PRF Series

Inline Planetary Gear Reducer

The PRF Series is an economical inline planetary gear reducer designed for servo and stepper motor applications where reliable performance and cost efficiency are important considerations.

Featuring helical planetary gearing and a durable internal structure, the PRF Series provides smooth operation and efficient power transmission for a wide range of automation and motion control systems.

A B5-style square output flange enables convenient mounting to machinery, indexing mechanisms, and linear actuator systems. Industry-standard motor interfaces allow easy adaptation to many servo and stepper motor types.

Frame sizes from 062 to 160 and backlash options of ≤8–10 arc-minutes provide flexibility across many machine designs where ultra-low backlash is not required. Special sealing and lubrication technologies help improve efficiency and heat dissipation, supporting reliable operation in continuous-duty automation environments.
