Festo
8041839
Ball screw axis ELGA-BS-KF-120-400-0H-10P-ML
The Festo 8041839 is an electromechanical linear axis featuring a ball screw structural design with a 400 mm working stroke, a size 120 profile, and a 25 mm screw diameter. Driven by a stepper or servo motor, this assembly delivers a spindle pitch of 10 mm/U, a maximum speed of 0.6 m/s, a maximum rotational speed of 3600 rpm, and a repetition accuracy of ±0.02 mm under a 100% duty cycle. Engineered with a recirculating ball bearing guide and an incremental linear potentiometer, the unit achieves a maximum acceleration of 15 m/s² within an ambient temperature range of -10 °C to 60 °C while maintaining IP40 protection and VDMA24364 Zone III LABS conformity 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.
