Miniature Positioning Tables RT-...-SRM

Manual driven 25 - 150 mm

PM's lead screw tables series RT-..-SRM are miniature cross roller translation tables for manual operation. The tables provide accurate positioning capability and extremely smooth running operation along a linear axis. A positive position locking device eliminates drift when idle. RT-SRM slides are equipped with crossed roller ways achieving high load carry capacity and stiffness with very smooth motion.
