The AirTAC AirTAC SDA40X160 Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 160mm 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 SDA40X160 is a double-acting single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth compared to conventional round-body designs. This specific configuration features a 160 mm stroke and a 16 mm piston rod.
Because the 160 mm stroke exceeds the 130 mm maximum standard stroke for this 40 mm bore, this unit is classified as non-standard and produced as a made-to-order item. The bore is hard-anodized and uses a two-way piston seal, while end-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. This SKU does not include a piston magnet, meaning it cannot support magnetic sensing without upgrading to the -S variant.

Pushes parcels off a sorting line using the 628.3 N extend force, though the 160 mm stroke requires verifying lateral space to avoid rod buckling.
Folds corrugated cardboard flaps during box assembly, relying on the 527.8 N retract force to cycle quickly within the 30-500 mm/s speed range.
Maintains yarn tension dynamics by extending a guide bar, benefiting from the hard-anodized bore for continuous high-cycle operation.
When sizing this model, consider stepping down to the SDA32 bore, which provides 402.1 N of push force at 0.5 MPa, or moving up to the SDA50 bore, which yields 981.7 N at the same pressure. For the SDA40X160, the safe working load is approximately 377 N (about 60% of the 628.3 N figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder cannot hold a load if air pressure is lost or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. For applications requiring suspended load holding, an external rod lock or pilot-operated check valve is necessary. To order, confirm the 40 mm bore, 160 mm non-standard stroke, PT1/8 port, female rod-end thread (M8x1.25), and the absence of a sensor magnet.
Quick checklist
This 40 mm bore cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the built-in piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option code when ordering to enable sensor groove functionality.
