The AirTAC AirTAC SDA12X45SB Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm 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 SDA12X45SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly yields an exceptionally short axial profile, outperforming conventional round bodies where depth is restricted. Operating at 0.15-1.0 MPa, it yields 56.5 N of push force at 0.5 MPa, making it suitable for light-duty positioning.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, fitting neatly into the body's peripheral grooves for precise end-of-stroke detection. The unit also features a male M5x0.8 threaded piston rod for direct load coupling. End-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.

Drives small electronic parts into printed circuit board sockets with 56.5 N push force, utilizing the 45 mm stroke to fit within dense pick-and-place machinery.
Actuates a tiny gate arm to route vials on diagnostic analyzers, where the male M5x0.8 rod threads directly into the diverter linkage for secure attachment.
Maintains precise alignment of thin packaging web by nudging a guide roller, capitalizing on the short riveted body to fit inside narrow film dispensing frames.
For sizing context, this 12 mm bore generates 56.5 N push at 0.5 MPa, offering a safe working load around 34 N and a vertical lift capacity of roughly 2.9 kg with a 2:1 safety margin. If your application requires slightly more thrust, stepping up to the SDA16 provides 100.5 N push at 0.5 MPa. When ordering, confirm the 45 mm stroke, M5x0.8 air port, male M5x0.8 rod end, and the integrated magnet. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only slows the stroke near its end and does not function as a locking brake. To suspend a load safely 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, 79.2 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum push of 12 kgf at 1.0 MPa.
No, end-of-travel deceleration relies solely on a fixed NBR bumper, which is not a field-adjustable air cushion. Additionally, the piston will drift if air is lost or the valve is centered; you must use an external rod lock or pilot-operated check valve to hold a load.
