The AirTAC AirTAC SDA40X110BH 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 SDA40X110BH is a double-acting single-rod compact cylinder engineered with a 40 mm bore and 110 mm stroke. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. This specific SKU includes a male M14x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance. The hard-anodized bore and two-way piston seal ensure reliable service within the 30-500 mm/s speed range.
Designed to minimize axial mounting depth, the riveted body saves valuable machine footprint compared to conventional round-body units. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each stroke end to decelerate the load. Because this configuration omits the -S magnet option, it cannot directly host AirTAC reed or electronic switches. Furthermore, the end bumper decelerates motion but does not function as a lock; an external rod lock or pilot-operated check valve is necessary to hold a load safely without live pressure.

Pushes cartons onto secondary sorting lanes within high-speed distribution hubs, utilizing the 110 mm stroke to clear adjacent belt traffic.
Strikes molded plastic components out of warm tooling cavities, where the FKM seals withstand elevated ambient heat and residual lubricants.
Tucks corrugated box flaps prior to case sealing machinery, taking advantage of the male M14x1.5 thread for rigid flap-finger attachments.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. The 628.3 N output at 0.5 MPa translates to a safe working load of roughly 377 N (about 60 percent capacity) or a vertical lift capability near 32 kg with a 2:1 safety factor. To order correctly, confirm the 40 mm bore, 110 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the FKM seal specification.
Remember that a standard compact cylinder drifts when air pressure is lost or the directional valve is centered. The fixed NBR bumper only absorbs impact energy near the stroke limits and provides no braking function. If your mechanism must maintain position during an emergency stop or pressure drop, integrate an external locking device.
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 force is 128 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU lacks the internal piston magnet, so it cannot host reed or electronic switches. You must select an SDA40 variant with the -S option for position sensing capabilities.
