Linear Air Bearing Rectangular Stages

Print Friendly

ABTech designed these ultra-precision linear air bearing boxway slides with a fully preloaded air bearing carriage to provide resistance to offset loading and stiffness to support heavier loads or stacked configurations. The tight form geometry control of the linear box rails and the central placement of the optional linear drive ensure both accuracy and minimal offset errors in a low profile design. Standard carriages sizes are 6 inches (150mm) up to 10 inches (250mm) wide, and rail lengths are available up to 42 inches (1067mm) for extended travel.
