LINEAR AXIS WITH DIRECT LINEAR ACTUATION
Schunk Inc. has introduced a series linear axis, LIRAX-M LD, designed for assembly automation and for handling weights up to 20 kg. The unit is constructed out of an aluminum profile that has integrated roller guides and is actuated by a linear motor. The profile provides a standard stroke length of up to 2 m.
LIRAX-M-LD axis modules are available in two different designs.
The user can choose between a signal-drive slide with feed forces of 50 N (11 lbf) to 300 N (68 lbf), or a twin-drive slide which will double the feed force to 100 N and 600 N correspondingly. With the linear motor and roller guides, the LIRAX-M-LD provides for impressive acceleration of 70 m/s2, which is 7x the acceleration of gravity and speeds of up to 5 m/s. With this high acceleration and speed, the axis is able to hold a repeat accuracy of √Ç¬±0.01 mm.
