The AirTAC AirTAC SDA16X45SN Compact Cylinder | 16mm Bore 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.
The AirTAC SDA16X45SN is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It delivers 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. The short riveted body drastically reduces axial mounting depth compared to conventional round-body units, making it ideal for space-constrained assemblies.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s, and the M5x0.8 port ensures efficient airflow for this 16 mm bore class.

Provides the 100.5 N extension needed to press and stabilize printed circuit boards during automated router depaneling without consuming excessive Z-axis height.
Actuates the upper heated platen on small pharmaceutical blister sealing machines, utilizing the 45 mm stroke and fixed NBR bumpers to ensure consistent contact pressure.
Drives precision needle valves in automated liquid handling systems, where the built-in magnet confirms valve seat position via a reed or electronic switch.
When sizing this 16 mm bore actuator, evaluate your force needs bidirectionally: stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. For the SDA16X45SN, a safe working load is approximately 60 N (about 60% of its 100.5 N capacity), translating to a vertical lift of roughly 5.1 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 16 mm bore, 45 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the required magnetic switch. Note that a plain compact cylinder drifts when air is lost or a valve is centered—the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely.
Quick checklist
This 16 mm bore double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa. Its theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-energy cycles, slow the approach or add external shock absorption. The included -S magnet allows direct mounting of AirTAC reed or electronic switches in the body grooves for position confirmation.
