Our relentless quest for superior quality is evident in our unique steel pipe straightening process, which significantly reduces ovality and straightness deviations of roller rings by a remarkable 50% compared to the MT821 standard. The idler’s simulated frictional resistance coefficient is impressively decreased from 0.025 to 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 outstanding 0.20 mm. With an axial load exceeding 15 KN, as per MT821 standards, our idlers achieve a heightened precision grade with a service life surpassing an extraordinary 45,000 hours.
Our production line stands as a paragon of technological excellence, achieving full automation across all phases, including straightening, pipe cutting, boring, stamping, welding, and assembly. This impeccable process epitomizes the pinnacle of efficiency and innovation.
Our idler shaft processing employs state-of-the-art fully automated production lines, executing meticulous 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 distance between two milled grooves can be as diminutive as 190mm,and capable of accommodating workpieces up to a maximum length of 2200mm.



1. Our idlers are meticulously engineered for straightforward replacement, with robust welding techniques ensuring that the idler shell endures no wear throughout its impressive service life, which spans no less than 45,000 hours.
2. Featuring specialized bearings and stamped bearing housings with double-layer seals, our idlers deliver exceptional sealing, minimal rotational resistance, and prolonged longevity. We employ premium bearings from world-renowned brands like SKF for performance that is second to none.
3. The external dustproof prowess of our idlers strictly adheres to the stringent MT821 - 1999 regulations, ensuring exceptional waterproof capabilities that fully comply with these demanding standards.
4. Each steel material undergoes rigorous pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are crafted in stringent accordance with national welding standards, guaranteeing structural integrity aligned with the latest national criteria.
5. The rotational resistance coefficient of the upper idlers is precisely calibrated to 0.022 or below, while the lower idlers maintain an even more impressive coefficient, not exceeding 0.02, underscoring our commitment to superior engineering and performance.
