About the Airtac B01-SDA Dedicated Cylinder B01-SDA12X25B
The AirTAC B01-SDA12X25B is a double-acting, single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the standard SDA12X25B, meaning it is mechanically identical to the base model. It generates a 56.5 N push force at 0.5 MPa, utilizing a hard-anodized 12 mm bore and a two-way piston seal for efficient pneumatic actuation.
This unit features a male M5x0.8 threaded piston rod end (denoted by the B option) for direct load coupling, replacing the default female M3x0.5 thread. Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. The stroke end is decelerated by a fixed NBR bumper rather than an adjustable cushion, and because this specific SKU lacks the S magnet option, it cannot host magnetic position switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA12X25B Is Used
Lab Automation Handlers
Ideal for driving small sample grippers in analytical instruments where axial space is severely restricted and a 56.5 N extend force is sufficient.
PCB Populating Heads
Provides compact vertical positioning for pick-and-place nozzles, using the male M5x0.8 rod thread to mount delicate vacuum pickups securely.
Micro-Pouch Sealing
Actuates lightweight sealing jaws on small-format packaging lines, relying on the fixed NBR bumper to absorb the impact at the end of the 25 mm stroke.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA12X25B the Right Cylinder?
When sizing this actuator, consider stepping up to the SDA16 if your application requires more force, as the 16 mm bore provides a 100.5 N push at 0.5 MPa compared to this 12 mm bore's 56.5 N. As the smallest available bore in the series, there is no smaller standard SDA option to step down to. A practical safe working load is approximately 34 N (about 60% of the 0.5 MPa figure), which equates to a vertical lift capacity of roughly 2.9 kg when using a 2:1 safety margin.
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 the stroke end rather than locking it. For applications requiring suspended load holding, an external rod lock or pilot-operated check valve is necessary. To order, confirm the 12 mm bore, 25 mm stroke, M5x0.8 port, and the male M5x0.8 rod thread.
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-SDA12X25B FAQ
This 12 mm bore double-acting cylinder provides a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push force is 79.2 N and the pull force is 59.4 N. The theoretical maximum push force is 12 kgf at 1.0 MPa.
The B01- prefix indicates this is an application-dedicated, customer-specified variant of the SDA12X25B, with no mechanical changes to the core specs. The B suffix means the 6 mm piston rod features a male M5x0.8 thread end instead of the standard female M3x0.5 thread. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion.
