Festo
556817
Belt driven linear actuator EGC-185- -TB-KF
The Festo 556817 is an electromechanical linear axis featuring a toothed belt with an 8 mm pitch, a drive pinion effective diameter of 73.85 mm, and a size 185 structural design with a recirculating ball bearing guide. This component supports a working stroke ranging from 50 mm to 8500 mm in any mounting position, driven by either a stepper or servo motor with an incremental linear potentiometer measuring principle. It delivers a maximum speed of 5 m/s, a maximum acceleration of 50 m/s², a repetition accuracy of ±0.1 mm, a 100% duty cycle, and maximum forces of 15200 N for both Fy and Fz. Operating within an ambient temperature range of -10 °C to 60 °C, the unit features an IP40 degree of protection, VDMA24364 Zone III LABS conformity, and 2nd moments of area Iy and Iz of 2340000000 mm⁴ and 2740000000 mm⁴, respectively.

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.
