About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X15
The AirTAC B01-SDA40X15 is a double-acting, single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA40X15, meaning it is mechanically identical to the base model. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, operating within a speed range of 30-500 mm/s.
Designed with a short riveted body, this unit drastically reduces axial mounting depth where a conventional round-body or profile cylinder would not fit. It features a hard-anodized 40 mm bore, a 16 mm piston rod, and PT1/8 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. This specific SKU lacks a piston magnet, so it cannot support magnetic sensing without upgrading to the -S option.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X15 Is Used
PCB Router Clamping
Secures printed circuit board panels during routing operations. The minimal 15 mm stroke provides high rigidity for vibration-heavy machining without consuming valuable Z-axis height.
Carton Flap Folding
Deploys quickly to fold minor flaps on packaging lines. The 628.3 N extend force easily overcomes cardboard resistance, while the compact body fits tightly within narrow conveyor side frames.
Stamping Pin Ejection
Ejects small metal pins from a progressive die set. The short stroke matches the ejection distance perfectly, and the fixed NBR bumper absorbs the impact of the rapid 30-500 mm/s motion.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X15 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 this 40 mm bore, the computed safe working load is roughly 377 N (about 60 percent of the 0.5 MPa push figure), translating to a vertical lift capacity of approximately 32 kg with a 2:1 safety margin. To order, confirm the 40 mm bore, 15 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the absence of a magnet. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
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-SDA40X15 FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum push force 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.
The B01- prefix simply designates this as an application-dedicated (customer-specified) variant of the SDA40X15; 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 piston near the stroke limits. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed.
