High performance cantilever axes with spindle drives are ideal for handling applications that demand fast and precise positioning.

This open platform design allows OEMs and system integrators to use either a Festo servo or stepper motor, or the motor and controller of their choice. The EGSA is compatible with Festo’s modular handling and assembly range, can be used in any orientation - including vertical - and can handle high levels of torsional load. It is ideal for precision short-stroke Z axis functions involving fast positioning, such as those used in palletising systems, 2D and 3D gantry robots, and pick & place units.

Key facts:
• 50 mm and 60 mm wide models.
• 100, 200 and 300 mm stroke lengths
• Speeds up to 1.5 m/s
• Loads up to 6 kg
• Peak thrust up to 200 N
• Acceleration rates as high as 25 m/s2
• Repeatable positioning to within ±20 microns

Compatible with servo & stepper drives
The EGSA series cantilever axes are suitable for use with standard stepper or servo motors and controllers, which can be Festo or third-party products. Festo offers a range of compatible couplings, coupling houses and motor flanges for inline axial mounting - all of which are available separately or as complete, single part number kits - as well as a belt transmission unit which enables a servo motor to be installed in parallel with the axis.

Free specification software proposes solutions according to application parameters
Engineers will find that choosing the most appropriate EGSA series cantilever axis and associated component parts for their particular application couldn’t be easier; Festo’s latest Positioning Drives software - guides you through every aspect of selection and can even create a complete bill of materials.

Quick and easy commissioning with free software
Commissioning an EGSA series cantilever axis is equally simple; Festo includes a copy of its renowned FCT commissioning software with every axis. This intuitive Windows-based software can be used offline or online, and allows the physical and electrical characteristics of all drive-related functions - including the controller, motor and positioning axis - to be correlated and checked for compatibility and performance. The software also enables engineers to verify motion control programs in advance of system commissioning - it automatically warns of any impermissible programmed values, without requiring the electronics hardware to be connected.

Robust, long life for a variety of applications
Festo’s EGSA series cantilever axes are expressly designed for ease of installation and a long, trouble-free service life. The axes incorporate centring ring technology to facilitate precise alignment, and are lubricated for life. They are copper and Teflon free (CT) - making them suitable for use in LCD and plasma screen manufacturing processes - conform to the RoHS requirements of EU Directive 2002/95/EC, and meet the clean room 1000 standard.
