The AirTAC AirTAC SDA12X35SB Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 35mm 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 SDA12X35SB is a double-acting single-rod compact cylinder engineered for tight machinery footprints. It generates 56.5 N of push force and 42.4 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to traditional round-body units, making it ideal for confined spaces. The unit includes a built-in piston magnet for position sensing.
This specific configuration features a 6 mm piston rod with a male M5x0.8 thread end for direct load coupling, alongside an M5x0.8 air port. The bore is hard-anodized for longevity, and end-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speed ranges from 30-500 mm/s.

Drives small vertical pickers in electronics assembly lines, utilizing the 56.5 N push force to seat lightweight connectors onto printed circuit boards.
Moves precision metering valves in automated fluid dispensing equipment where the 35 mm stroke and short body length minimize machine envelope.
Pushes miniature plastic components out of molding fixtures, using the male M5x0.8 threaded rod to securely attach a custom ejector pin.
When sizing this 12 mm bore actuator, consider stepping up to the SDA16, which provides 100.5 N of push force at 0.5 MPa if your application requires more power. As the smallest bore in the series, this model offers a highly compact footprint but yields a safe working load of roughly 34 N (about 60% of its 56.5 N capacity), allowing a vertical lift of approximately 2.9 kg with a 2:1 safety margin. Ensure you specify the 35 mm stroke, M5x0.8 port, male M5 rod thread (B), and the integrated magnet (S) when ordering. Note that a standard cylinder drifts if air pressure is lost; use an external rod lock or pilot-operated check valve if the load must be held.
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. Operating pressure is 0.15-1.0 MPa and speed is 30-500 mm/s.
End-of-stroke deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion, so you may need an external shock absorber for high-energy impacts. Additionally, the piston will drift if air is lost; a pilot-operated check valve or external rod lock is required to hold a load.
