Festo
556811
Ball screw axis EGC-185- -BS-KF
The Festo 556811 is an electromechanical linear axis featuring a ball screw structural design with a size 185, a 40 mm screw diameter, and a 40 mm/U spindle pitch supporting a working stroke from 50 mm to 3000 mm in any mounting position. Integrated with a recirculating ball bearing guide, this unit delivers a maximum speed of 2 m/s, a maximum acceleration of 15 m/s², a repetition accuracy of ±0.02 mm, and a maximum force Fy of 15200 N under a 100% duty cycle. Operating within a temperature range of -10 °C to 60 °C, the assembly achieves an IP40 protection rating, VDMA24364-B2-L LABS conformity, and incorporates an incremental linear potentiometer measuring principle alongside compatibility with stepper and servo motors.

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.
