Name: Festo 576129 Stopper cylinder DFSP-40-20-F-PA
Brand: Festo

Stopper cylinder DFSP-40-20-F-PA

The Festo 576129 is a double-acting industrial component featuring a 40 mm piston diameter, a 20 mm stroke, and elastic cushioning rings at both ends for position damping. Configured for pulling operation with an internal M8 piston rod thread and a round piston rod, it operates within a pressure range of 0.12 MPa to 1 MPa utilizing compressed air conforming to ISO 8573-1:2010 [7:4:4]. This unit achieves ISO 14644-1 Class 5 cleanroom suitability, exhibits a CRC 2 moderate corrosion resistance class, and functions across an ambient temperature range of -10 °C to 80 °C while withstanding a permissible impact force of 5540 N on the advanced piston rod.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
