The AirTAC AirTAC SDA25X30BH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm 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 SDA25X30BH is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force at 0.5 MPa. Its short, riveted body design significantly reduces axial mounting depth, making it the superior choice when machine footprint constraints exclude longer round-body units. This specific configuration includes a male M8x1.25 piston rod end for straightforward load coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
The bore features a hard-anodized inner wall and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the -S magnet, it cannot host reed or electronic switches. Operating at speeds between 30-500 mm/s, it provides a safe working load of roughly 147 N (about 60 percent of the 0.5 MPa push figure) and can vertically lift approximately 12.5 kg with a 2:1 safety margin.

Utilizes the 245.4 N extend force to align delicate printed circuit boards on an SMT pick-and-place conveyor, where the short 25 mm bore riveted body conserves critical Z-axis clearance.
Drives a mechanical arm to tuck corrugated box flaps prior to tape sealing, benefiting from the FKM seals that withstand oily cardboard dust and elevated ambient heat.
Pushes short aluminum profiles against a rigid stop for precise cut-off sawing, using the male M8x1.25 rod end to thread directly into the squaring fixture.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N, allowing you to tune your payload capacity precisely. To finalize your order, confirm the 25 mm bore, 30 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the FKM seal option. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and acts neither as a lock nor a brake. To maintain vertical position holding without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, push increases to 343.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S option to enable sensing. Additionally, end-stop deceleration is handled solely by a fixed NBR bumper, which is not an adjustable air cushion; for high-energy cycles, slow the approach or add an external shock absorber.
