The unit consists of a stationary base with a load-bearing carriage that travels along a customextruded wear-resistant aluminum rail. The system uses either a Size 17 hybrid external linear actuator or a Size 17 hybrid double-stack external linear actuator integrated into the slide for a complete single-axis positioning system. The system can come with various leads and shaft-end configurations to accommodate any source of rotary power. The system offers control of slide bearing play with a self-adjusting linear bearing. Full-length slots are accommodated using integrated T-slots. Four or six screws attach loads to the compact moving carriage. For applications requiring extreme control, the unit can be used with high-precision antibacklash nuts.
