The AirTAC AirTAC SDA12X5BH Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 5mm 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 SDA12X5BH is a double-acting single-rod compact cylinder engineered for extremely tight axial spaces. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit drastically reduces mounting depth compared to conventional round-body designs. It delivers a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa, yielding a safe working load of roughly 34 N or a 2.9 kg vertical lift with a 2:1 margin.
This specific configuration includes a male M5x0.8 threaded piston rod for direct load coupling and an FKM fluororubber seal for enhanced thermal and oil resistance. The 12 mm bore features an M5x0.8 port and a 6 mm rod. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. Note that without the -S option, this SKU lacks a piston magnet and cannot support position sensing.

Provides the precise 5 mm extension and 56.5 N force needed to press test probes onto populated circuit boards without damaging delicate traces.
Actuates micro-dispense valves for chemical reagents, leveraging the FKM seals to resist aggressive solvents and maintain accurate shot volumes.
Pushes small plastic or metal parts out of machining fixtures, using the compact 6 mm rod and male M5 thread to fit within dense tooling grids.
When sizing this 12 mm bore actuator, stepping up to the SDA16 increases your 0.5 MPa push force to 100.5 N, whereas the SDA12 represents the smallest available option in the series. To verify your order, confirm the 12 mm bore, 5 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and FKM seal. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only slows the piston near the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 12 mm bore cylinder generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, push is 79.2 N and pull is 59.4 N. The theoretical maximum push is 12 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. If you require position sensing, you must select the -S variant. Additionally, this version uses a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion, and the male M5x0.8 rod thread allows for direct mechanical mounting.
