EFor accuracy of Ball Screws, see P.2223 and P.2224. EFor details of Support Units, see P.753 ~ P.778. ECautions: Do not let the nuts overrun or remove the nuts from the screw shafts. It may cause the balls to fall out or damage the ball recirculation parts. EDo not tilt the ball screw assembly since the nut may spin off from the shaft due to its own weight. EUse one of the support unit accessory collars on the fastening nut side. QCombination with Support Units EOther than the part numbers shown above, a wide variety of Support Units are also available.
