About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40S
The AirTAC B01-SDA40X40S is a double-acting, single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA40X40S, meaning it is mechanically identical to the base model but grouped for specific customer builds. Delivering 628.3 N of push force at 0.5 MPa, it features a hard-anodized bore and a two-way piston seal for reliable linear motion.
Its short riveted body minimizes axial mounting depth, making it highly effective for machinery where a standard round-body unit would not fit. The included -S piston magnet enables position detection via an AirTAC reed or electronic switch seated in the body grooves. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits, rather than an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40S Is Used
PCB Routing Machine
Drives the Z-axis cutting head on an electronics routing system, utilizing the 628.3 N extend force to cleanly plunge tooling through FR4 fiberglass boards.
Carton Flap Folder
Folds corrugated box flaps on a continuous packaging line, where the short 40 mm stroke and compact body depth conserve valuable conveyor side-clearance.
Injection Mold Ejector
Pushes finished plastic parts out of an injection molding cavity, using the 16 mm rod and female M8x1.25 thread to couple securely to the stripper plate.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40S 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 which yields 981.7 N at the same pressure. For this specific configuration, the safe working load is approximately 377 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. To finalize your order, confirm the 40 mm stroke, PT1/8 port, built-in magnet, and the default female M8x1.25 rod-end thread. Note that a plain compact cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not lock the load, so add an external rod lock or pilot-operated check valve if the application requires 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-SDA40X40S FAQ
This 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 between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and travels at speeds of 30-500 mm/s.
The B01- prefix simply indicates an application-dedicated (customer-specified) variant of the SDA40X40S; the physical specifications, 40 mm bore, and 40 mm stroke remain exactly the same. It does not have an adjustable air cushion. Instead, a fixed NBR bumper absorbs impact at the stroke ends. For high-energy cycles, slow the approach speed or install an external shock absorber.
