Linear Stage, Double-Row Ball Bearing, Aperture, 16 mm Travel, M3 and M4

The M-UMR5.16A Precision Double-Row Ball Bearing Aperture Metric Linear Stage features steel construction for high stability and rigidity. The ball bearings and precision-ground bearing surfaces provide exceptional linear travel, with angular deviation better than 100-200 μrad. UMR5 Series Stages have double-row ball bearings making them an excellent choice for carrying high loads up to 600 N. The moving carriage is preloaded by two springs to ensure constant micrometer contact for smooth, backlash-free motion over a 16 mm travel range. Multiple drive options cover the range of precision positioning. Standard BM Series Micrometers provide 1 μm sensitivity, while DM Series Differential Micrometers offer 0.1 μm. For coarse motion with position locking, a fixed positioning kit replaces the micrometer with two opposing adjustment screws and lock nuts. An optional carriage locking kit includes a screw that mounts in the stage body opposite the micrometer. Motorized actuators can be added for precision motion control. This version has a clear hole through the carrier and stage body. Apertures are very useful for the positioning of optics, fiber optics, or cabled devices. Generous hole patterns allow great flexibility in component placement on the stage mounting surface. Two stages can be easily stacked in an XY configuration and mounted to a table or breadboard (M-PBN Mounting Base required). Multi-axis stage configurations are easily assembled using EQ Series Angle Brackets. UMR Stages are compatible with UTR and URM Rotation Stages, BGM Goniometers, and SL Series Mirror Mounts.
