Instead, the ball nut is matched to the screw by adjusting a variable dimension. This can be accomplished in several ways. One preloading method uses a double-nut system. Double nuts wedge the nut ...

As a rule, double nuts (two-point contact ... support-bearing arrangement can change rigidity. Suppose that a ball screw system with a total stiffness = 97 N/mm needs to increase by at least ...

We’ve got mixed feelings about a new video from [AndysMachines] that details how he makes custom ball screws. On the one hand, there’s almost zero chance that we’ll ever have an opportunity ...

These are simple devices that are essentially a steel screw thread and a brass nut that travels on it. However, for maximum precision, you’d like to use a ball screw. These are usually very ...

Central to the upgrade is a precision ground stainless steel slideway that guides “carriages” up and down via a system of recirculating ball bearings. This mechanical arrangement includes a so-called ...
