The AirTAC AirTAC SDA16X45S 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 SDA16X45S is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It delivers 100.5 N of push force at 0.5 MPa, utilizing a hard-anodized bore and a two-way piston seal for reliable pneumatic performance. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives.
This specific configuration 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 cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. It features a 6 mm piston rod and an M5x0.8 port.

Drives short horizontal ejector strokes in electronic assembly lines, utilizing the 45 mm stroke and 100.5 N force to push components into carriers.
Actuates a small diverter flap on a packaging conveyor, where the compact riveted body minimizes axial footprint and the integrated magnet tracks flap position.
Applies controlled clamping pressure to small vials or test tubes in automated laboratory equipment, safely operating within the 86.4 N pull range at 0.5 MPa.
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 moving up to the SDA20 which yields 157.1 N if your application demands greater thrust. A practical safe working load for this model is approximately 60 N, equating to a vertical lift capacity of roughly 5.1 kg when applying a 2:1 safety margin. To finalize your order, confirm the 16 mm bore, 45 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the required magnetic sensor option. Note that a plain cylinder drifts when air pressure is lost; utilize an external rod lock or pilot-operated check valve if the load must be held securely.
Quick checklist
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 force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, end-of-travel deceleration relies solely on a fixed NBR bumper, not a field-adjustable air cushion; external shock absorbers are recommended for high speeds. This specific unit uses a female M3x0.5 rod-end thread on its 6 mm rod, and the -S designation indicates a built-in magnet for reed or electronic switches.
