Inline Planetary Gearbox Solutions
Inline planetary gearboxes are designed for servo-driven automation systems where the motor shaft and output shaft remain on the same axis. This structure provides compact installation, high torque density, stable transmission, and precise motion control for CNC machinery, robotics, packaging equipment, and industrial automation lines.

Inline planetary gearboxes are preferred when the motor and driven mechanism can be arranged on the same axis. They are often selected for compact coaxial transmission, simple mounting, and efficient torque transfer. If the machine requires a 90-degree input-output direction or needs to save axial space, a right angle planetary gearbox may be more suitable.

Before selecting a gearbox, confirm output torque, reduction ratio, backlash requirement, motor frame size, input speed, radial load, axial load, duty cycle, and installation space. For servo-driven equipment, the gearbox should also match the motor shaft, flange size, and required positioning accuracy.
