Planetary Gear Reducers for CNC Machines

When the reducer transmits power:

A planetary gear reducer consists of a sun gear, planetary gears, ring gear, and precision bearings housed in a compact structure. Through straight-tooth planetary gear transmission and optimized gear meshing, torque is evenly distributed across multiple gears, ensuring smooth speed reduction, high torque output, and precise motion control for CNC and automation systems.

The planetary gear set distributes load evenly across multiple gears, significantly increasing torque capacity while reducing stress on individual gear teeth.
The compact coaxial structure and hardened gear profiles provide high torsional rigidity, low backlash, and stable transmission accuracy during continuous operation.

Applications

Applications of Planetary Gear Reducer Longqiao linear guides are used in many types of equipment, for example:

By combining different series of rails and blocks, we can help you choose suitable linear guides for both new machines and retrofit projects.
