About the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20S
The AirTAC B01-SDA32X20S is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated customer-specified variant, mechanically identical to the standard SDA32X20S. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. The short riveted body significantly reduces axial mounting depth where a round-body unit will not fit.
This 32mm bore model features a 12mm piston rod and PT1/8 ports. Because this SKU includes the S option, it has a built-in piston magnet for position sensing using an AirTAC reed or electronic switch fitted into the body grooves. End stops rely on a fixed NBR bumper which decelerates the piston near stroke end but is not an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20S Is Used
PCB Routing Machine
Drives a short 20mm stroke cutting head across printed circuit boards, utilizing the compact riveted body to minimize Z-axis footprint.
Carton Flap Folder
Actuates a folding arm to close corrugated box flaps, using the 402.1 N push force to overcome light cardboard resistance.
Sheet Metal Ejector
Pushes stamped parts out of a press die area, relying on the built-in S magnet to trigger an electronic switch for part confirmation.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20S the Right Cylinder?
When sizing this unit, step down to the SDA25 which provides 245.4 N push at 0.5 MPa, or step up to the SDA40 which yields 628.3 N push at 0.5 MPa. For this 32mm bore, the safe working load is approximately 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. To order, confirm the 32mm bore, 20mm stroke, PT1/8 port, S magnet option, and female M6x1.0 rod thread.
A plain compact cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift and the fixed bumper only decelerates it near the end of travel. If your application must hold a load without live pressure, install an external rod lock or a pilot-operated check valve.
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-SDA32X20S FAQ
At 0.5 MPa this 32mm bore cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
The B01- prefix denotes an application-dedicated customer-specified variant of the SDA32X20S, sharing the exact same physical specifications. It does not have an adjustable air cushion; instead it uses a fixed NBR bumper at each end to decelerate the stroke. For high energy loads, add an external shock absorber.
