    The AGK Ball Screw Drive Unit from Bosch Rexroth Corp., Charlotte, N.C. (boschrexroth-us.com), delivers up to five times the speed of traditional ball screws when used for extended-length applications. A high-performance ball screw in a rigid aluminum housing with specially designed screw supports generates speeds up to 96 m/min, even in extreme environments. And the bearings reduce screw whip. The device is available in accuracy Classes 5, 7, and 9, and Sizes 20x, 32x, and 40x.
