Our dedicated pursuit of excellence is exemplified in our specialized steel pipe straightening process, which significantly reduces ovality and straightness errors of roller rings by an astounding 50% compared to the MT821 standard. We've decreased the idler's simulated frictional resistance coefficient from 0.025 to a mere 0.023, while radial runout has been improved from 1.0 mm to an impressive 0.35 mm. The post-straightening straightness accuracy is enhanced from 1.0 mm to an outstanding 0.20 mm. With an axial load exceeding 15 KN, as per the MT821 standard, our idlers achieve a precision grade lifespan surpassing an incredible 45,000 hours.
Our production line epitomizes technological superiority, achieving full automation through every stage, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless integration marks the zenith of efficiency and innovation.
Our idler shaft processing capitalizes on cutting-edge 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. Impressively, the distance between two milled grooves can be as minimal as 190mm,with a capability to accommodate workpieces up to an extraordinary maximum length of 2200mm.



1. Our idlers are meticulously designed for effortless replacement, with robust welding craftsmanship that ensures no wear on the idler shell, delivering a service life of no less than 45,000 hours.
2. Our idlers feature specialized bearings and stamped bearing housings with double-layer seals. This sophisticated design provides superior sealing, reduced rotational resistance, and enhanced longevity. We rely on elite bearings from renowned brands like SKF for superior performance.
3. The external dustproof capabilities of our idlers strictly adhere to MT821 - 1999 regulations, with waterproof performance also fully compliant with these rigorous standards.
4. Every steel material undergoes meticulous pre-treatment to achieve the St2-1/2 level. Welded structures are manufactured to meet the highest national welding standards, ensuring 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, underscoring our dedication to superior engineering and performance.
