About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40B
The AirTAC B01-SDA40X40B is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) line, meaning it is mechanically identical to the base SDA40X40B. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, operating within a 0.15-1.0 MPa pressure range.
This unit features a male M14x1.5 piston rod thread for robust load coupling and uses a PT1/8 port. Its short riveted body minimizes axial mounting depth compared to round-body alternatives. End-stops rely on a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40B Is Used
PCB Router Z-Axis
Drives the vertical plunge of a PCB depaneling router. The 628.3 N push force at 0.5 MPa securely holds the spindle carriage, while the male M14x1.5 rod end firmly mounts the motor bracket.
Carton Flap Folder
Folds major flaps on a continuous carton sealing line. The compact riveted body saves axial depth on the narrow machine frame, and the fixed NBR bumper absorbs the repetitive end-stop impact.
Stamping Press Ejector
Pushes formed metal parts out of a progressive die. Operating at 30-500 mm/s, it cycles rapidly to clear the die bed before the next strip feed, requiring an external shock absorber for high-energy stops.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40B the Right Cylinder?
When sizing this 40mm bore, stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For this specific model, the safe working load is approximately 377 N (about 60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. To order, confirm the 40mm bore, 40mm stroke, PT1/8 port, male M14x1.5 rod thread, and no magnet. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock. An external rod lock or pilot-operated check valve is required to hold a load safely.
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-SDA40X40B FAQ
This double-acting 40mm bore cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, and 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the standard SDA40X40B, with identical mechanical specifications. This specific SKU lacks the -S option, so it has no piston magnet and cannot accept reed or electronic switches. It uses a fixed NBR bumper at each end instead of an adjustable air cushion.
