About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X100SB
The AirTAC B01-SDA25X100SB is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA25X100SB, meaning it is mechanically identical to the standard model but grouped for specific use cases. It delivers 245.4 N of push force at 0.5 MPa and utilizes a 10 mm piston rod. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, freeing up valuable machine footprint.
This specific SKU includes the S option (built-in piston magnet for AirTAC reed or electronic switches) and the B option (a male M8x1.25 threaded rod end for secure load coupling). Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Operating speeds span 30-500 mm/s, and the hard-anodized bore ensures durable, low-friction operation.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X100SB Is Used
PCB Handling Ejection
Pushes populated circuit boards out of an SMT pick-and-place line using the male M8 rod end, relying on the compact body to fit within tight conveyor clearances.
Carton Flap Folding
Extends 100 mm to tuck minor flaps on packaging lines, where the 245.4 N force is ample and the built-in magnet confirms extension via a reed or electronic switch.
Lab Dispenser Positioning
Moves a fluid dispensing head over multi-well plates, taking advantage of the 30-500 mm/s speed range and the short overall length to minimize frame bulk.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X100SB the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA20 bore provides 157.1 N of push at 0.5 MPa, whereas stepping up to the SDA32 yields 402.1 N. This 25 mm bore generates a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. Ensure you specify the 100 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the required magnetic sensor when ordering.
Keep in mind that a standard compact actuator cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than acting as a lock. If your application demands position holding without live pressure, you must integrate 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-SDA25X100SB FAQ
This 25 mm bore cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. The 100 mm stroke falls within the 130 mm maximum standard stroke limit for this bore size.
The B01- prefix simply designates an application-dedicated (customer-specified) grouping of the standard SDA25X100SB; the physical specs remain identical. It does not have adjustable air cushions; instead, a fixed NBR bumper absorbs impact at the stroke ends, so for high-energy cycles you should add an external shock absorber or slow the approach speed.
