About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X100S
The AirTAC B01-SDA20X100S is a double-acting single-rod compact cylinder. The leading B01- prefix designates an application-dedicated (customer-specified) variant of the base SDA20X100S, meaning it is mechanically identical to the standard model but grouped for specific customer builds. It yields 157.1 N of push force and 131.9 N of pull force at 0.5 MPa.
The riveted body design minimizes axial mounting depth, saving valuable machine footprint where a round-body unit will not fit. This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End stopping relies on a fixed NBR bumper, which decelerates the piston near stroke end rather than acting as a lock or adjustable cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X100S Is Used
PCB Depaneling Router
Actuates the cutting head feed on an automated PCB depaneling machine, utilizing the 100mm stroke to clear the work area for tool changes.
Package Sorting Diverter
Pushes small parcels off a sorting line where the 157.1 N extend force at 0.5 MPa is sufficient to redirect light cardboard boxes.
Lab Sample Dispenser
Drives a pipetting head in a clinical diagnostic analyzer, using the -S magnet to trigger reed or electronic switches for precise fluid draw positioning.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X100S the Right Cylinder?
When sizing this 20mm bore, step down to the SDA16 which provides 100.5 N of push at 0.5 MPa, or step up to the SDA25 which offers 245.4 N at 0.5 MPa. For this 100mm stroke configuration, the safe working load is approximately 94 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 8 kg with a 2:1 safety margin. Confirm your ordering essentials: 20mm bore, 100mm stroke, M5x0.8 port, female M4x0.7 rod thread, and the included sensor magnet. Because a plain cylinder drifts when air is lost or the valve is centered, holding a load without live pressure 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-SDA20X100S FAQ
This 20mm bore cylinder generates 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 0.15-1.0 MPa with a speed range of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the standard SDA20X100S, with no mechanical changes to the bore, stroke, or seals. It does not have an adjustable air cushion; instead, a fixed NBR bumper at each end absorbs the stroke end impact. For high-speed cycles, slow the approach or add an external shock absorber.
