The AirTAC AirTAC SDA12X50SB Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 50mm 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 SDA12X50SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly yields a very short axial length, saving mounting depth where standard round bodies fail to fit. Operating at 0.15-1.0 MPa, it generates 56.5 N of push force and 42.4 N of pull force at 0.5 MPa.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -B option provides a male M5x0.8 threaded piston rod end, offering a straightforward mechanical coupling for your payload. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion.

Drives small suction nozzles to lift and position delicate printed circuit boards during surface mount assembly using its 56.5 N push capacity.
Moves a micro-pump head for precise chemical reagent dispensing, where the 50 mm stroke and compact 12 mm body conserve valuable benchtop space.
Pushes lightweight plastic components out of an injection mold cavity, utilizing the male M5x0.8 rod thread to secure a custom soft-tip ejector pin.
When sizing this 12 mm bore actuator, sizing both ways is critical. If you need more force, stepping up to the SDA16 increases the 0.5 MPa push output to 100.5 N. If your payload is lighter, this SDA12X50SB provides a safe working load of roughly 34 N (about 60% of its 56.5 N capacity) and can vertically lift approximately 2.9 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm stroke, M5x0.8 air port, male M5x0.8 rod thread, and the required magnetic sensor option. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting 12 mm bore cylinder provides a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push force is 79.2 N. The theoretical maximum push force is 12 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.
It includes a built-in magnet (-S) compatible with AirTAC reed or electronic switches, but it does not have adjustable air cushions. Instead, a fixed NBR bumper at each end absorbs the end-stop impact. For high-speed operations, you should slow the approach or add an external shock absorber.
