How does the preload affect performance?

Preload reduces axial play to zero, allowing for smooth operation with low torque and high rigidity.

What materials are used for the ball screw?

The shaft is made of SCM450, S55C, or CF53, and the nut is made of SCM415 or 20CrMo, both hardened to HRC58-62.

What is the lead time for delivery?

Lead time depends on the required quantity and is negotiated. Peak season and off-season lead times are approximately one month.
