The AirTAC AirTAC SDA40X110H Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 110mm 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 SDA40X110H is a double-acting single-rod compact cylinder engineered for tight axial mounting spaces. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. This specific SKU utilizes a fluororubber (FKM) seal for enhanced thermal stability and oil resistance. A 16 mm piston rod mates via an M8x1.25 female thread, operating through a hard-anodized bore fed by PT1/8 ports.
The short riveted body minimizes machine footprint compared to conventional round-body units. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing.

Secures aluminum engine blocks during CNC milling, utilizing the 628.3 N extend force and FKM seals to withstand cutting fluid exposure.
Drives the mechanical arms that tuck corrugated box flaps prior to hot-melt sealing, where the 110 mm stroke provides full reach across the packaging line.
Actuates a routing flap to push selected wooden pallets off a high-speed logistics belt, taking advantage of the short body depth to fit within the conveyor frame.
When sizing this actuator, evaluate your neighbors: the SDA32 provides 402.1 N of push at 0.5 MPa for lighter duties, while the SDA50 steps up to 981.7 N for heavier loads. At 0.5 MPa, this 40 mm bore yields a safe working load around 377 N (roughly 60% capacity) and can vertically lift approximately 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 110 mm stroke, PT1/8 port, female rod thread, and FKM seals. Remember that a standard compact unit drifts when air pressure is lost or the valve centers; maintaining a vertical load requires an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 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. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot support reed or electronic switches. You would need to specify the -S option to enable magnetic sensing. Additionally, end-stops rely on a fixed NBR bumper, not an adjustable air cushion, so external shock absorbers are recommended for high-speed operations.
