Sumitomo Cyclo BBB is a family of compact cycloidal reducers by Sumitomo Drive Technologies (Japan/USA). The BBB series (Brute, Bearings, Balanced) offers increased durability and compact dimensions compared to the classic Cyclo 6000 series. The cycloidal mechanism eliminates tooth sliding, achieving up to 93% efficiency and very high shock load resistance (up to 500% of rated torque).
Output torque depending on size: from 12 Nm (size 0) to 2800 Nm (size 6). Single-stage ratios: 6:1, 11:1, 17:1, 29:1, 43:1, 59:1, 87:1. Backlash: <=1 degree (standard) or <=0.5 degree (precision). Configurations: flange, shaft, right-angle. Housing: aluminum or cast iron.
Cyclo BBB is used in mobile robots, conveyor systems, CNC machine tools, feeders, and packaging equipment. Notable for long needle bearing life (without inner race), quiet operation, and vibration resistance. Lubrication: oil or grease with maintenance-free lifetime option.
Rotary Actuator · serves as: Gear Reduction, Torque Transmission, Motion Transmission.
Which group Sumitomo Cyclo BBB belongs to and how it is built
This subcategory covers components responsible for highly accurate torque transmission and speed reduction in robots, manipulators, and joint modules.
A rotary actuator is a component responsible for generating controlled rotational motion. It can be implemented as an electromechanical, pneumatic, or hydraulic module, depending on the application. In robotics, rotary actuators are used in joints, positioning mechanisms, manipulator drives, and automation equipment where angular motion is required.
