About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X25SB
The AirTAC B01-SDA25X25SB is a double-acting, single-rod compact cylinder generating 245.4 N of push force at 0.5 MPa. The leading B01- prefix designates this as an application-dedicated (customer-specified) variant of the standard SDA25X25SB, meaning it is mechanically identical to the base model but grouped for specific industry builds. Its short riveted body minimizes axial mounting depth, saving valuable machine footprint where a standard round-body unit would not fit.
This specific configuration includes an integrated piston magnet (S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-threaded M8x1.25 piston rod end (B) for secure mechanical coupling to your load. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits rather than utilizing an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X25SB Is Used
PCB Routing Fixture
Secures printed circuit boards during routing operations, utilizing the 245.4 N push force to clamp panels firmly while the short 25 mm stroke maintains a minimal machine profile.
Carton Flap Folding
Actuates folding mechanisms on packaging lines to tuck carton flaps, where the male M8x1.25 rod end provides a robust mounting point for the folding arm.
Sorting Diverter Gate
Drives a lightweight diverter arm to route small parcels on a conveyor belt, relying on the integrated magnet to trigger AirTAC reed or electronic switches for position confirmation.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X25SB the Right Cylinder?
When sizing this unit, evaluate your force needs bidirectionally: 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. For the 25 mm bore at 0.5 MPa, the safe working load is approximately 147 N (about 60 percent of the 245.4 N figure), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 25 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the built-in magnet.
Keep in mind that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end without acting as a lock. If your application must hold a load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-SDA Dedicated Cylinder B01-SDA25X25SB FAQ
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, it yields 343.6 N push and 288.6 N pull. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a speed of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) line of the base SDA25X25SB, sharing identical mechanical specifications. It does not have adjustable air cushions; instead, a fixed NBR bumper at each end absorbs the end-stop impact. For high-speed or high-energy cycles, add an external shock absorber or slow the approach speed.
