Lead. Lead is the linear distance along the axis of the screw that is covered by one complete rotation (3600) of the screw. It is an important specification of a ball screw which determines linear travel and speed and load capacity. As the lead of ball screws increases, the linear distance covered and the speed increase.

The answer is calculated by multiplying the volume of the ball by the density of the material. Weight = Volume ⋅ Density. For example, calculate the weight of a two inch diameter lead ball: Volume =. 4 ⋅ π ⋅ R 3. 3. π, a universal constant = 3.1416. 4 ⋅ π = 12.566. R = Radius.
