Airtac B01-SDA Dedicated Cylinder B01-SDA32X20
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA32X20 is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20
The AirTAC B01-SDA32X20 is a double-acting, single-rod compact cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base SDA32X20, meaning it is mechanically identical to the standard model but grouped for specific customer builds. 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 merges the barrel, rear cover, piston, and rod to minimize axial mounting depth where a round-body unit will not fit.
This 32 mm bore unit features a 12 mm piston rod and PT1/8 ports. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion, so high-speed cycles may need an external shock absorber. Because this specific SKU lacks the -S option, it has no piston magnet and cannot host reed or electronic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20 Is Used
PCB Router Clamping
Secures printed circuit board panels during routing operations. The 20 mm stroke provides rapid clamping, while the compact depth keeps the fixture small.
Carton Flap Folding
Folds minor flaps on packaging lines ahead of case sealing. The 402.1 N push force easily overcomes cardboard resistance without stalling.
Stamping Pin Ejection
Ejects small stamped metal pins from a die. Operating at 30-500 mm/s, the unit cycles quickly to match press speed and clear the tooling.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA32X20 the Right Cylinder?
When sizing this model, compare its 402.1 N push at 0.5 MPa against adjacent bores: stepping down to the SDA25 yields 245.4 N, while stepping up to the SDA40 provides 628.3 N. A practical safe working load is roughly 241 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 20.5 kg with a 2:1 safety margin. To order, confirm the 32 mm bore, 20 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the absence of a magnet. Note that a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates near the end of travel and acts as neither a lock nor a brake, so holding a load requires an external rod lock or 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-SDA32X20 FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
The B01- prefix designates an application-dedicated (customer-specified) variant of the standard SDA32X20, sharing identical mechanical specs. This specific SKU lacks the -S option, meaning it has no piston magnet and cannot accept reed or electronic switches. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion.
