Our dedication to exceptional quality is evident in our advanced steel pipe straightening process, which dramatically reduces ovality and straightness variations of roller rings by an astounding 50% compared to the MT821 standard. The idler's simulated frictional resistance coefficient is impressively lowered from 0.025 to 0.023, while radial runout is optimized from 1.0 mm to an extraordinary 0.35 mm. Post-straightening straightness improves significantly from 1.0 mm to a remarkable 0.20 mm. With an axial load exceeding 15 KN per the MT821 standard, our idlers achieve an elevated precision grade with a service life surpassing an incredible 45,000 hours.
Our production line stands as a testament to technological excellence, achieving full automation across all stages including straightening, pipe cutting, boring, stamping, welding, and assembly. This flawless process embodies peak efficiency and groundbreaking innovation.
Our idler shaft processing embraces state-of-the-art fully automated production lines, executing intricate 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 with precision. The distance between two milled grooves can be as small as 190mm,accommodating workpieces up to a maximum length of 2200mm.



1. Our idlers are brilliantly designed for seamless replacement, with sturdy welding techniques that ensure the idler shell remains unscathed throughout its remarkable service life, reaching at least 45,000 hours.
2. Featuring specialized bearings and stamped bearing housings with dual-layer seals, our idlers guarantee exceptional sealing, minimal rotational resistance, and extended longevity. We use premium bearings from elite brands like SKF for unrivaled performance.
3. Our idlers' external dustproof capabilities strictly adhere to MT821 - 1999 regulations, ensuring superior waterproof performance that fully meets these rigorous standards.
4. Each steel material undergoes comprehensive pre-treatment to achieve the St2-1/2 level. Components involving welded structures are manufactured in strict conformance with national welding standards, ensuring structural compliance with contemporary national criteria.
5. The upper idlers have a finely tuned rotational resistance coefficient of precisely 0.022 or lower, while the lower idlers boast an even more remarkable coefficient, not exceeding 0.02, highlighting our dedication to superior engineering and performance.
