The AirTAC AirTAC SDA25X80B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 80mm 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 SDA25X80B is a double-acting, single-rod compact cylinder engineered to deliver a 245.4 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly abbreviated unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too long. The bore is hard-anodized and relies on a two-way piston seal for reliable operation across a 30-500 mm/s speed range.
This specific SKU features a male M8x1.25 piston rod thread, providing a robust external coupling point for your load. It is important to note this variant lacks a piston magnet, so it cannot host AirTAC reed or electronic switches. End-of-stroke deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Actuates a routing flap on a logistics sorting line, utilizing the 80 mm stroke and 245.4 N push force to redirect medium-weight parcels at high speeds.
Drives the mechanical arm that folds corrugated box flaps prior to tape sealing, where the short riveted body conserves valuable space on a compact packaging machine.
Pushes prepared test tubes or vials out of a centrifuge carousel, taking advantage of the male M8x1.25 rod end to securely thread on a custom non-marring ejector tip.
Selecting this 25 mm bore actuator involves sizing both ways: stepping down to the SDA20 yields 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. The 245.4 N output at 0.5 MPa translates to a safe working load of roughly 147 N (about 60 percent capacity) or a vertical lift capability of approximately 12.5 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the NBR bumper only decelerates the stroke end rather than locking the piston. For suspended loads, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 80 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the absence of a sensor magnet.
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 force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, meaning it cannot support AirTAC reed or electronic switches. You would need the SDA25X80BS variant for position sensing. Additionally, it uses fixed NBR bumpers for end-of-stroke deceleration rather than an adjustable air cushion.
