About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20SB
The AirTAC B01-SDA40X20SB is a double-acting, single-rod compact cylinder engineered for tight axial spaces. The leading "B01-" prefix designates this as an application-dedicated (customer-specified) variant of the standard SDA40X20SB, meaning it is mechanically identical to the base model while grouping specific customer builds into a dedicated line. Delivering 628.3 N of push force at 0.5 MPa, it uses a hard-anodized bore and a two-way piston seal for reliable pneumatic performance.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male-thread piston rod (-B) sized at M14x1.5 for secure mechanical load coupling. End-of-travel impact is managed by a fixed NBR bumper that decelerates the piston, which is not an adjustable air cushion. Operating between 0.15 and 1.0 MPa, the unit provides a safe working load of roughly 377 N (about 60% of its 0.5 MPa output) and a vertical lift capacity near 32 kg with a 2:1 safety margin.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20SB Is Used
CNC Fixture Clamping
Secures aluminum workpieces in a CNC machining center using its 628.3 N extend force, while the 20mm stroke minimizes the overall fixture footprint.
Carton Flap Folding
Drives short-stroke folding arms on a packaging line, utilizing the male M14x1.5 rod end for rigid linkage attachment and the built-in magnet for position verification.
Sorter Diverter Gate
Actuates a routing diverter on a package conveyor, where the compact riveted body fits within the narrow 40mm side-frame clearance.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20SB the Right Cylinder?
When sizing this 40mm bore actuator, evaluate your force requirements carefully. Stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, whereas stepping up to the SDA50 increases that output to 981.7 N. To order this exact configuration, confirm the 40mm bore, 20mm stroke, PT1/8 port, built-in magnet (S), and male M14x1.5 rod thread (B). Note that a plain compact cylinder does not hold its position if air pressure drops or the valve centers; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the load. For vertical or suspended loads requiring fail-safe holding, an external rod lock or pilot-operated check valve is necessary.
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-SDA40X20SB FAQ
This 40mm bore double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. Its theoretical maximum push is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and it operates at speeds between 30 and 500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the SDA40X20SB; it shares the exact same physical specs, seals, and dimensions as the base model. It does not have an adjustable air cushion. Instead, it relies on a fixed NBR bumper at each end to decelerate the stroke. For high-speed or high-energy cycles, you should add an external shock absorber or slow the pneumatic approach.
