The 423-MIC is a special bundle of three 423 Linear Stages included with all required SM-25 Micrometers. The model 423 translation stage with its large 3 in. square platform features exceptional performance, usability, and value with precision ball bearing construction – hardened balls rolling between opposing pairs of hardened and polished stainless steel rods providing better than 200 microradian angular deviation. For stability, repeatability, and exceptionally smooth motion, actuators bear upon a hardened carbide insert. Springs provide preload against the actuator tip to eliminate backlash. Although the stage is capable of traveling a full 1 in. (25.4 mm) with the SM-25 micrometer drive (included in bundle), the actuator mounting blocks can be relocated to accommodate 0.5 in. (12.7) drives like the SM-13. This stage can also be reconfigured into a left-handed version with the micrometer on the opposite side.
Ball bearings in these stages reduce friction compared with rolling motion to guide linear translation. Although the guide ways are externally loaded to eliminate unwanted runout in the bearings, friction remains negligible to provide smooth travel over the entire range. The motion of each axis can easily be locked in place.
These extended range stages are designed with symmetrical features allowing them to be reconfigured for left or right-handed operation. This video shows a 423 stage being reconfigured to have the micrometer accessible from the opposite side of the stage. This is needed to allow the stage to be used for vertical travel but is also useful for improving adjustment accessibility. Note, also, that the lock and the micrometer locations can be switched.
These extended range stages are designed to be easily configured into multi-axis stage stacks. An XYZ assembly is shown in this video using three SM-25 micrometer actuated 423 stages with a
Easily combine and stack these light-weight stages together with 481 Rotation Stages for a multi-axis system. The rotation stage may be mounted below or above the linear stages.
