About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X40
The AirTAC B01-SDA25X40 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA25X40, meaning it is mechanically identical to the standard line with a 25 mm bore and 40 mm stroke. It provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa.
Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. The bore is hard-anodized, and deceleration at stroke ends relies on a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host magnetic switches without upgrading to the -S option.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X40 Is Used
PCB Depaneling Router
Actuates the cutting head feed on an inline PCB depaneling machine, utilizing the 40 mm stroke and 245.4 N push force to cleanly route individual boards without excessive axial footprint.
Carton Flap Folder
Folds minor flaps on a continuous motion carton erector, where the compact riveted body fits within tight side frames and the fixed NBR bumper absorbs the rapid end-stop impact.
Sorting Diverter Arm
Drives a short diverter arm on a package routing conveyor, offering reliable 12.5 kg vertical lift capacity with a 2:1 margin for lightweight product redirection tasks.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X40 the Right Cylinder?
This 25 mm bore generates 245.4 N of push force at 0.5 MPa, yielding a safe working load of roughly 147 N (about 60 percent of capacity) and a vertical lift capability near 12.5 kg with a 2:1 safety margin. If you need less force, the SDA20 provides 157.1 N; stepping up to the SDA32 gives 402.1 N. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the end of travel rather than locking the load. For position holding, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 40 mm stroke, M5x0.8 port, female rod-end thread, and no magnet.
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-SDA25X40 FAQ
This 25 mm bore cylinder provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the standard SDA25X40, sharing the exact same physical specifications. It does not have an adjustable air cushion; instead, it uses a fixed NBR bumper at each end to decelerate the piston. For high-speed applications, you should add an external shock absorber or slow the approach speed.
