Our commitment to superior quality remains steadfast as we engage in specialized straightening processes for steel pipes. This meticulous approach significantly reduces the ovality and straightness errors of roller rings by an astounding 50% compared to the MT821 standard. We've impressively decreased the idler's simulated frictional resistance coefficient from 0.025 to 0.023. Radial runout has been enhanced from 1.0 mm to a remarkable 0.35 mm, while post-straightening straightness is improved from 1.0 mm to an outstanding 0.20 mm. With an axial load exceeding 15 KN, as per the MT821 standard, our idlers' lifespan is elevated to surpass an impressive 45,000 hours.
Our production line is a beacon of technological advancement, realizing complete automation in each step of the idler production process. From straightening, pipe cutting, boring, stamping, welding, to assembly, every operation is seamlessly integrated, epitomizing efficiency and pioneering innovation.
We employ cutting-edge, fully automatic production lines in the processing of idler shafts. These lines perform precise operations including servo-fixed-length cutting, end face turning, chamfering, snap ring groove cutting, center hole drilling, and milling flat grooves on the idler shaft. Impressively, the distance between two milled grooves can be as minimal as 190mm,with our capacity extending to process workpieces up to a substantial maximum length of 2200mm.



1. Our idlers are designed for seamless replacement, with robust welding craftsmanship that ensures no wear on the idler shell throughout its impressive standard service life, lasting no less than 45,000 hours.
2. Our idlers are equipped with specialized bearings and stamped bearing housings that feature double-layer seals. This innovative design guarantees exceptional sealing, minimal rotational resistance, and remarkable longevity. For top-notch performance, we rely on elite bearings from reputable brands like SKF.
3. The idlers' external dustproof capabilities are in strict compliance with the MT821 - 1999 regulations, and their waterproof performance equally adheres to these rigorous standards, ensuring reliability under any condition.
4. Every steel material undergoes comprehensive pre-treatment to achieve the St2-1/2 level. For parts involving welded structures, manufacturing strictly aligns with national welding standards, ensuring structural conformity with the latest national criteria.
5. The rotational resistance coefficient of upper idlers is precisely 0.022 or below, while the lower idlers maintain a coefficient not exceeding 0.02, underscoring our dedication to superior engineering and unrivaled performance.
