Many applications require high torque, yet have limited space – such as robotics, rotary tables and machine tools. In addition, fast and precise positioning movements have to be carried out with high payloads and without backlash. To meet such demands, Nabtesco has developed the RV-N series of lightweight, compact and heavy-duty precision gears.

According to the company, the compact design is achieved through a main bearing with an integrated inner race. High power density is possible due to reinforcement of the eccentric shaft bearing. In addition, special heat treatment of the components during production ensures high thermal stability and longer service life.
