How to Calculate Unit Bearing Pressure for Thread?
Unit Bearing Pressure for Thread calculator uses Unit bearing pressure for nut = 4*Axial load on screw/(pi*Number of Engaged Threads*((Nominal diameter of screw^2)-(Core diameter of screw^2))) to calculate the Unit bearing pressure for nut, The Unit Bearing Pressure for Thread is the average pressure per thread acting on the contacting surface of the thread in a Screw-Nut pair. It is an important consideration for design applications. Unit bearing pressure for nut is denoted by Sb symbol.
How to calculate Unit Bearing Pressure for Thread using this online calculator? To use this online calculator for Unit Bearing Pressure for Thread, enter Axial load on screw (Wa), Number of Engaged Threads (z), Nominal diameter of screw (d) & Core diameter of screw (dc) and hit the calculate button. Here is how the Unit Bearing Pressure for Thread calculation can be explained with given input values -> 2.5E-5 = 4*131000/(pi*9*((0.05^2)-(0.042^2))).
