The AirTAC AirTAC SDA40X110SB 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 SDA40X110SB 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 body design significantly reduces axial mounting depth compared to round-body alternatives, making it highly effective for machinery where space savings are critical. The unit includes a built-in piston magnet (-S) for position sensing and a male M14x1.5 thread (-B) on the 16 mm rod for direct load coupling.
This model operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because it lacks an adjustable air cushion, high-energy cycles may require an external shock absorber or a slowed approach. The hard-anodized 40 mm bore ensures durability, while the integrated sensor grooves readily accept AirTAC reed or electronic switches to track the 110 mm travel.

Drives routing flaps on high-speed logistics conveyors, utilizing the 110 mm stroke to shift parcels between sorting lanes without consuming excessive frame depth.
Executes side-flap folding on automated case erectors, where the 628.3 N push force easily overcomes cardboard resistance and the male M14x1.5 rod secures custom tooling.
Actuates the measuring probe arm in offline tool setting stations, benefiting from the hard-anodized bore and precise position detection via reed or electronic switches.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, whereas moving up to the SDA50 provides 981.7 N. For the SDA40X110SB, the 628.3 N output translates to a safe working load of roughly 377 N (about 60% capacity) and a vertical lift capability near 32 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and does not function as a locking brake. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 40 mm bore, 110 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the required magnetic sensor.
Quick checklist
This double-acting 40 mm bore cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, and 879.6 N push at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and has a speed range of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed applications, you should add an external shock absorber. Additionally, it does not hold its load when air is lost—the piston will drift, so an external rod lock or pilot-operated check valve is required for position holding.
