Festo has launched its new EGC-HD linear drive which is easy to install and enables machine builders and OEMs to make significant cost savings.
Made from aluminium, EGC-HD has rigidity and strength to support loads of up to 1,300kg and up to 1,450Nm torque. The EGC-HD is based on the technology of Festo’s EGC linear axis and is well suited for use when heavy loads have to be moved accurately, for example on palletising, transfer lines and pick and place applications.
The ECG-HD linear drive features two guide rails and is available with a toothed belt or a ball screw drive in three widths (125mm, 160mm and 220mm) giving stroke lengths of up to 5,000mm for the toothed belt version and 2,400mm for the ball screw option.
Previously, users would have to specify two separate axes, which would need to be carefully aligned, and would require a coupling shaft. However, now users can use one EGC-HD axis, which is quicker to install and there is no need for an additional coupling shaft.
The EGC-HD has been designed with high feed forces and speeds in mind. The belt drive version can move at velocities of up to 5m/s and has an accuracy of 100µm. The ball screw version can move at velocities of up to 1.5m/s with a high accuracy of 20µm. The ball screw version is available in a choice of pitches from 10mm to 25mm and features a ball screw support system, meaning the drive can operate at full rotational speed, regardless of the stroke length.
The axis has a flexible motor mounting and machine builders don’t need to specify the position of the motor at the ordering stage. The motor can be freely mounted on any of the four corners, and can be changed at any time.
The linear axis can be simply mounted from the back or sides with slot nuts and it has the option for over travel inductive sensors which are flush mounted.
