Detailed Product Description

The ball screw assembly consists of a screw and a nut, each with matching helical
grooves, and balls which roll between these grooves between the nut and the screw
when the nut or screw is rotating. The balls are deflected by the deflector into
the ball return system of the nut and they travel through the return system
to the opposite end of the ball nut in a continuous path, and exit from the ball
return system into the ball screw and nut thread raceways continuously to recirculate
in a closed circuit.

The ball nut assembly: ball nut determines the load and life of the ball screw assembly.
The ratio of the number of threads in the ball nut circuit to the number
of threads on the ball screw determines how much sooner the ball nut will reach
fatigue failure (wear out) than the ball screw will. Ball nuts are manufactured
with two types of return systems.
