Festo: Heavy-duty electric cylinder
Suitable for dynamic, high-feed-force applications, such as clamping, pressing, cable tensioning, and large component feeding, the ESBF cylinder from Festo is capable of generating almost two tons (17,000 N) of feed force, making it possible to use in place of a hydraulic cylinder.
The introduction of the ESBF also extends the company’s range of Festo electric cylinders beyond its DNCE electric cylinder range and provides a significant increase in maximum possible feed forces and speeds.
The ESBF electric cylinder is available in three sizes – 63, 80, and 100 mm – with three ball-screw pitches/size.
Additionally, the ESBF electric cylinder offers flexibility. With the optional IP65 protection and bellows kit, the ESBF can be customized for a wide variety of environments, including those with high humidity, sawdust, metal chips, and more. The optional food-grade grease makes it possible to operate the ESBF above food zones with no concern for contamination. And the wide variety of mounting accessories simplifies design and saves time during installation.
For applications where space constraints may not allow the motor to be mounted axially, reverse parallel kits are available for the ESBF. If off-axis loading is required in an application, external guiding is offered as an accessory.
As with the DNCE electric cylinder range, the ESBF cylinder can be used with a variety of Festo motors and drives to meet the application requirements. Customers can use Festo’s free software, PositioningDrives, to easily select the correct ESBF, motor, and drive. The ESBF electric cylinder is easily commissioned using the Festo Configuration Tool (FCT) with a Festo motor and drive solution.
