About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25S
The AirTAC B01-SDA20X25S is a double-acting single-rod compact cylinder. The leading B01- prefix denotes AirTAC's application-dedicated (customer-specified) line, meaning this unit is mechanically identical to the standard SDA20X25S. It provides 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, operating within a 30-500 mm/s speed range.
Its riveted body assembly significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. The bore is hard-anodized, and the integrated -S piston magnet allows position detection via an AirTAC reed or electronic switch fitted into the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25S Is Used
PCB Depaneling Router
Actuates a cutting head or support pin in compact electronics manufacturing equipment where the 25 mm stroke and 157.1 N force securely position small panels.
Carton Flap Folder
Folds minor flaps on small packaging lines, utilizing the short riveted body to fit within narrow conveyor side frames without exceeding the 8 kg vertical lift margin.
Lab Dispenser Head
Drives a precision fluid nozzle in analytical instruments, using the -S magnet to trigger an electronic switch for exact dosing cycles at up to 500 mm/s.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25S the Right Cylinder?
When sizing this 20 mm bore actuator, stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N. This B01-SDA20X25S configuration offers a safe working load around 94 N (roughly 60% of its 157.1 N capacity) and can vertically lift approximately 8 kg with a 2:1 safety margin. To order, confirm the 20 mm bore, 25 mm stroke, M5x0.8 port, built-in magnet, and female M4x0.7 rod thread. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end rather than locking the load, so add 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-SDA20X25S FAQ
The B01- prefix simply marks this as an application-dedicated variant of the SDA20X25S with identical mechanics. It generates 157.1 N push and 131.9 N pull at 0.5 MPa, 219.9 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. It features an 8 mm rod, an M5x0.8 port, and a maximum standard stroke of 100 mm.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high-speed approaches, you should add an external shock absorber. Additionally, it does not hold its load if air is lost; the bumper only softens the end stop, so an external rod lock is needed for secure position holding.
