C&U continues to tackle common challenges in the rail transit bearing industry

Bearings, seemingly insignificant components, are actually core components that ensure the safe and smooth operation of subway trains. Behind them lies a deep legacy of precision manufacturing and technological innovation. Recently, "People's Urban Rail" featured a special report on C&U, focusing on this critical component, often called the "joint" of trains, revealing the profound technology hidden behind these "small bearings."

As a major player in the rail transit sector, C&U, backed by 2,230 patents and national science and technology awards, continues to overcome common industry challenges in rail transit bearings, including heat treatment, raceway reshaping, low friction, and electro-corrosion. This has resulted in breakthroughs in multiple dimensions, from materials to processes, improving bearing durability and reliability, and achieving independent control of high-end bearings.

Furthermore, leveraging its comprehensive bearing industry chain and global R&D network, C&U extends innovation to every aspect of R&D, manufacturing, and service. Renben's bearings are widely used on numerous domestic subway lines and are gradually expanding into the international market. With its solid "Chinese precision," Renben is helping rail transit achieve higher-quality development with greater safety, efficiency, and quietness.
