About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X30
The AirTAC B01-SDA20X30 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA20X30, meaning it is mechanically identical to the standard line but grouped for specific customer builds. It generates 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint.
This 20mm bore unit features an 8mm piston rod and an M5x0.8 air port. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so for high-energy cycles you should slow the approach or add an external shock absorber. Because this specific SKU lacks the -S option, it has no piston magnet and cannot accept magnetic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X30 Is Used
PCB Depaneling Router
Actuates the tooling carriage on a depaneling machine, utilizing the 30mm stroke and 157.1 N force to precisely separate routed circuit boards.
Carton Flap Folder
Folds minor flaps on small packaging lines, where the compact riveted body minimizes axial intrusion into tight conveyor framing.
Lab Dispenser Positioning
Moves a metering valve into position over vials, lifting an 8 kg fixture with a 2:1 safety margin before the fluid dispense cycle begins.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X30 the Right Cylinder?
When sizing this actuator, step down to the SDA16 which provides 100.5 N of push at 0.5 MPa, or step up to the SDA25 which yields 245.4 N at the same pressure. A practical safe working load is roughly 94 N (about 60 percent of the 157.1 N figure), allowing a vertical lift of approximately 8 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 20mm bore, 30mm stroke, M5x0.8 port, female M4x0.7 rod thread, and note that no magnet is present. Remember that a plain compact cylinder drifts if air pressure is lost; the fixed bumper only decelerates near stroke end and does not lock the load, so employ an external rod lock or pilot-operated check valve if position holding 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-SDA20X30 FAQ
At 0.5 MPa this 20mm bore cylinder provides 157.1 N push and 131.9 N pull. At 0.7 MPa it provides 219.9 N push and 184.7 N pull. The theoretical maximum push is 32 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 denotes an application-dedicated (customer-specified) build of the standard SDA20X30; the physical specs, seals and dimensions remain exactly identical. Regarding end-stop behavior, it uses a fixed NBR bumper to decelerate the piston, not an adjustable air cushion. For high-speed applications you should externally slow the approach or add a shock absorber.
