Enables high-speed motion, fast starts,
and quick stops.
Improves takt time of horizontal articulated robots
Customers are looking for low-inertia Z axes to improve the takt time of horizontal articulated robots. This product is more compact and lightweight than its predecessors, achieving low inertia and helping to optimize designs.
Provides Both Precision and Speed

Reducing the nut's outer diameter
while keeping the shaft the same
size lowers the weight and can
shorten takt time.
Using a smaller and lighter end
shaft and peripheral device
reduces the load on the motor,
which reduces the amount of heat
generated and enables equipment
to run even longer than before.
Product Structure
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 is capable of performing three types of motion (rotational, linear, and spiral) with a single shaft by rotating or stopping each nut.
