Web13 jun. 2014 · 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 … Webzero lead, both of which are unacceptable. Things to Remember When Cutting Threads on a Lathe.
