About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75
The AirTAC B01-SDA40X75 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA40X75, meaning it is mechanically identical to the standard model. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, operating within a 30-500 mm/s speed range.
Its short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. The 16 mm piston rod uses an M8x1.25 female thread (or optional male M14x1.5) to couple loads, while the hard-anodized bore wears well over time. End-stops rely on a fixed NBR bumper that decelerates the piston rather than an adjustable air cushion, so high-energy cycles may need external shock absorbers.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75 Is Used
PCB Handling Ejectors
Provides the 628.3 N push stroke needed to eject populated circuit boards from test fixtures without demanding excessive axial mounting space.
Carton Flap Folders
Drives the mechanical arms that fold corrugated box flaps prior to sealing, utilizing the 75 mm stroke to clear the packaging path quickly.
Stamping Press Feeders
Pushes metal strip guides into position on small progressive stamping presses, taking advantage of the hard-anodized bore for pneumatic longevity.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75 the Right Cylinder?
When sizing this unit, stepping down to the SDA32 bore yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. This 40 mm model offers a safe working load of roughly 377 N (about 60% of its 628.3 N capacity) and can vertically lift approximately 32 kg with a 2:1 safety margin. To order, confirm the 75 mm stroke, PT1/8 port, and your preferred rod-end thread.
Because this is a plain double-acting cylinder, it cannot hold a load if air pressure drops or the valve is centered—the piston will drift. The fixed bumper only decelerates the stroke near its end and acts as neither a lock nor a brake. For applications requiring suspended load holding, 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-SDA40X75 FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a temperature range of -20 to +70 C.
The B01- prefix simply denotes an application-dedicated (customer-specified) build of the standard SDA40X75; all physical specifications remain identical. It does not have an adjustable air cushion. Instead, it uses a fixed NBR bumper at each end to decelerate the stroke. Additionally, this specific SKU lacks the -S magnet, so it cannot support reed or electronic switches.
