The AirTAC AirTAC SDA25X120N Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 120mm 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 SDA25X120N is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It delivers a 245.4 N push force at 0.5 MPa, yielding a safe working load of roughly 147 N or a 12.5 kg vertical lift with a 2:1 margin. The riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce overall length compared to round-body units.
This 25 mm bore unit features a 10 mm piston rod and an M5x0.8 port. It relies on a fixed NBR bumper at each end to decelerate the stroke end, rather than an adjustable air cushion. Because this specific SKU lacks the -S option, it has no piston magnet and cannot support magnetic switches.

Pushes small cartons off a packaging line conveyor using its 245.4 N thrust at 0.5 MPa within a minimal mounting footprint.
Secures delicate printed circuit boards during automated soldering or inspection without overwhelming the 10 mm rod.
Extends 120 mm to eject lightweight plastic component trays from storage racks in automated retrieval systems.
When sizing this actuator, consider stepping down to the SDA20, which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32, which offers 402.1 N at the same pressure. To order correctly, confirm the 25 mm bore, 120 mm stroke, M5x0.8 port, female rod-end thread, and the absence of a sensor magnet. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a lock or brake. To hold a vertical load securely without live pressure, you must add an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push is 343.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must specify the -S option code when ordering. Additionally, this model uses fixed NBR bumpers for end-stop deceleration, which are not adjustable air cushions.
