Adopted high-quality wear-resistant steel material with high hardness and strong toughness, featuring excellent anti-fracture and anti-fatigue performance. It is suitable for heavy-load scenarios such as Sinotruk 9-speed gearboxes.

Precision forming with small dimensional tolerance ensures easy installation. It effectively isolates planetary gears and planet carriers to reduce end face wear.

The unique oil groove design enhances lubrication circulation, lowers friction temperature rise and prevents bearing ablation.

With high temperature resistance and wear resistance, it maintains no deformation during long-term operation, greatly reducing gearbox failure rate and offering high cost performance.
