Festo
8041846
Ball screw axis ELGA-BS-KF-120-400-0H-25P-ML
The Festo 8041846 is an electromechanical linear axis featuring a ball screw structural design with a size 120 profile, a 400 mm working stroke, a 25 mm screw diameter, and a 25 mm/U spindle pitch. Integrated with a recirculating ball bearing guide, an incremental linear potentiometer measuring principle, and compatibility with both stepper and servo motors, this unit delivers a maximum speed of 1.5 m/s, a max acceleration of 15 m/s², a 3600 rpm max rotational speed, and a repetition accuracy of ±0.02 mm across a 100% duty cycle. Engineered for any mounting position, the assembly provides an IP40 degree of protection, a 1240000 mm⁴ 2nd moment of area Iy, VDMA24364 Zone III LABS conformity, and operates within an ambient temperature range of -10 °C to 60 °C with a 0 mm stroke reserve.

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.
