The AirTAC AirTAC SDA16X25BH 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 SDA16X25BH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly shortens axial mounting depth compared to round-body units, yielding a theoretical push of 100.5 N and pull of 86.4 N at 0.5 MPa. This specific SKU features a male M5x0.8 piston rod thread for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized to reduce friction and extend cycle life. End-stop deceleration is handled solely by a fixed NBR bumper, meaning there is no field-adjustable air cushion; for high kinetic energy loads, an external shock absorber is advised. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Provides the 100.5 N extend force required to push singulated circuit boards out of a routing fixture, where the short 25mm stroke and FKM seals resist ambient flux fumes.
Actuates a small heated platen in a pharmaceutical packaging line; the male M5 rod threads directly into the tooling plate and the compact body saves vertical space.
Cycles a precision needle valve for 2-part epoxy metering, using the fixed NBR bumper to soften the 25mm stroke end without needing external cushions.
When sizing this 16mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the 0.5 MPa push capacity to 56.5 N, whereas stepping up to the SDA20 increases it to 157.1 N. For the SDA16X25BH specifically, the safe working load is approximately 60 N (about 60% of the 100.5 N figure), which translates to a vertical lift capacity near 5.1 kg when applying a 2:1 safety factor. Confirm your ordering essentials: 16mm bore, 25mm stroke, M5x0.8 port, male M5x0.8 rod thread, and FKM seals. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; if your process demands strict position holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16mm bore double-acting cylinder generates a push of 100.5 N and a pull of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger reed or electronic switches. If your application requires position feedback, you must select the -S variant. Additionally, the male M5x0.8 rod end and fixed NBR bumpers mean there is no adjustable air cushion, so high-speed approaches should be slowed externally.
