Sumitomo Astero G9B25KH gear head is a planetary gear head designed to pair with Sumitomo Astero motors to deliver higher torque at reduced speed in automation applications. Part of the Astero G9B KH family, the G9B25KH supports multiple gear ratios (24 options, from 1:3 to 1:200) to match torque and speed requirements. The output shaft diameter is 15 mm, and the assembly is designed for motor-frame compatibility across sizes 6, 7, 8, 9A, 9B, and 9C. Weight is around 1.40 kg (for the G9B25KH through G9B60KH range). Astero gear heads are designed to be detachable from the motor for easy handling and assembly.
