Semi-rotary actuator DRE-4-F04-Q08-FS

The Festo 189958 is a single-acting rack and pinion industrial component featuring a size 4 actuator, a 90-degree swivel angle, and an F04 flange hole pattern conforming to ISO 5211. Designed with a V11 shaft connection, G1/8 subbase pneumatic connection, and VDI/VDE 3845 NAMUR valve connection, this un-cushioned unit operates on compressed air from 2 to 10 bar while consuming 1.8 liters per cycle at 6 bar. It weighs 1,200 g, achieves a CRC 3 corrosion resistance classification, functions within an ambient temperature range of -20 to 80 °C in any assembly position, and closes via spring force.

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. 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.

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.
