The M-MVN120 Precision Ball Bearing Vertical Linear Stage provides precise 20 mm manual height control with micron-scale sensitivity. Its high load capacity makes it especially suited to vertical positioning of heavy payloads. The stage utilizes an inclined plane design consisting of two precision-machined, opposing wedge blocks. Horizontal translation of the lower wedge is transformed into vertical motion of the upper wedge by means of inclined ball races. For linear, backlash-free travel, ball races are fabricated from precision-ground tool steel and are pre-loaded by a spring. A rotation of one division on the micrometer scale corresponds to a vertical displacement of half the linear displacement distance, thereby doubling the sensitivity. Manual positioning sensitivity can be approximately 500 nm using the BM25.40 micrometer. This stage has a large mounting platform that incorporates an array of tapped metric mounting holes for the convenient attachment of components.


M-MVN120精密滚珠轴承垂直直线台，提供20毫米精确手动高度控制，具有微米级灵敏度。它的高负载能力使其特别适合于重型载荷的垂直定位。工作台采用倾斜平面设计，由两个精密加工的、相对的楔块组成。下楔体的水平位移通过斜球滚道转化为上楔体的垂直运动。对于直线、无后摆行程，滚珠滚道由精磨工具钢制造，并由弹簧预压。在千分尺上每分之一的旋转相当于线性位移距离的一半的垂直位移，因此灵敏度加倍。使用BM25.40千分尺，手动定位灵敏度可以达到大约500纳米。这个阶段有一个大的安装平台，它包含一系列抽头的公制安装孔，方便组件的连接。
