About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X15
The AirTAC B01-SDA20X15 is a double-acting, single-rod compact air cylinder engineered for tight axial spaces. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA20X15, meaning it is mechanically identical to the base model but grouped for specific customer builds. It provides a push force of 157.1 N and a pull force of 131.9 N at 0.5 MPa, operating within a speed range of 30-500 mm/s.
This 20 mm bore unit features a hard-anodized inner wall and a fixed NBR bumper at each end to decelerate the stroke end. Unlike an adjustable air cushion, this fixed rubber bumper cannot be tuned in the field, so high-speed approaches may require external shock absorption. The riveted body design significantly reduces overall mounting length compared to round-body cylinders, making it ideal for shallow machine footprints.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X15 Is Used
PCB Depaneling Ejector
Short 15 mm stroke pushes separated circuit boards out of a routing fixture, utilizing the 157.1 N extend force within a compact electronics assembly chassis.
Carton Flap Tucker
Tucks minor flaps on small pharmaceutical cartons before tape sealing, where the shallow 20 mm bore body fits neatly between guide rails without clashing.
Lab Dispenser Actuator
Drives a micro-pump head for precise fluid dispensing, taking advantage of the 8 mm rod diameter and consistent 131.9 N retract force at 0.5 MPa.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X15 the Right Cylinder?
When sizing this actuator, consider stepping up or down based on your force requirements. The SDA16 offers 100.5 N of push force at 0.5 MPa for lighter duties, while the SDA25 provides 245.4 N if your load demands more power. For this specific B01-SDA20X15 configuration, confirm the 20 mm bore, 15 mm stroke, M5x0.8 port, female M4x0.7 rod-end thread, and the absence of a piston magnet. A safe working load is approximately 94 N (about 60% of the 157.1 N figure), yielding a vertical lift capacity of roughly 8 kg with a 2:1 safety margin.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near the end without acting as a mechanical lock. If your application requires position holding without live pressure, you must integrate 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-SDA20X15 FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 131.9 N. At 0.7 MPa, the push force is 219.9 N. The theoretical maximum push force is 32 kgf at 1.0 MPa, which is the maximum operating pressure. The maximum standard stroke available for this 20 mm bore is 100 mm.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the SDA20X15, meaning the physical specifications, seals, and dimensions are identical to the standard model. This specific SKU does not include a piston magnet (no -S suffix), so it cannot accept AirTAC reed or electronic switches. You would need the -S variant for position sensing.
