LSN series are high torque housed component gear set combined with a precision cross roller output bearing & flange. It is a very compact, robust and easy to use gearhead solution. The LSN II series is available in 5 sizes with ratios 50:1 to 160:1. If your application does not require high torque, LSN series gearhead is a great alternative gearhead. There is also a lightweight version.
LSN series is the lightweight product line, designed to reduce the weight of the mechanical equipment itself and facilitate the lightweight construction of industrial robots. It enables higher speeds and increased payload capacity for industrial robots.
