The M-UMR5.25A 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 25 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.

M-UMR5.25A型精密双排球轴承孔径公制线性级采用钢结构，具有高稳定性和刚度。球轴承和精密研磨轴承表面提供特殊线性旅行,比100 - 200μrad角度偏差。UMR5系列轴承采用双排滚珠轴承，是承载600牛以下高负载的理想选择。移动的轴承由两个弹簧预压，以确保测微接触恒定，在25毫米的行程范围内实现平稳、无后摆运动。多个驱动选项覆盖精度定位范围。标准BM系列微米提供1μm敏感性,而DM系列微分μm 0.1微米的报价。对于位置锁定的粗运动，固定定位组件用两个相对的调节螺丝和锁紧螺母代替千分尺。一种可选的车厢锁定组件，包括一个螺丝，安装在舞台体对面的千分尺。可增加电动执行机构，实现精确的运动控制。该版本通过载体和舞台主体有一个清晰的孔。光圈对于光学、光纤或电缆设备的定位非常有用。丰富的孔模式，允许在舞台安装表面的组件安置很大的灵活性。两个阶段可以很容易地堆放在XY配置和安装到一个桌子或面包板(M-PBN安装基地需要)。多轴级配置容易装配使用EQ系列角支架。UMR级与UTR和URM旋转级、BGM测角仪和SL系列镜座兼容。
