Abstract
A lead screw and follower assembly employs a specially formed helical thread and a follower assembly employing bearings which ride on the several surfaces of the helical thread, thereby providing essentially frictionless motion and also preventing deflection of the lead screw during operation. The lead screw is preferably formed of a synthetic material such as polycarbonate incorporating glass fibers and the bearings are either roller or ball bearings.
