Description


The PR-70TM is a compact rotation stage with unlimited travel and a 1 inch aperture. Steel crossed roller bearings ensure smooth motion and high stability. The PR-70TM can be combined with the linear PPX-50 or PPS-70 (51mm travel and up) stages without an adapter bracket. Versions capable of operation in vacuum (10-6 mbar) are available. The PR-70TM is compatible with the NanoDrive controller.
