Our relentless pursuit of quality perfection extends through our specialized steel pipe straightening process, markedly reducing ovality and straightness variance of roller rings by an impressive 50% in comparison to the MT821 standard. The idler's simulated frictional resistance coefficient is significantly lowered from 0.025 to 0.023, while radial runout is optimized from 1.0 mm to a remarkable 0.35 mm. Post-straightening straightness enhances from 1.0 mm to an outstanding 0.20 mm. With an axial load exceeding 15 KN, as per the MT821 standard, our idlers achieve a superior precision grade with a service life surpassing an extraordinary 45,000 hours.
Our state-of-the-art production line stands as a testament to technological excellence, achieving seamless automation at every phase, including straightening, pipe cutting, boring, stamping, welding, and assembly. This immaculate process represents the zenith of efficiency and groundbreaking innovation.
Our idler shaft processing leverages the latest fully automated production lines, executing meticulous 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. The distance between two milled grooves is precision-engineered to be as minimal as 190mm,capable of accommodating workpieces up to an impressive maximum length of 2200mm.



1. Our idlers are ingeniously engineered for streamlined replacement, employing robust welding techniques that safeguard the idler shell from wear throughout its remarkable service life, extending 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 prolonged durability. We employ top-tier bearings from distinguished brands such as SKF to ensure peerless performance.
3. The exterior dustproof capabilities of our idlers rigorously conform to the MT821 - 1999 standards, guaranteeing superior waterproof performance that fully aligns with these rigorous specifications.
4. Every steel material is subjected to rigorous pre-treatment to attain the St2-1/2 level. Parts requiring welded structures are produced in strict accordance with national welding standards, ensuring structural compliance with the latest national criteria.
5. The rotational resistance coefficient of the upper idlers is precisely calibrated to 0.022 or below, while the lower idlers achieve an even more impressive coefficient, not exceeding 0.02, underscoring our unwavering commitment to superior engineering and performance excellence.
