Festo
8041851
Belt driven linear actuator ELGA-TB-KF-70-300-0H
This Festo electromechanical linear axis features a size 70 structural design with an integrated toothed belt, a 28.65 mm drive pinion effective diameter, a 3 mm toothed belt pitch, a 300 mm working stroke, and a 0 mm stroke reserve. Equipped with a recirculating ball bearing guide and an incremental linear potentiometer measuring principle, it accommodates stepper or servo motors, achieves a max. driving torque of 5.02 Nm, a max. acceleration of 50 m/s², a max. speed of 5 m/s, and a repetition accuracy of ±0.08 mm. The unit operates at a 100% duty cycle within an ambient temperature range of -10 °C to 60 °C, maintains IP40 protection, complies with VDMA24364 Zone III LABS conformity, and provides a 2nd moment of area Iy of 146050 mm⁴ and Iz of 459290 mm⁴ in any mounting position.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
