The M-460A-X-MIC is a special bundle of three M-460A-X Linear Stages included with all required SM-13 Micrometers. The M-460A-X features all aluminum construction with hardened ball bearings running along opposing pairs of polished and hardened stainless steel rods. This offers exceptional straightness of travel, but a lower load capacity than our crossed-roller bearing stages. The SM-13 Vernier Micrometer is a standard drive for most Newport stages, including the 460A-Series stages. It has a 13 mm travel range and a 9 lb. load capacity. The SM-13 has a 0.5 mm pitch (50.8 TPI) threads and read directly in increments of 10 μm, with vernier reading of 1 μm.
