In ballscrews the friction coefficinet is very low due to the rolling that exits between elements. The efficiency depends on several working conditions and the geometrical characterics and accuracy used in its manufacture. IPIRANGA ground ballscrews have a high quality tecnical process; to obtain a high mechanical efficiency near to a 100% determined by the helix angle and friction.

After running the assembly, the friction angle is 0,23º for qualities IT1 - IT3 & IT5
