Festo’s new ELGA-TB is the company’s next generation belt drive. In comparison to the series it replaces, the ELGA-TB features improvements in feed forces, payload, and list price. The ELGA-TB is available in three sizes and two styles of guides to accommodate a wide range of application requirements.
The ELGA-TB-RF uses roller bearing guides, making it the ideal rugged and built-to-last solution for dynamic, long-stroke applications where high speeds, feed forces, and accelerations are required. The ELGA-TB-G uses a plain bearing guide for applications with small or externally guided loads.
The ELGA-TB-RF is rated at speeds up to 33 feet/second (10 meters/second) and acceleration of up to 164 feet/second2 (50 meters/second2). The maintenance interval is rated at 393 million inches (10 million meters) traveled. Repeatability is rated at up to + .003 inches (+ 0.08 mm). Working stroke for the new series ranges from 1.97 inches to 28 feet (50 mm to 8.5 meters) with feed force ranges from 350 up to 1,300 N.
A corrosion resistant cover strip provides protection for belt and bearings in dirty environments. A magnetic attachment for the cover strip ensures protection when the belt drive is inverted. The new series also has flexible motor attachments; the motor can be mounted at four different positions and motor position can be changed at any time. The drive is compatible with all common stepper and servo motors.
Festo PositioningDrives sizing software helps users reliably select the right axis, while the Festo Configuration Tool ensures convenient and easy commissioning.
