Take this beauty for a spin
Differentially pumped rotary platforms provide 360° of continuous rotary freedom through the wall of any vacuum system. The DPRF-series have two stages of differential pumping isolated by fluorocarbon seals on precision sealing surfaces. The rotating stage runs on high strength ball bearings. This allows the unit to be successfully used with manipulators and other precision positioning devices. All DPRF-series platforms come with a fine adjust worm drive and 0.1° vernier scale for easier and more accurate angle adjustment.
