The AirTAC AirTAC SDA16X20BH 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 SDA16X20BH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its short riveted body integrates the barrel, rear cover, and piston, drastically reducing axial mounting depth compared to round-body units. Delivering 100.5 N of push force at 0.5 MPa, it features a hard-anodized bore and a two-way piston seal for reliable pneumatic performance.
This specific configuration includes a male M5x0.8 threaded piston rod for secure mechanical coupling, alongside a fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this SKU lacks the -S magnet code, it cannot host AirTAC reed or electronic switches.

Actuates a routing tool guide with precise 20 mm strokes, utilizing the FKM seals to resist heat generated by high-speed cutting operations.
Pushes lightweight electronic components between conveyor lanes, where the short 16 mm bore body minimizes interference with adjacent transfer belts.
Applies 100.5 N of clamping force at 0.5 MPa to hold thin polymer films against heated sealing plates within a densely packaged assembly cell.
When sizing this 16 mm bore actuator, 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. Based on the 100.5 N output, the safe working load is approximately 60 N, translating to a vertical lift capacity of about 5.1 kg with a 2:1 safety margin. Ensure your ordering essentials capture the 16 mm bore, 20 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and FKM seals.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the load near the stroke end without acting as a mechanical lock. If your application requires static load holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 16 mm bore cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and sustains speeds of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, meaning it cannot trigger AirTAC reed or electronic switches. Detection would require the SDA16X20BHS variant. Additionally, end stops rely on a fixed NBR bumper that decelerates the piston, which is not an adjustable air cushion.
