Internal Gears

High-Precision Custom Internal Gears

As a premier all-around hardware processing manufacturer, XML specializes in the production of high-performance custom internal gears. Characterized by teeth cut into the inside surface of a cylinder or ring, internal gears are the foundational components of planetary gear systems. They are engineered to provide exceptional power density, enabling high-torque transmission within a highly compact and space-saving footprint.

Whether your project involves heavy-duty industrial machinery or high-precision robotics, our engineering team ensures every internal ring gear is manufactured to deliver smooth operation, reduced sliding friction, and long-lasting reliability.
