Product Description

As the manufacturer behind the BMT Bearings brand, we have been engaged in bearing production and engineering since 2004. Based on real manufacturing experience with automated grinding lines and ISO-certified systems, our Double Row Cylindrical Roller Bearings are developed for industries where stability and reliability are critical.

In demanding environments such as steel mills, mining machinery, gearboxes, pumps, and heavy electric motors, bearing performance directly affects equipment lifespan. Our design focuses on improving load distribution, heat resistance, and long-term operational stability.

Through optimized roller geometry and raceway contact structure, internal stress is reduced and load distribution across both rows is significantly improved, resulting in better durability under continuous operation.
