EBT Series Precision Linear Translators
EBT Series precision linear translators provide reliable single-axis (Z only) motion in ultra-high vacuum environments. Designed for stability and mechanical strength, the EBT Series supports demanding payload requirements while maintaining smooth, precise positioning. Bellows inside diameters up to 6.3″ are available, with standard base and traveling flange sizes of 8″ O.D. Other flange diameters can be provided on request.
The Z-axis drive utilizes a precision Acme screw with a 4:1 gearbox, offering accurate motion control and position indication to 0.001″ divisions. Multiple drive options are available, including manual and MS-LS, along with enhancements such as EDL, ZPI, HMP, and POGO.
