331 Series Stage

The 331 precision ball bearing translation stage offers exceptionally smooth linear travel. The time-tested design has been improved with the addition of more bearing area than similar stages. The increased bearing surface reduces non-linear motion when changing directions, and maximizes linearity towards the end of travel. The 331 has a side located non-influencing lock that is integrated with a graduated scale for position readout of 0.04 inches (1 mm). The actuator mounting block and stop block are designed to enable either right or left-hand mounting of the drive device. The actuator mounting block is compatible with our TPI series adjustment screws, 400 and 800 series actuators, as well as standard micrometers. The spring-loaded 331 stage is stackable for XY positioning requirements and is compatible with our MX-AB for Z-axis applications.
