About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20S
The AirTAC B01-SDA25X20S is a double-acting single-rod compact cylinder. The B01- prefix designates an application-dedicated (customer-specified) variant, mechanically identical to the standard SDA25X20S. It provides 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. A built-in piston magnet allows position detection via AirTAC reed or electronic switches fitted into the body grooves.
The short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion. Buyers should note that this cylinder does not hold position on air loss—the piston drifts—so an external rod lock or pilot-operated check valve is required for suspended loads.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20S Is Used
PCB Depaneling Router
Actuates the cutting tool feed on an electronics assembly line, utilizing the 20 mm stroke and 245.4 N push force for precise board separation.
Carton Flap Folder
Folds minor corrugated box flaps prior to tape sealing, where the compact riveted body minimizes axial length inside tight packaging machine frames.
Bottle Sorting Diverter
Pushes beverage containers into adjacent lanes using the built-in S magnet and electronic switches to confirm the 20 mm retraction stroke.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X20S the Right Cylinder?
When sizing this 25 mm bore, step down to the SDA20 which yields 157.1 N push at 0.5 MPa, or step up to the SDA32 providing 402.1 N push at 0.5 MPa. The computed safe working load is roughly 147 N (about 60 percent of the 245.4 N figure), translating to a vertical lift capacity near 12.5 kg with a 2:1 safety margin. To order, confirm the 20 mm stroke, M5x0.8 port, female M5x0.8 rod thread, and the S magnet option.
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-SDA25X20S FAQ
This 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, or 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa with a speed range of 30-500 mm/s.
The B01- prefix marks an application-dedicated (customer-specified) variant of the SDA25X20S, meaning it shares the exact same physical specs. It uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high energy impacts, add an external shock absorber.
