A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are …

Speed Considerations for Ballscrews. There are two different speed factors to consider when it comes to sizing ball screws; characteristic speed and critical speed. The characteristic speed depends on the limitation of the bearing system, and what speed it can withstand. This is an industry standard for a variety of bearings, indicating speed ...

So you can calculate the rotational vector component of force based on torque and the radius of the ballscrew. T = F1 x D/2, where: F1 is the vector component (tangent to the ballscrew) of the force applied by the screw onto the ball bearing. D is the diameter of the ballscrew. So, F1 = 2T / D. Linear force is produced because of the angle …
