Our relentless pursuit of quality is reflected in our specialized steel pipe straightening process, which drastically reduces ovality and straightness variations in roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is remarkably optimized from 0.025 to 0.023, while radial runout is improved from 1.0 mm to an extraordinary 0.35 mm. Post-straightening straightness enhances from 1.0 mm to a remarkable 0.20 mm. With an axial load exceeding 15 KN per the MT821 standard, our idlers achieve a superior precision grade with a service life surpassing an exceptional 45,000 hours.
Our production line is a testament to technological excellence, achieving full automation across all processes, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless operation embodies the epitome of efficiency and innovation.
Our idler shaft processing leverages state-of-the-art fully automated production lines, carrying out precise tasks 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 distance between two milled grooves can be as minimal as 190mm,capable of accommodating workpieces up to a maximum length of 2200mm.



1. Our idlers are expertly designed for effortless replacement, with advanced welding techniques ensuring the idler shell remains wear-free throughout its impressive service life, which extends beyond 45,000 hours.
2. Featuring specialized bearings and stamped bearing housings with dual-layer seals, our idlers deliver exceptional sealing, minimal rotational resistance, and extended longevity. We incorporate top-of-the-line bearings from renowned brands like SKF for unmatched performance.
3. The external dustproof capabilities of our idlers are rigorously aligned with the MT821 - 1999 regulations, ensuring exceptional waterproof performance in full compliance with these stringent standards.
4. Each steel material undergoes thorough pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are manufactured in strict compliance 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 remarkable coefficient, not exceeding 0.02, highlighting our commitment to superior engineering and performance.
