About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20
The AirTAC B01-SDA25X20 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA25X20, meaning it is mechanically identical to the base model while grouped for specific deployment scenarios. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa.
The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. It features a hard-anodized bore and a fixed NBR bumper at each end to decelerate the stroke. Because this specific SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing. The Ø10 mm piston rod uses an M5x0.8 female thread end.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20 Is Used
Carton Flap Folding
Drives the short folding arm on automated packaging lines to tuck corrugated carton flaps before tape sealing, utilizing the 20 mm stroke to stay within tight machine clearances.
Sorting Diverter Gate
Pivots a lightweight diverter block on a package routing conveyor, providing 245.4 N of extend force to push parcels into secondary lanes without occupying excessive frame depth.
PCB Test Fixture
Lowers a test probe head onto printed circuit boards in electronics manufacturing, applying a controlled contact force via the hard-anodized bore and fixed NBR bumper.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20 the Right Cylinder?
When sizing this actuator, evaluate your force needs carefully. Stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 yields 402.1 N. This B01-SDA25X20 offers a balanced 245.4 N, translating to a safe working load of roughly 147 N (about 60% of the 0.5 MPa figure) or a vertical lift capacity near 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 20 mm stroke, M5x0.8 port, female rod thread, and no sensor magnet. Note that a standard compact cylinder drifts if air pressure is lost; holding a suspended load requires an external rod lock or 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-SDA25X20 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 is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The B01- prefix designates an application-dedicated (customer-specified) variant of the SDA25X20, sharing the exact same physical specifications. It does not have an adjustable air cushion; instead, a fixed NBR bumper absorbs impact at the stroke ends. For high-energy cycles, add an external shock absorber or slow the approach speed.
