[New Product] Achieved high torque support of 2.5N·m equivalent to a 60-square reduction gear in a small size of Φ31!

The SDP31 has a long track record of use in residential equipment and automotive devices. This time, by using ceramic in the pillar section of the planetary gearbox, we have significantly improved torque and reliability. It is now possible to achieve equivalent torque with about 1/4 the volume of a 60-square gearbox, which can assist in the miniaturization and space-saving considerations of your products. With this significant increase in performance and reliability, it is now possible to use it in industrial equipment and other applications. Additionally, by combining it with a brushless motor, it is possible to fully utilize the motor's performance. 【Features】 Compact and space-saving: Achieves high torque equivalent to a 60-square gearbox with about 1/4 the volume. Long lifespan: Passes a 3000-hour durability test using ceramic carrier pins. High torque: Capable of continuous use with a high torque of 2.5N·m, which is 2.5 times that of the conventional SDP31. *For more details, please download the PDF or contact us.
