Acme Screw Engineering Resources

Helpful acme screw related technical resources. 

Engineering Calculators

Unit pressure on the nut (P) and surface velocity at the nut/screw interface (V) limit the use of a particular material in an application because of the resulting heat build up and accelerated wear. All Nook Industries nut materials have a limiting PV value.

This calculator compares the actual operating load and speed against the PV rating of the chosen material. Calculations for both Nook BronzAC and PlastAC materials in inch and metric units are available.
