Engineering Calculators

The calculator derives the expected life in inches of travel (Inch Calculator), or the expected number of revolutions (Metric Calculator) of a ball nut operating at a load which is different than the rated dynamic load.

The calculator derives the expected life in inches of travel (Inch Calculator), or the expected number of revolutions (Metric Calculator) of a ball nut operating at a load which is different than the rated dynamic load.

The calculator takes the input shaft speed and the torque required for a given load and derives the amount of horsepower or kilowatts expended. It can also back-calculate the torque or speed from a given power requirement.
