About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20
The AirTAC B01-SDA40X20 is a double-acting, single-rod compact cylinder. The B01- prefix designates an application-dedicated (customer-specified) variant that is mechanically identical to the standard SDA40X20. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, utilizing a 16 mm piston rod and PT1/8 air port.
Its short riveted body drastically reduces axial mounting depth compared to round-body units, making it ideal for tight machine footprints. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. This specific SKU lacks a piston magnet, so it cannot host magnetic switches without upgrading to the -S option.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20 Is Used
CNC Fixture Clamping
Secures aluminum engine blocks onto machining centers. The 628.3 N extend force provides rigid holding against cutting forces without consuming valuable Z-axis envelope.
Carton Flap Folding
Drives mechanical arms to tuck corrugated box flaps prior to tape sealing. The 20 mm stroke executes rapid, repetitive motions within tight conveyor side frames.
Stamping Pin Ejection
Pushes small metal stampings out of progressive dies. The fixed NBR bumper absorbs the internal end-stop impact during fast 30-500 mm/s ejection cycles.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X20 the Right Cylinder?
When sizing this actuator, stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For the 40 mm bore, a safe working load is approximately 377 N (about 60% of the 628.3 N capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. To order, confirm the 40 mm bore, 20 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no magnet. Note that this unit will drift and cannot hold a load if air pressure is lost or the valve is centered; applying an external rod lock or pilot-operated check valve is required for 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-SDA40X20 FAQ
This 40 mm bore double-acting cylinder outputs 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum push of 128 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) build that is physically identical to the standard SDA40X20. It does not use adjustable air cushions; instead, a fixed NBR bumper decelerates the piston at stroke end. For high kinetic energy loads, you must externally slow the approach or add a shock absorber.
