The AirTAC AirTAC SDA40X110S 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 SDA40X110S is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly reduces overall length compared to round-body units, yielding a robust 628.3 N push force at 0.5 MPa. Equipped with a 16 mm piston rod and PT1/8 porting, it handles a 110 mm travel distance efficiently.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speed or add external shock absorbers for high-energy loads.

Actuates routing flaps on high-speed logistics conveyors, utilizing the 110 mm stroke to pivot packages into secondary sorting lanes smoothly.
Drives mechanical arms to fold corrugated box flaps prior to tape sealing, fitting easily into compact packaging line frames.
Raises and lowers physical stops to index wooden pallets at precise elevations for robotic layer stacking operations.
Selecting this 40 mm bore provides a safe working load around 377 N (roughly 60 percent of the 0.5 MPa push rating), translating to a vertical lift capacity near 32 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA32 yields 402.1 N at 0.5 MPa, while upgrading to the SDA50 offers 981.7 N for heavier demands. Confirm your ordering essentials: 40 mm bore, 110 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the integrated sensor magnet.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the directional valve centers. The fixed bumper only decelerates the piston near the stroke ends and does not function as a locking brake. To suspend a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, the fixed NBR bumper only decelerates the piston near the stroke end and is not a braking mechanism. The piston will drift if air pressure drops or the valve centers. You must add an external rod lock or pilot-operated check valve to maintain vertical position safely.
