About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40
The AirTAC B01-SDA40X40 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the base SDA40X40, meaning it is mechanically identical to the standard line with a 40 mm bore and 40 mm stroke. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa.
Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it highly effective for tight machine footprints. The bore is hard-anodized, and deceleration at stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet and therefore cannot support position sensing.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40 Is Used
Injection Mould Ejection
Provides compact ejection force for plastic injection moulding machines, utilizing the 628.3 N push output to safely knock finished parts out of the die cavity.
Packaging Line Diverter
Actuates routing gates on high-speed packaging conveyors, where the short riveted body minimizes axial intrusion into the transport lane.
CNC Fixture Clamping
Secures aluminium workpieces in CNC machining centers, delivering reliable clamping without occupying excessive vertical space.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X40 the Right Cylinder?
When sizing this actuator, step down to the SDA32 which provides 402.1 N of push at 0.5 MPa, or step up to the SDA50 which yields 981.7 N at the same pressure. For this 40 mm bore, the safe working load is approximately 377 N (about 60% of the 628.3 N figure), allowing a vertical lift of roughly 32 kg with a 2:1 safety margin. To order, confirm the 40 mm bore, 40 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no magnet. Note that a plain cylinder drifts when air is lost; the fixed bumper only decelerates near the end of travel and does not lock the load, so an external rod lock or pilot-operated check valve is required for 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-SDA40X40 FAQ
This 40 mm bore cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. 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 30-500 mm/s.
The B01- prefix designates an application-dedicated, customer-specified build of the standard SDA40X40, with no mechanical changes to the bore, seals, or force. This specific SKU does not have a piston magnet and cannot take a magnetic switch. If sensing is needed, select the -S variant to enable reed or electronic switches in the body grooves.
