rigorously with the MT821 - 1999 regulations, and their waterproof performance meets these stringent standards with equal precision.
4. Every steel material undergoes extensive pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are manufactured with strict adherence to national welding standards, ensuring their structural integrity aligns with the latest national criteria.
5. The rotational resistance coefficient of the upper idlers is precisely maintained at 0.022 or lower, while the lower idlers achieve an even lower coefficient, not exceeding 0.02, highlighting our dedication to superior engineering and performance.
