The AirTAC SDA16X20N Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 20mm 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 SDA16X20N is a double-acting, single-rod compact cylinder engineered for tight machinery spaces.
Its riveted body assembly drastically reduces axial mounting depth compared to round-body units. The bore is hard-anodized for durability, while a fixed NBR bumper at each end absorbs end-stop impact. This specific SKU lacks a piston magnet, so it cannot host magnetic switches; order an -S variant if reed or electronic sensing is required.

Positions delicate printed circuit boards on an SMT line using its 100.5 N push force without overwhelming fragile fiberglass substrates.
Maintains precise tracking on horizontal flow-wrap machines where the short 16 mm bore footprint prevents interference with moving film rollers.
When sizing this 16 mm bore unit, consider stepping down to the SDA12 if your load requires only 56.5 N of push at 0.5 MPa, or move up to the SDA20 which provides 157.1 N if greater thrust is needed. To order correctly, confirm the 16 mm bore, 20 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and no magnet.
Keep in mind 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. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa this cylinder provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 121 N pull. The theoretical maximum push force is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include a piston magnet, meaning it cannot host reed or electronic switches. You must select an SDA16 model with the -S option code to enable magnetic sensing in the body grooves.
