About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25
The AirTAC B01-SDA40X25 is a double-acting single-rod compact cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA40X25, meaning it shares the exact same mechanical architecture and physical specs. It delivers a 628.3 N push at 0.5 MPa, utilizing a hard-anodized 40 mm bore and a two-way piston seal.
Its short riveted body saves valuable axial mounting depth where a round-body or profile cylinder will not fit. End-of-stroke deceleration relies on a fixed NBR bumper, which is not field-adjustable. This specific SKU lacks a piston magnet, so it cannot directly host AirTAC reed or electronic switches without upgrading to the -S option.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25 Is Used
CNC Fixture Clamping
Secures aluminum housings in a CNC machining center using its 628.3 N extend force, fitting neatly into tight multi-pallet tombstone arrays.
Carton Flap Folding
Drives mechanical folding arms on a packaging line to tuck corrugated box flaps prior to tape sealing, operating reliably at 30-500 mm/s.
Sorter Diverter Gate
Actuates a routing diverter on a package conveyor, using the fixed NBR bumper to absorb the kinetic energy at the end of the 25 mm stroke.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25 the Right Cylinder?
When sizing this 40 mm bore, step down to the SDA32 which yields 402.1 N push, or step up to the SDA50 for 981.7 N push at 0.5 MPa. Based on the 628.3 N push figure, a safe working load is roughly 377 N (about 60 percent capacity), translating to a vertical lift of approximately 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 25 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no magnet. Because a plain double-acting cylinder does not hold its load on air loss or valve centering, the piston drifts; install an external rod lock or pilot-operated check valve if the application must hold position.
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-SDA40X25 FAQ
This 40 mm bore double-acting cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push is 128 kgf at 1.0 MPa. The standard stroke limit for this bore is 130 mm, and operating speed ranges from 30-500 mm/s.
The B01- prefix denotes an application-dedicated (customer-specified) line of the base SDA40X25; mechanically, it is identical to the standard model. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach velocity.
