About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25SB
The AirTAC B01-SDA40X25SB is a double-acting, single-rod compact cylinder engineered for space-constrained pneumatics. The "B01-" prefix designates this as an application-dedicated (customer-specified) variant of the base SDA40X25SB, meaning it is mechanically identical to the standard model but grouped for specific industry builds. It delivers a robust 628.3 N push force at 0.5 MPa alongside a 527.8 N pull force, operating efficiently at speeds between 30 and 500 mm/s.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It is configured with a male-thread piston rod (-B, M14x1.5) for secure mechanical load coupling. The hard-anodized bore and fixed NBR bumpers absorb end-stop impact, while the riveted body drastically reduces axial mounting depth compared to conventional round-body cylinders.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25SB Is Used
CNC Fixture Clamping
Secures aluminum housings during CNC milling. The 628.3 N extend force locks the part firmly, while the short 25 mm stroke keeps the fixture profile minimal.
Carton Flap Folding
Drives mechanical arms to fold corrugated box flaps at high speed. The fixed NBR bumpers absorb the impact at the end of the 25 mm travel without requiring external cushions.
Belt Diverter Gate
Actuates a sorting deflector plate on a parcel conveyor. The male M14x1.5 rod thread provides a rigid connection to the gate linkage, handling the 527.8 N retract load reliably.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25SB the Right Cylinder?
When sizing this 40 mm bore, step down to the SDA32 which provides 402.1 N push at 0.5 MPa, or step up to the SDA50 yielding 981.7 N push at 0.5 MPa. At 0.5 MPa, this model offers a safe working load of roughly 377 N (about 60% of its 628.3 N capacity) and can vertically lift approximately 32 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 40 mm bore, 25 mm stroke, PT1/8 port, built-in magnet, and male M14x1.5 rod thread. Note that a standard compact cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only decelerates the stroke end rather than locking the load. For vertical holding without live pressure, integrate 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-SDA40X25SB FAQ
This 40 mm bore double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa. At 0.7 MPa, it provides 879.6 N push and 738.9 N pull. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and sustains speeds of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the SDA40X25SB; it shares the exact same physical specs, seals, and dimensions as the base model. It does not have adjustable air cushions. Instead, it relies on fixed NBR bumpers at both ends to decelerate the piston. For high-energy or high-speed cycles, you should add an external shock absorber or slow down the approach speed.
