The AirTAC AirTAC SDA40X5 Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 5mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X5 is a double-acting single-rod compact cylinder engineered for tight axial spaces. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, making it a robust choice for short-stroke actuation. The riveted body assembly significantly reduces overall mounting depth compared to conventional round-body cylinders, fitting neatly into cramped machine footprints.
This specific configuration features a 5 mm stroke, a 16 mm piston rod, and PT1/8 ports. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives a 16 mm rod to seat dowel pins into PCB fixtures, utilizing the 628.3 N push force within a shallow 5 mm stroke envelope.
Executes rapid 5 mm tucks on folding carton side flaps, where the compact riveted body minimizes interference with moving conveyor guides.
Ejects machined aluminum brackets from a CNC vice, relying on the fixed NBR bumper to absorb the sudden end-of-travel impact.
When sizing this unit, consider stepping down to the SDA32, which provides 402.1 N of push at 0.5 MPa, or moving up to the SDA50, which yields 981.7 N at the same pressure. At 0.5 MPa, the SDA40X5 offers a safe working load of roughly 377 N (about 60% of its rated push) and can vertically lift approximately 32 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load. To hold a position securely without live pressure, you must add an external rod lock or a pilot-operated check valve. When ordering, confirm the 40 mm bore, 5 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the absence of a piston magnet.
Quick checklist
The SDA40X5 delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum push of 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, tolerates temperatures from -20 to +70 C, and runs at speeds of 30-500 mm/s.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke end, which cannot be field-adjusted like an air cushion. Additionally, this specific SKU lacks the -S piston magnet, meaning it cannot support AirTAC reed or electronic switches without changing to the -S variant.
