The planetary gearbox SDP6,8 has been renewed.

Added fixing screw threads to the mounting surface.

In the case of the small path reducer, it was structurally difficult to tap the mounting surface. In response to feedback that it was difficult to secure when using the geared motor, we added threading to the mounting surface. *We have renewed our website. Please take a look at our other products as well.

Ceramic effects in planetary gear reducers

Significantly improved durability of the planetary gear reducer with ceramic carrier pins.

The lifespan of a planetary gearbox depends on how it is used, but generally, it becomes difficult to transmit power due to wear on the output shaft bearings, carrier shaft, and gears. Based on our past performance, the component that wears out first among the consumable parts is the carrier shaft (pin). With the spread of brushless motors, efforts have been made to extend the lifespan of motors; however, the gearboxes have not kept pace. To respond to the demand for longer-lasting motors, our company has equipped ceramic carrier shafts (pins), significantly enhancing the durability of the gearboxes. ★ Models compatible with ceramic carrier pins: - SDP13 series - SDP16 series - SDP31 series For the results of the durability comparison test between standard products and those equipped with ceramic carrier pins in the SDP31, please download the PDF document from the link below.
