The AirTAC AirTAC SDA25X5B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 5mm 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 SDA25X5B is a double-acting, single-rod compact cylinder engineered for extremely short axial mounting envelopes. A riveted unibody architecture integrates the barrel, rear cover, piston, and rod to minimize footprint where a conventional round-body actuator cannot fit. Delivering 245.4 N of push force at 0.5 MPa, this 25 mm bore unit is built for tight, high-cycle clamping duties.
This specific SKU features a male M8x1.25 piston rod thread for robust mechanical coupling to your load. The bore inner wall is hard-anodized for low-friction longevity, while a fixed NBR bumper at each end decelerates the piston near the stroke limits. Note that this configuration omits the piston magnet, so position sensing is not supported without the -S option. Operating speed ranges from 30-500 mm/s.

Secures delicate printed circuit boards during pick-and-place assembly, utilizing the 5 mm stroke and 245.4 N force to grip without crushing components.
Drives the short 5 mm closing motion of heated sealing jaws in vertical form-fill-seal machinery, fitting neatly into narrow frame gaps.
Acts as a hard stop for thin sheet metal feeding into a press, where the male M8x1.25 rod end provides a durable, threaded contact point.
When sizing this actuator, evaluate your force requirements bidirectionally. Stepping down, the SDA20 provides 157.1 N of push at 0.5 MPa; stepping up, the SDA32 yields 402.1 N at the same pressure. For the SDA25X5B, a safe working load is approximately 147 N (about 60% of the 245.4 N capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 5 mm stroke, M5x0.8 air port, male M8x1.25 rod end (B), and no sensor magnet.
Remember that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the end-of-stroke impact rather than locking the load. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
At 0.5 MPa, this 25 mm bore cylinder provides 245.4 N of push force and 206.2 N of pull force. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger reed or electronic switches. You must select the -S option code to enable sensing. Additionally, the end-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
