The AirTAC AirTAC SDA16X55BH Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 55mm 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 SDA16X55BH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted body assembly minimizes axial mounting depth, outperforming conventional round-body units where space is strictly limited. Delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa, it handles light-duty positioning with a 6 mm piston rod.
This specific SKU includes a male M5x0.8 threaded rod end for direct load coupling and utilizes high-temperature fluororubber (FKM) seals. The bore features a hard-anodized inner wall and a two-way piston seal. End-stopping is managed by a fixed NBR bumper that decelerates the piston near stroke completion rather than acting as a lock. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Acts as a compact routing head actuator in PCB depaneling machines, using its 55 mm stroke and 100.5 N push force to plunge cutting tools precisely.
Drives the sealing jaw in small-scale blister packaging equipment, where the FKM seals withstand elevated ambient temperatures and the short body saves axial depth.
Toggles a precision dispensing valve for laboratory fluid metering, offering a safe working load near 60 N to puncture and seal viscous chemical cartridges.
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. At 0.5 MPa, the safe working load is approximately 60 N (about 60% of the 100.5 N figure), translating to a vertical lift capacity near 5.1 kg with a 2:1 safety margin. To finalize your order, confirm the 16 mm bore, 55 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the FKM seal option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift and the fixed bumper only decelerates it near the stroke end. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore double-acting cylinder provides 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 within a pressure range of 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot trigger AirTAC reed or electronic switches. Additionally, end-of-stroke deceleration relies solely on a fixed NBR bumper, which is not an adjustable air cushion; for high-energy cycles, slow the approach or add an external shock absorber.
