Precision internal (ring) gears for planetary and epicyclic gear system applications.
Internal Gear
Internal gears have teeth cut on the inside of a ring, meshing with external gears (planet gears) inside them — a key component in planetary gear systems, providing compact, high-torque speed reduction.
Compact High-Torque Design
Core component for planetary and epicyclic gear systems.
