Festo
8041856
Belt driven linear actuator ELGA-TB-KF-70-1000-0H
The Festo 8041856 is an electromechanical linear axis with a toothed belt featuring a size 70 structure, a 1000 mm working stroke, and a 28.65 mm drive pinion effective diameter. This unit integrates a recirculating ball bearing guide, an incremental linear potentiometer measuring principle, and compatibility with stepper or servo motors delivering a maximum driving torque of 5.02 Nm, a top speed of 5 m/s, and an acceleration up to 50 m/s² with a repetition accuracy of ±0.08 mm. Operating reliably across an ambient temperature range of -10 °C to 60 °C at a 100% duty cycle, the assembly is housed in an IP40-rated enclosure conforming to VDMA24364 Zone III LABS standards and features 2nd moments of area Iy of 146050 mm⁴ and Iz of 459290 mm⁴.
