China ball screws

Why do the ball screws require ball recirculation parts?

In case of a ball bearing, its steel balls roll only in a circular groove, thus there is no way for steel balls to go out of it. However, since the groove in the ball screw is helical, its steel balls roll along the helical groove, and, then, they may go out of the ball nut unless they are arrested at a certain spot.
Thus, it is necessary to change their path after they have reached a certain spot by guiding them, one after another, back to their “starting point” (formation of a recirculation path). The recirculation parts play that role.

By providing steel balls in between the screw shaft and the nut (grooves), and the balls roll on the grooves (i.e.,Change to rolling contact from sliding contact to reduce friction. Refer to the illustration below.).

What is friction force? (Sliding and rolling friction)

When you want to slide a box sitting on a floor, it does not move while your pushing force is yet too small (static frictional force). But, it starts moving when the pushing force has reached a certain level. In order to keep the box moving on, you need to maintain your pushing force at its dynamic frictional force, which is far less than the static friction force.
As described above, the friction force is the force that two objects exert upon each other through their contact surface and hinder each other's relative movement when they are in contact.
The intensity of frictional force varies with the state of contact. A friction force of rolling contact is usually smaller than that of sliding contact.
