Our tireless quest for superior quality is demonstrated in our specialized steel pipe straightening process. This precise method reduces ovality and straightness deviations of roller rings by an extraordinary 50% compared to the MT821 standard. The idler's frictional resistance coefficient has impressively decreased from 0.025 to 0.023, while radial runout has been refined from 1.0 mm to an exceptional 0.35 mm. Post-straightening straightness is improved from 1.0 mm to a remarkable 0.20 mm. Our idlers boast an axial load exceeding 15 KN, as per the MT821 standard, with a lifespan surpassing an astonishing 45,000 hours.
Our production line epitomizes technological excellence, achieving full automation across all stages, including straightening, pipe cutting, boring, stamping, welding, and assembly. This flawless process reflects the zenith of efficiency and innovation.
Our idler shaft processing employs cutting-edge fully automated production lines, expertly handling precise 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. Notably, the distance between two milled grooves can be as minimal as 190mm,with the capacity to accommodate workpieces up to an impressive maximum length of 2200mm.



1. Our idlers are meticulously designed for easy replacement, with robust and enduring welding craftsmanship that ensures no wear on the idler shell throughout its exceptional service life, guaranteed to last no less than 45,000 hours.
2. Our idlers incorporate specialized bearings and stamped bearing housings with double-layer seals. This advanced design ensures outstanding sealing, minimal rotational resistance, and extended longevity. We utilize elite bearings from renowned brands such as SKF for unparalleled performance.
3. The idlers' external dustproof capabilities strictly adhere to the MT821 - 1999 regulations, and their waterproof performance fully complies with these rigorous standards.
4. Every steel material undergoes precise pre-treatment to achieve the St2-1/2 level. Parts involving welded structures are manufactured in strict alignment with national welding standards, ensuring structural integrity that aligns 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 impressive coefficient, not exceeding 0.02, underscoring our commitment to superior engineering and performance.
