The AirTAC AirTAC SDA25X110B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 110mm 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 SDA25X110B is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth, making it ideal for machinery where a standard round-body unit would be too bulky. The hard-anodized 25 mm bore operates efficiently between 30 and 500 mm/s.
This specific SKU features a male M8x1.25 threaded piston rod for direct load coupling, replacing the default female M5x0.8 end. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches. The piston relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion.

Ejects filled storage totes from a robotic pick station using the male M8x1.25 rod end to secure the pushing fixture.
When sizing this unit, consider stepping down to the SDA20, which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32, which yields 402.1 N. For this 25 mm bore, the safe working load is approximately 147 N (about 60% of the 245.4 N figure), allowing a vertical lift of roughly 12.5 kg with a 2:1 safety margin. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or pilot-operated check valve. To order, confirm the 25 mm bore, 110 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and no magnet.
Quick checklist
This double-acting 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push force is 50 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include the -S piston magnet, so it cannot host reed or electronic switches. You would need the -S variant for sensing. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
