The M-UMR8.51 Precision Double-Row Ball Bearing 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. UMR8 Series Stages have double-row ball bearings making them an excellent choice for carrying high loads up to 900 N. The moving carriage is preloaded by two springs to ensure constant micrometer contact for smooth, backlash-free motion over a 51 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. 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. 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-UMR8.51精密双列滚珠轴承公制线性级具有高稳定性和刚性的钢结构特点。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。UMR8系列级有双列滚珠轴承，是承受高达900牛的高负载的理想选择。移动的轴承由两个弹簧预加载，以确保恒定的千分尺接触，在51毫米的行程范围内平稳、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。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叠在XY配置和安装到一个表或面包板。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。
