About the Airtac B01-SDA Dedicated Cylinder B01-SDA12X45
The AirTAC B01-SDA12X45 is a double-acting single-rod compact cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA12X45, meaning it is mechanically identical to the base model. It provides 56.5 N of push force and 42.4 N of pull force at 0.5 MPa, utilizing a 12 mm bore and 45 mm stroke.
Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. The bore is hard-anodized, and deceleration at stroke ends is handled by a fixed NBR bumper rather than an adjustable cushion. This specific SKU lacks a piston magnet, so it cannot directly host magnetic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA12X45 Is Used
PCB Handling Ejectors
Uses the 56.5 N extend force to push bare boards out of testing fixtures without damaging delicate traces in SMT lines.
Lab Dispenser Positioning
Moves a fluid nozzle precisely over microplate wells where axial space is restricted, relying on the 45 mm stroke.
Small Part Ejection
Clears tiny plastic components from molding cavities, taking advantage of the compact 12 mm body footprint.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA12X45 the Right Cylinder?
When sizing this actuator, consider stepping up to the SDA16 if you need more power, as it provides 100.5 N of push at 0.5 MPa compared to this 12 mm bore's 56.5 N. Based on the 0.5 MPa push figure, the safe working load is approximately 34 N (about 60% of capacity), yielding a vertical lift capacity of roughly 2.9 kg with a 2:1 safety margin. Remember that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the end of travel. For secure load holding, an external rod lock or pilot-operated check valve is required. To order, confirm the 12 mm bore, 45 mm stroke, M5x0.8 port, female rod thread, and no magnet.
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-SDA12X45 FAQ
This 12 mm bore double-acting cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, and 79.2 N push at 0.7 MPa. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and has a speed range of 30-500 mm/s.
The B01- prefix simply denotes an application-dedicated (customer-specified) grouping of the standard SDA12X45; mechanically, it is identical to the base model. It uses a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. For high-speed applications, you should add an external shock absorber or slow the approach.
