About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10B
The AirTAC B01-SDA20X10B is a double-acting single-rod compact cylinder delivering 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA20X10B, meaning it is mechanically identical to the base model but grouped for specific use cases. It features a 20mm bore, a 10mm stroke, and a male M6x1.0 piston rod thread (denoted by the B option) for secure load coupling.
This riveted-body design saves significant axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. The hard-anodized bore ensures durability, while a fixed NBR bumper at each end decelerates the piston near stroke limits. Note that this SKU lacks a piston magnet, so it cannot support magnetic position sensing without the -S option.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10B Is Used
PCB Ejector Pins
Provides short 10mm ejection strokes for printed circuit boards in pick-and-place machinery, utilizing the 157.1N push force to clear delicate components safely.
Film Feed Sealing
Actuates sealing jaws in vertical form-fill-seal equipment where the 8mm rod and male M6 thread secure cutting blades within a minimal axial envelope.
Small Part Sorting
Drives diverter gates in electronic component sorting lines, relying on the compact riveted body to fit multiple actuators tightly along the conveyor belt.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10B the Right Cylinder?
When sizing this 20mm bore actuator, step down to the SDA16 for 100.5 N push at 0.5 MPa, or step up to the SDA25 for 245.4 N push at 0.5 MPa. For this 20mm model, the safe working load is approximately 94 N (about 60% of the 157.1 N figure), allowing a vertical lift of roughly 8 kg with a 2:1 safety margin. Confirm your ordering essentials: 20mm bore, 10mm stroke, M5x0.8 port, male M6x1.0 rod thread, and no sensor magnet. Keep in mind that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the end of travel. Use an external rod lock or pilot-operated check valve if the application requires position holding.
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-SDA20X10B FAQ
This double-acting 20mm bore cylinder provides 157.1 N push and 131.9 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa. The theoretical maximum push force is 32 kgf at 1.0 MPa. It operates at speeds between 30 and 500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the SDA20X10B, sharing the exact same physical specs. It does not have adjustable air cushions; instead, a fixed NBR bumper at each end absorbs the end stop. For high-speed cycling, add an external shock absorber or slow the approach.
