Our pursuit of top-tier quality is reflected in our specialized steel pipe straightening process, which notably reduces ovality and straightness errors of roller rings by an impressive 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is significantly lowered from 0.025 to 0.023, while radial runout is enhanced from 1.0 mm to an outstanding 0.35 mm. Post-straightening straightness is refined from 1.0 mm to an exceptional 0.20 mm. With an axial load surpassing 15 KN, in accordance with the MT821 standard, our idlers' lifespan is elevated to a superior precision grade, exceeding an extraordinary 45,000 hours.
Our production line epitomizes technological excellence, achieving full automation at every stage, including straightening, pipe cutting, boring, stamping, welding, and assembly. This seamless integration showcases the pinnacle of efficiency and innovation.
Our idler shaft processing utilizes cutting-edge fully automated production lines, expertly performing 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 capability to handle workpieces up to an impressive maximum length of 2200mm.



1. Our idlers are ingeniously designed for effortless replacement, with welding craftsmanship that is both robust and enduring. This ensures no wear on the idler shell throughout its extraordinary service life, which spans no less than 45,000 hours.
2. Equipped with specialized bearings and stamped bearing housings featuring double-layer seals, our idlers deliver exceptional sealing, minimal rotational resistance, and extended longevity. We utilize premier bearings from renowned brands like SKF to ensure unrivaled performance.
3. The idlers' external dustproof capabilities are in strict compliance with the MT821 - 1999 regulations, and their waterproof performance meets these demanding standards in full.
4. Every steel material undergoes meticulous pre-treatment to achieve the St2-1/2 level. Parts requiring welded structures are fabricated in strict adherence to national welding standards, ensuring structural 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 boast an even more impressive coefficient, not exceeding 0.02, underscoring our unwavering dedication to superior engineering and performance.
