Ball recirculating systems needs the maximum geometrical precision, to obtain a smooth operation at all speeds with a minimum friction.

IPIRANGA ground ballscrews are manufactured in two different types of internal return, so we obtain compact nuts with out external projections:

-Internal ball return with radial deflector, for short pitches, each internal circuit is independent and it has a complete turn circumference.

-Internal ball return by axial Liners for long pitches. This has a single internal circuit of several turns, with return by a hole through the nut and the return of the ball by means of two liners.
