R1 series ground precision ball screw assembly

Hiwin’s R series covers precision ground ball screws, where the thread is ground rather than rolled to give high lead accuracy. A nut with recirculating balls rides on the screw, which turns rotary motion from a servo motor into linear travel with low friction and high efficiency. The assembly is sold with end machining for bearing supports, in a range of diameters and leads, with preload options to remove backlash. Ground ball screws are used on machine tool feed axes, semiconductor equipment, measuring machines, and precision positioning stages. The designation ‘R1’ in the input could not be matched to a single catalogued item, so the entry gives the series.
