Compare Robot Joint Actuators from China

How to read this table

Peak torque is a short-duration rating and rated torque is a continuous one. Manufacturers measure rated torque at a stated speed, ambient temperature and heat-sink plate, so two rated values are only comparable when those conditions match. Open the model page to see the conditions behind each figure before sizing a joint.

Gear ratio and gear type explain much of the difference between models. A low-ratio planetary joint is easier to back-drive and suits legged and contact-rich motion; a higher ratio raises output torque at the cost of speed and back-drivability. Compare the ratio together with rated speed rather than torque alone.

Supply voltage and communication decide how a joint fits your power and control architecture. Check the bus (CAN, CAN FD or EtherCAT), the control modes your firmware exposes and the encoder arrangement before mixing joints from different suppliers in one robot.

Each figure appears in the manufacturer document cited on the model page. Where a document does not state a value, the cell asks you to request it, so you can add it to your quotation request rather than infer it from a similar model.
