The low friction within ball screw designs means that a high mechanical efficiency is delivered compared to that of lead screw designs. A typical ball screw may be 90 percent efficient, versus 50 percent efficiency of a lead screw of equal size. Ball screw specification is often a result of an applications requirement to have smooth, accurate and repeatable linear movement. A recent application for Abssac specified a precision ball screw within an electronic microscope that placed a precision guillotine against test pharmaceutical materials.Give us a call to discuss where our range of ball screws can assist in your designs. www.abssac.co.uk
