The AirTAC AirTAC SDA12X50B 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 SDA12X50B is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, the overall axial length is drastically reduced compared to round-body alternatives. Delivering 56.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 50 mm stroke.
This specific SKU features a male M5x0.8 threaded piston rod for straightforward load coupling, overriding the default female M3x0.5 thread. The 12 mm bore utilizes an M5x0.8 port and relies on a fixed NBR bumper at each end to decelerate the stroke end—this is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot support AirTAC reed or electronic switches.

Drives delicate test probes against printed circuit boards, where the 56.5 N push force at 0.5 MPa is sufficient for contact without damaging the substrate.
Indexes a 50 mm stroke to trigger micro-fluidic valve dispensers in analytical instruments, taking advantage of the minimal axial mounting depth.
Pushes lightweight plastic components out of pick-and-place nests using the male M5x0.8 rod end to attach a custom soft-tip ejector finger.
When sizing this 12 mm bore actuator, evaluate your force margins carefully. At 0.5 MPa, this model provides 56.5 N of push force, yielding a safe working load of roughly 34 N (about 60 percent of capacity) and a vertical lift capability of approximately 2.9 kg with a 2:1 safety margin. If your application requires slightly more thrust, stepping up to the SDA16 increases the push force to 100.5 N at 0.5 MPa. As the smallest bore in the SDA series, there is no smaller standard option available.
For ordering and integration, confirm the essentials: a 12 mm bore, 50 mm stroke, M5x0.8 port, and the -B male M5x0.8 rod thread. Keep in mind that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. If your application must maintain a load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 12 mm bore cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, and 79.2 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot support AirTAC reed or electronic switches. Additionally, it relies on a fixed NBR bumper to decelerate at stroke ends rather than an adjustable air cushion; for high-energy cycles, you should slow the approach or add an external shock absorber.
