Our relentless dedication to quality shines through in our specialized steel pipe straightening process. This precise technique reduces ovality and straightness errors of roller rings by an astounding 50% compared to the MT821 standard. The idler's frictional resistance coefficient is notably reduced from 0.025 to an impressive 0.023, while radial runout is refined from 1.0 mm to an extraordinary 0.35 mm. Post-straightening straightness is improved from 1.0 mm to a remarkable 0.20 mm. With an axial load capacity exceeding 15 KN, as per the MT821 standard, the lifespan of our idlers is enhanced to a superior precision grade, surpassing an exceptional 45,000 hours.
Our production line exemplifies technological prowess, achieving complete automation across every stage, including straightening, pipe cutting, boring, stamping, welding, and assembly. This streamlined process reflects the zenith of efficiency and innovation, setting a new standard in the industry.
Our idler shaft processing benefits from cutting-edge fully automated production lines, expertly handling precise tasks 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. Astonishingly, the distance between two milled grooves can be as little as 190mm,with the capability to accommodate workpieces up to a substantial maximum length of 2200mm.



1. Our idlers are ingeniously designed for easy replacement, backed by robust and enduring welding craftsmanship that ensures no wear on the idler shell throughout its impressive service life, which spans no less than 45,000 hours.
2. Our idlers incorporate specialized bearings and stamped bearing housings with double-layer seals, guaranteeing exceptional sealing, minimal rotational resistance, and extended longevity. We utilize elite bearings from prestigious brands such as SKF for unparalleled performance.
3. Adhering to MT821 - 1999 regulations, our idlers' external dustproof capabilities are strictly compliant, and their waterproof performance also meets these stringent standards, ensuring reliability in all conditions.
4. Every steel material undergoes meticulous pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are manufactured in accordance with national welding standards, ensuring structural integrity aligned with the latest national criteria.
5. The rotational resistance coefficient of the upper idlers is precisely capped at 0.022 or below, while the lower idlers maintain an even more impressive coefficient, not exceeding 0.02, underscoring our dedication to superior engineering and performance.
