NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President & CEO: Toshihiro Uchiyama) has developed a new actuator unit that delivers lift-rotation Z-θ motion (coaxial rotation and linear motion) in a compact rod-shaped package.
The versatile unit uniquely integrates motor, ball screw with spline, and brake mechanism to achieve high performance Z-θ motion with a small footprint. A waterproof upper structure enables the unit to handle challenging splash-and-spray (wet) manufacturing environments.
NSK will be exhibiting a working prototype at International Robot Exhibition 2019 (iREX 2019), to be held at Tokyo Big Site from December 18-21, 2019.
The Z-θ actuator offers a new value proposal of increasing productivity per square meter of floor space. NSK is preparing to launch the product in the near future, and units are available for trial implementation and verification testing by customers.
