In our quest for supreme quality, we have perfected a specialized steel pipe straightening process, drastically reducing ovality and straightness errors of roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is remarkably decreased from 0.025 to 0.023, and radial runout is substantially improved from 1.0 mm to a remarkable 0.35 mm. Post-straightening straightness is refined to an outstanding 0.20 mm. With an axial load exceeding 15 KN, aligned with MT821 standards, the lifespan of our idlers is elevated to surpass an extraordinary 45,000 hours.
Our production line stands as a beacon of technological excellence, achieving complete automation in every stage, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless and efficient operation highlights the zenith of industrial innovation.
Remarkably, our idler shaft processing utilizes cutting-edge fully automated production lines, executing precise operations with finesse, including servo-fixed-length cutting, end face turning, chamfering, snap ring groove cutting, center hole drilling, and milling flat grooves on the idler shaft. The precision allows for the distance between two milled grooves to be as small as 190mm,while accommodating workpieces up to a maximum length of an impressive 2200mm.



1. Our idlers are ingeniously designed for effortless replacement, with robust and enduring welding craftsmanship ensuring the idler shell experiences no wear throughout its extraordinary lifespan of no less than 45,000 hours.
2. Equipped with precision-engineered specialized bearings and stamped bearing housings featuring double-layer seals, our idlers offer exceptional sealing, minimal rotational resistance, and unmatched longevity. We trust only elite bearings from distinguished brands like SKF for superior performance.
3. Adhering strictly to MT821 - 1999 regulations, our idlers boast exemplary external dustproof capabilities, complemented by impeccable waterproof performance.
4. All steel materials undergo rigorous pre-treatment to reach the exemplary St2-1/2 level. Components involving welded structures are crafted with exacting precision, in strict accordance with national welding standards to align with the latest national criteria.
5. Our upper idlers proudly maintain a rotational resistance coefficient of precisely 0.022 or below, while the lower idlers excel, with coefficients not exceeding 0.02, underscoring our unwavering dedication to superior engineering and performance.
