About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X5B
The AirTAC B01-SDA40X5B is a double-acting compact cylinder engineered for extremely short linear motion. The B01- prefix designates an application-dedicated (customer-specified) variant of the standard SDA40X5B, meaning it is mechanically identical to the base model but grouped for specific industrial builds. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa.
This unit features a male M14x1.5 piston rod thread for robust load coupling, paired with a 16 mm rod diameter. The riveted body design drastically reduces axial mounting depth compared to round-body cylinders, making it ideal for tight machine footprints. It relies on a fixed NBR bumper at each end to decelerate the stroke, and because this SKU lacks the -S magnet option, it cannot host magnetic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X5B Is Used
Short-Stroke Part Ejection
Ideal for stamping press ejectors where a 5 mm travel quickly clears a 32 kg metal blank from a die using 628.3 N of extend force.
PCB Fixture Clamping
Provides high holding force in minimal axial space on circuit board routing machines, utilizing the male M14x1.5 rod to secure delicate fixtures.
Packaging Gate Diverter
Actuates a short diverter gate on a high-speed packaging line, where the compact riveted body fits within tight conveyor frame clearances.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X5B the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA32 bore if your load requires less force, as it provides 402.1 N of push at 0.5 MPa. Conversely, if your application demands more power, the SDA50 bore offers 981.7 N at 0.5 MPa. This B01-SDA40X5B configuration provides a safe working load of roughly 377 N (about 60% of its 628.3 N capacity at 0.5 MPa), translating to a vertical lift capability of approximately 32 kg with a 2:1 safety margin.
Confirm your ordering essentials: a 40 mm bore, 5 mm stroke, PT1/8 port, and a male M14x1.5 rod thread (denoted by the B suffix). Note that a plain compact cylinder like this does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For load holding without live pressure, you must integrate an external rod lock or a 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-SDA40X5B FAQ
This double-acting cylinder provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates at a speed of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the SDA40X5B; mechanically, it is identical to the standard model. It does not have an adjustable air cushion. Instead, it uses 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 approach speed.
