Festo
8161441
Guided drive DFM-40-25-B-PPV-A-KF
The Festo 8161441 is a double-acting industrial drive unit featuring a 40 mm piston diameter, a 25 mm stroke, and a yoke operating mode with recirculating ball bearing guidance. It incorporates adjustable pneumatic cushioning at both ends, accommodates position sensing via a proximity switch, and operates within a pressure range of 0.15 MPa to 1 MPa using compressed air conforming to ISO 8573-1:2010 [7:4:4]. This structural guide unit delivers a theoretical retracting force of 686 N and an advancing force of 754 N at 6 bar, while satisfying ISO 14644-1 Class 6 cleanroom suitability and VDMA24364-B1/B2-L LABS conformity.

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.
