Name: Festo 537128 Compact cylinder ADNGF-40
Brand: Festo

Compact cylinder ADNGF-40

The Festo 40 mm piston diameter industrial component operates as a double-acting unit based on ISO 21287 with a stroke range of 5 mm to 300 mm and an operating pressure of 0.1 MPa to 1 MPa (1 bar to 10 bar). Its structural design incorporates a piston, piston rod, profile barrel, and a guide rod with a yoke for protection against torsion, featuring elastic cushioning rings/pads at both ends alongside self-adjusting pneumatic end-position cushioning and position sensing via proximity switch. Certified for explosive atmospheres with ATEX and UKCA markings covering Zone 1, Zone 2, Zone 21, and Zone 22, it carries II 2G and II 2D categories with Ex h IIC T4 Gb and Ex h IIIC T120°C Db ignition protection types for an ambient temperature range of -20°C to +60°C. Available variants include EX protection approval, stroke adjustment advancing, low friction, a through, hollow piston rod, and a temperature range of 0 to +150°C for any mounting position.

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.
