The AirTAC AirTAC SDA16X80 Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 80mm 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 SDA16X80 is a double-acting, single-rod compact cylinder engineered to deliver 100.5 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial footprint, conserving machine depth where conventional round bodies fail. This specific 80 mm stroke configuration exceeds the 60 mm standard limit for a 16 mm bore, making it a non-standard, made-to-order item.
The bore features a hard-anodized inner wall and a two-way piston seal, while end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot host reed or electronic switches. Operating pressure spans 0.15-1.0 MPa, and the 6 mm piston rod uses an M5x0.8 port alongside a female M3x0.5 rod-end thread.

Uses the 100.5 N extend force to push singulated circuit boards out of a routing fixture, where the short riveted body keeps the conveyor frame shallow.
Closes light cardboard flaps on a packaging line; the fixed NBR bumper absorbs the end impact without needing field adjustment.
Drives a 80 mm stroke to lower a pipette head into test tubes, requiring an external shock absorber if cycled at the upper 500 mm/s speed limit.
When sizing this unit, consider stepping down to the SDA12, which yields 56.5 N of push at 0.5 MPa, or moving up to the SDA20, which provides 157.1 N. For this 16 mm bore, a 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. Confirm your ordering essentials: 16 mm bore, 80 mm non-standard stroke, M5x0.8 port, female rod thread, and no sensor magnet.
Remember that a standard compact body does not hold its load if air pressure drops or the valve centers; the piston will drift. The fixed NBR bumper only decelerates the stroke near its limits and acts as neither a lock nor a brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa. The theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
An 80 mm stroke exceeds the 60 mm maximum standard stroke for a 16 mm bore, so it is manufactured as a non-standard, made-to-order item. End positioning uses a fixed NBR bumper to decelerate the piston, which is not an adjustable air cushion.
