The D1430 is a linear air bearing specifically designed to operate in a very vacuum environment, such as in a wafer ion inplantation chamber. The linear stroke length can be up to 508mm in a vertical orientation, and rotation is also possible. The wafer chuck can be attached at one end of the hollow shaft and a linear motor to the other end.
