About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X50B
The AirTAC B01-SDA25X50B is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA25X50B, meaning it is mechanically identical to the base model. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. The short riveted body significantly reduces axial mounting depth, saving valuable machine footprint where a round-body unit would not fit.
This specific SKU features a male-thread piston rod end (M8x1.25) for direct load coupling, paired with a 10 mm rod diameter. Because this unit lacks the -S option, it has no piston magnet and cannot support position sensing. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion. For high energy cycles, adding an external shock absorber is advised.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X50B Is Used
Carton Flap Folding
Drives the mechanical arms that fold corrugated carton flaps prior to tape sealing, utilizing the 50 mm stroke and male M8x1.25 rod end for precise, compact actuation.
Bottle Diverting Gate
Actuates a routing gate on a beverage filling line to divert glass bottles into a labeling station, fitting within the tight axial clearance between conveyor segments.
PCB Edge Clamping
Secures printed circuit boards during automated wave soldering, providing 245.4 N of clamping force at 0.5 MPa without overwhelming the delicate fiberglass substrate.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X50B the Right Cylinder?
When sizing this 25 mm bore, stepping down to the SDA20 yields 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. Based on the 245.4 N output at 0.5 MPa, the safe working load is roughly 147 N (about 60 percent capacity), translating to a vertical lift capability of approximately 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 50 mm stroke, M5x0.8 port, and the male M8x1.25 rod thread. Note that a plain cylinder drifts when air is lost or a valve is centered; the fixed bumper only decelerates near the end of travel and does not function as a lock. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
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-SDA25X50B FAQ
This 25 mm bore double-acting cylinder generates 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 between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
The B01- prefix designates this as an application-dedicated (customer-specified) variant of the SDA25X50B; mechanically, the dimensions, seals, and forces are identical to the standard model. Instead of an adjustable air cushion, it uses a fixed NBR bumper at each end to decelerate the stroke. Additionally, this version uses a male M8x1.25 rod thread and lacks a piston magnet, so it cannot be used with reed or electronic switches.
