The AirTAC AirTAC SDA16X25SB Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 25mm 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 SDA16X25SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly yields a minimal axial length, delivering 100.5 N of push force at 0.5 MPa. This specific configuration includes a built-in piston magnet and a male M5x0.8 threaded rod end for straightforward load coupling.
The 16 mm bore features a hard-anodized inner wall and operates on filtered air at 30-500 mm/s. End-of-travel deceleration relies on fixed NBR bumpers rather than adjustable cushions, keeping the overall envelope short while absorbing routine impact energy.

Positions delicate printed circuit boards on an SMT line using the 25 mm stroke, where the short riveted body conserves valuable equipment bay depth.
Actuates a horizontal flow-wrap sealing head with 100.5 N of extend force, while the male M5x0.8 rod threads securely mount the sealing bar.
Ejects filled microplates from an automated analyzer using the integrated magnet to trigger a reed or electronic switch for precise cycle counting.
When sizing this 16 mm bore unit, consider stepping down to the SDA12 (56.5 N push @0.5 MPa) for lighter duties, or up to the SDA20 (157.1 N push @0.5 MPa) if your load requires more authority. For this SDA16X25SB configuration, verify your requirements for the 25 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the integrated sensor magnet. A practical safe working load is roughly 60 N (about 60% of the 100.5 N figure), allowing a vertical lift of approximately 5.1 kg with a 2:1 safety margin. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates 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, the push force is 100.5 N and the pull force is 86.4 N. At 0.7 MPa, the push force is 140.7 N and the pull force is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa.
It uses fixed NBR bumpers at each end to decelerate the piston; these are not adjustable air cushions. The cylinder does not hold its position if air is lost, as the bumper is not a brake. For load holding, an external rod lock or pilot-operated check valve is required.
