About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X30
The AirTAC B01-SDA25X30 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA25X30, meaning it is mechanically identical to the standard model but grouped for specific customer builds. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa, operating within a 0.15-1.0 MPa pressure range.
Its short riveted body drastically reduces axial mounting depth compared to round-body units, saving valuable machine footprint. The bore is hard-anodized and uses a two-way piston seal. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion, so high-speed cycles may need external shock absorbers. This specific SKU lacks the S option, so it has no piston magnet and cannot host reed or electronic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X30 Is Used
PCB Drill Press Indexing
Provides 245.4 N of extend force to position vertical drill spindles over printed circuit boards, utilizing the 30 mm stroke for precise Z-axis depth control.
Carton Flap Folding
Drives mechanical fingers to fold corrugated box flaps prior to taping, where the compact riveted body minimizes interference on tight packaging conveyor lines.
Sheet Metal Alignment Stops
Acts as an adjustable physical stop to register aluminum sheets on a cutting table, handling the 12.5 kg vertical load capacity with a 2:1 safety margin.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X30 the Right Cylinder?
When sizing this 25 mm bore, step down to the SDA20 which provides 157.1 N push at 0.5 MPa, or step up to the SDA32 which yields 402.1 N push at 0.5 MPa. Based on the 245.4 N output at 0.5 MPa, the safe working load is roughly 147 N (about 60 percent capacity), translating to a vertical lift capability of approximately 12.5 kg with a 2:1 safety margin. To order, confirm the 25 mm bore, 30 mm stroke, M5x0.8 port, female rod-end thread (M5x0.8), and no magnet. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and does not function as a lock or brake. To hold a vertical load securely without live pressure, an external rod lock or pilot-operated check valve is required.
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-SDA25X30 FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, the push force is 343.6 N and the pull force is 288.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The B01- prefix simply designates this as an application-dedicated (customer-specified) variant of the SDA25X30; mechanically, it shares the exact same specs. This SKU does not have a piston magnet, so it cannot use reed or electronic switches. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion.
