Festo has introduced its newest generation of Cartesian handling system mechanical axes: ELGD-TB tooth belt actuators and ELGD-BS ball screw actuators. These actuators feature bearings inlaid into the aluminum extrusion and extended bearings to the full width of the axis. The low-profile ELGD is 30% lighter than larger units while its rigidity and guide load capacity are similar. The ELGD-BS ball screw drive offers configurable stroke lengths up to 8.2 ft. The ELGD-TB toothed belt drive provides stroke lengths of up to 27.9 ft. The ELGD series gives a choice of carriage options, including a long carriage and additional passive carriage. The long carriage integrates a second pair of split ball bearing cartridges, while the passive second carriage allows the loads on the guidance to be distributed even further. The ELGD features a stainless-steel cover strip, minimizing particle emissions.
