Get PriceThis smooth operation of leadscrews is indispensable to an array of applications. In some medical devices, machine axes run by leadscrews ... polyacetal nuts can keep the nut-screw friction coefficient to less than 0.10 for ... Higher loads at the screw-to-nut interface also necessitate more torque input to drive the leadscrew
Get PriceSep 06, 2011 Ball screw drives deliver excellent repeatability (backlash is dependent on ball bearing diameter, but typically ranges from 0.005 to 0.015 in.) and accuracy ( 0.004 in./ft for precision ball screws and 0.0005 in./ft for ball screws labeled precision-plus). Lead accuracy is the most common measure of ball screw accuracy
