Airtac SDA Ultra Thin Cylinder SDA16X45
The AirTAC Airtac SDA Ultra Thin Cylinder SDA16X45 is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 45mm 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 SDA16X45
The AirTAC SDA16X45 is a double-acting, single-rod compact cylinder engineered for tight machinery layouts. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa, operating at speeds between 30 and 500 mm/s. The hard-anodized 16 mm bore houses a two-way piston seal, while the short riveted body significantly reduces axial mounting depth compared to standard round-body units.
This specific configuration features a 45 mm stroke, a 6 mm piston rod, and an M5x0.8 air port. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. Because this SKU lacks the -S magnet option, it cannot host magnetic reed or electronic switches for position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA16X45 Is Used
PCB Depaneling Routing
Actuates a low-friction routing head in electronics assembly, using the 45 mm stroke to separate printed circuit boards without stressing adjacent components.
Blister Pack Sealing
Drives a small heated platen in medical packaging lines, applying up to 100.5 N of push force to seal thin polymer blister packs efficiently.
Lab Dispenser Actuation
Moves a precision metering valve for chemical reagents, relying on the compact riveted body to fit within crowded analytical instrument frames.
Is the Airtac SDA Ultra Thin Cylinder SDA16X45 the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the push output to 56.5 N at 0.5 MPa, whereas stepping up to the SDA20 increases it to 157.1 N. For the current 16 mm bore, the safe working load is approximately 60 N (about 60% of the 100.5 N figure), translating to a vertical lift capacity of roughly 5.1 kg with a 2:1 safety margin.
Remember that a basic compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. To maintain vertical position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 16 mm bore, 45 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and no sensor magnet.
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 SDA16X45 FAQ
This double-acting 16 mm bore cylinder provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push force is 140.7 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. The body does feature standard sensor grooves, but you must order the -S variant (e.g., SDA16X45S) to enable position sensing capabilities.
