The AirTAC SDA16X45B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 45mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA16X45B is a double-acting single-rod compact cylinder delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, making it highly effective for tight machine footprints. The unit operates at speeds between 30 and 500 mm/s.
This specific SKU features a male M5x0.8 threaded piston rod for direct load coupling, replacing the standard female M3x0.5 thread. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches.

Uses the 45 mm stroke and 100.5 N push force to eject separated circuit boards from a routing fixture without occupying excessive vertical space.
Folds lightweight cardboard flaps on a packaging line, utilizing the male M5x0.8 rod end for direct mounting of a custom folding arm.
Moves a dosing needle into position for reagent dispensing, where the short riveted body minimizes overall instrument width.
When sizing this 16 mm bore unit, consider stepping down to the SDA12, which provides 56.5 N of push at 0.5 MPa, or moving up to the SDA20, which yields 157.1 N at the same pressure. To finalize your order, confirm the 16 mm bore, 45 mm stroke, M5x0.8 air port, male rod thread, and the absence of a piston magnet.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 100.5 N of push force and 86.4 N of pull force. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot host reed or electronic switches. You would need the -S variant for sensing. Additionally, this unit uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion.
