Guide Mechanism Type
●Cross-Roller Bearing Guide
| The cross-roller guide is a limited stroke linear and bending guide that consists of a roller race and rollers. The roller race has 90 degree V-shape surface and it is harden and precisely polished. It is not only had a polished precise surface but also precisely correct 90 degree. The cylindrical shaped rollers are inserted between two roller races and they are aligned alternately. When the stage is moved, these rollers are rolling smoothly at the same time with the same tension because the gap between roller race is correctly arranged and maintained for the same distance. There is no slipping, no stopping due to the effective contact. As one of the feature, it has highly rigid more than ball guide because it has a longer contact line. |  |
●Gothic Arc
| Gothic arc is guide mechanism that is consist from the pseudo-cylindrical sliding surface and the ball (see fig-2). This sliding surface is processed into both of table and base of the stage, and finish in quench and grind. The ball is set between groove of sliding surface. The sliding surface touch the ball in each 4 point, then this point contact mechanism not likely to bring up differential slip. And the size of ball is used for pressurizing control, it bring decreasing of parts number. |  |
Standard & Mirror Symmetry , Vertical Configurations
Micrometer and clamp position can be customized to meet specific application requirements at no additional cost. The bracket type vertical linear stage (-X1 type) has an X-axis stage customized to a stand type. |
Vertical (Z-type) Configuration Typically, to suppress any influence from the stage top face, the feed mechanism is mounted on the base of stage. If the stand type is used with this mounting configuration, a load is applied along the spring extension of the stage and the stage may drop due to gravity (as shown in the left part in the right figure). Bracket type vertical linear stage may solve this problem by changing the position of micrometer holder.(see the right part in the right figure). |
