Linear Air Bearing Dovetail Stages

Print Friendly

Dovetail style linear air bearings are engineered and precisely lapped to match the rail and carriage angled sides creating a larger, stiffer bearing area for higher load capacity. These ultra-precision stages are designed for manual translation with a fully supported dovetail rail which can be end-mounted if desired. Carriages are available from 4 inches (100mm) up to 10 inches (250mm) wide, and rail lengths are available up to 42 inches (1067mm) for extended travel.
