Airtac SDA Ultra Thin Cylinder SDA16X25
The AirTAC SDA Ultra Thin Cylinder SDA16X25 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.

About the Airtac SDA Ultra Thin Cylinder SDA16X25
The AirTAC SDA16X25 is a double-acting single-rod compact cylinder engineered for tight spaces, delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for dense machinery layouts. The unit features a hard-anodized bore and a two-way piston seal for reliable operation.
This specific configuration uses an M5x0.8 air port and a 6 mm piston rod with a female M3x0.5 thread end. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-speed cycling. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA16X25 Is Used
PCB Routing Head
Drives a light routing spindle on an electronics assembly line, utilizing the 25 mm stroke to lower and lift the cutting tool precisely.
Small Part Diverter
Pushes miniature plastic housings off a packaging conveyor, leveraging the 100.5 N extend force to clear parts reliably.
Lab Dispenser Actuation
Moves a metering valve for chemical dosing in automated lab equipment where the short riveted body minimizes overall machine footprint.
Is the Airtac SDA Ultra Thin Cylinder SDA16X25 the Right Cylinder?
When sizing this 16 mm bore actuator, consider stepping down to the SDA12 which provides 56.5 N of push at 0.5 MPa for lighter duties, or stepping up to the SDA20 which yields 157.1 N if your load requires more force. To finalize your order, confirm the 16 mm bore, 25 mm stroke, M5x0.8 port, female rod thread, and the absence of a sensor magnet. Note that a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates the stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA16X25 FAQ
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Additionally, because this SKU does not include the -S magnet option, it cannot support AirTAC reed or electronic switches. You would need the SDA16X25S variant for position sensing.
