Linear Units with a rack drive

A Linear Unit with a rack drive is often the best solution when a powerful stroke and precise control are required. The driven gearwheel interlocks with the straight rack to eliminate the possibility of slip. The rotary motion of the drive motor is thus converted directly into the rectilinear motion of the carriage.
The rack drive is a robust linear drive that can be used to move heavy loads. A high standard of positioning accuracy is obtained, even on long axes, as the rack does not stretch out when under load.
