Nidec Sankyo producing many different type of ball screws series with high
quality requested. We also provide the technical documents. Such as ball
screw torque calculations, ball screw accuracy grades chart, ball screw
preload calculation, ball screw cad model...etc.
What is ball screw, the ball screw assembly consists of shaft and nut, each
with matching helical threaded, and balls which roll between these threaded
providing the only contact between the nut and shaft. The balls recirculating
by the designed internal or external deflectors.
The ball screw mechanical advantage including long-life, smooth moving, low
friction, high precision compare to the traditional screws.
We are specialized in manufacturing small ball screws (from ∅ 4mm), ball
screw selection procedure shall depends on the applications. The
recirculating ball screw mechanism and ball screw end machining could meet
the customer requested.
