The AirTAC AirTAC SDA25X75SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 75mm 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 SDA25X75SB is a double-acting single-rod compact cylinder engineered with a 25 mm bore and 75 mm stroke. It provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. The riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches via the body grooves. It is also equipped with a male-thread piston rod (-B) sized at M8x1.25 for secure mechanical load coupling. The unit relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion.

Actuates routing flaps on logistics sorting lines where the short riveted body minimizes protrusion into tight transfer zones.
Secures delicate circuit boards during drilling with a 245.4 N push force while the male M8x1.25 rod end firmly mounts custom tooling.
Drives mechanical folders on automated boxing machines, utilizing the 75 mm stroke and fixed NBR bumpers to absorb end-stop impact.
When sizing this 25 mm bore model, you can step down to the SDA20 which yields 157.1 N of push force at 0.5 MPa, or step up to the SDA32 which provides 402.1 N at the same pressure. This SDA25X75SB generates a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. Be aware that a plain compact cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a locking brake. If your application requires position holding without live pressure, an external rod lock or pilot-operated check valve is necessary. Confirm your ordering essentials: 25 mm bore, 75 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the integrated magnet.
Quick checklist
This double-acting cylinder delivers 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 force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. Additionally, it does not hold its load if air is lost, as the bumper is not a lock or brake. For load holding, an external rod lock or pilot-operated check valve is required.
