Power Screws Design Equation and Calculator | Engineering …

Ball and tapered-roller thrust bearings can be used to reduce the collar torque. The starting torque is obtained by substituting the static coefficients of friction into the above equations. Since the sliding coefficient of friction is roughly 25 percent less than the static coefficient, the running torque is somewhat less than the starting torque.
