Working closely with experienced manufacturers in China, Yongxing provides both standard and custom solutions tailored to meet the specific needs of global distributors, repair shops, and equipment operators.

The Importance of High-Quality EX400 Track Rollers

Track rollers, such as the EX400 track roller, play a vital role in the functionality of large excavators. They support the machine’s weight, guide the track during movement, and help absorb shocks from rough terrain. A high-quality track roller must therefore be built to withstand:

Extreme pressure and load stress

Abrasive dust and dirt common in construction sites

Corrosion from moisture and chemicals

The Hitachi EX400 bottom roller, in particular, is engineered to maintain alignment and reduce wear on other undercarriage components. At Yongxing, each roller undergoes strict quality control processes — including hardness testing, seal integrity checks, and lubrication verification — to ensure it meets or exceeds OEM specifications.

These rollers are manufactured using forged steel and precision bearings, ensuring long-lasting performance even under the toughest operating conditions.
