Ideally suited for 1"- 6" substrate heaters. CF or ISO flange, top or bottom mounted. Magnetically coupled lift and rotation for leak free service at UHV. - Magnetic drive rotation, 0-60 RPM. - 0-50mm magnetic lift, position indicator, optional limit switches, choice of manual, motor or pneumatic operation and longer stroke options. - UHV compatible and bakeable to 250°c. No plastics, O-rings or grease used in vacuum. - Easily detachable drive assembly for bakeout. - 18mm through bore for power, signal and cooling. - CF40 or larger mounting flange options. Note, with CF40 flange access to vacuum chamber is required to mount hardware. - Option of mounting to a CF40 Z-shift bellows, to provide substrate heater Z-axis positioning. - RF bias option. Can be upgraded later with RF kit. - Long life, low particulate radial ball bearings, used inside vacuum. Axial load produced by weight of cradle and substrate is supported outside vacuum, increasing vacuum side bearing life. - Nema 23 or 24 stepper motors, optional encoder and motor brands available. - Can be configured to suit customer's vacuum chamber, heater head, and sample transfer mechanisms.
