Application with BNS-V

Application Example Scara-Robot with Ballscrew-Spline BNS-V

 

Customers are looking for low-inertia Z axes to improve the circle time of horizontal articulated robots.

With this new type, the smaller outside diameter of the nut reduces the weight while the shaft diameter remains the same, thus enabling shorter cycle times. Together with the use of a slimmer peripheral connection construction, the stress on the motor and the waste heat are reduced. Applications with the new BNS-V achieve longer service lives.

The BNS-V is a combined product with a ball screw nut and ball spline nut inserted directly into the dedicated ball screw and ball spline grooves on the shaft. This ball screw/spline can perform three types of motion (rotational, linear, and spiral) with a single shaft by rotating or stopping each nut.
