Apr 24, 2017 · Rpm stands for rotations per minute and is used to quantify the speed at which an object spins, such as a motor or a centrifuge. Linear speed measures the actual distance traveled, often in feet per minute. Because a rotation always covers the same distance, you can convert from rpm to linear distance if you can find

Ball Screw Column Strength and Critical Speed End Fixity. End fixity refers to the method by which the ends of the screw are supported. The degree of end fixity is related to the amount of restraint of the ends of the screw. It is important to determine the proper end fixity in order to determine the appropriate screw size for a give appliion.
