Festo
556812
Belt driven linear actuator EGC-50- -TB-KF
The Festo 556812 is an electromechanical linear axis featuring a toothed belt with a 2 mm pitch, an 18.46 mm drive pinion effective diameter, and a size 50 structural design with a recirculating ball bearing guide. This component delivers a working stroke between 50 mm and 1900 mm, a max speed of 3 m/s, a max acceleration of 50 m/s2, and a repetition accuracy of ±0.08 mm for a 100% duty cycle with either a stepper or servo motor in any mounting position. Certified for Zone 1, Zone 2, and Zone 21 explosive environments under ATEX, UKEX, and EPL Gb/Db standards with Ex h IIC T4 Gb gas ignition protection, it operates within an ambient temperature range of -10°C to +60°C and conforms to VDMA24364 Zone III LABS (PWIS) requirements.

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.
