About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X75
The B01-ACQ25X75 is an AirTAC double-acting, single-rod JIS compact cylinder. The leading B01- prefix designates this as an application-dedicated, customer-specified variant of the base ACQ25X75, meaning it is mechanically identical to the standard model. It delivers a push force of 245.4 N and a pull force of 188.9 N at 0.5 MPa. Utilizing a C-clip and riveted piston-to-rod assembly, the overall axial length is drastically reduced compared to standard round-body cylinders, saving valuable mounting space.
This 25 mm bore unit features a 12 mm piston rod and uses an M5x0.8 port. To absorb end-of-stroke impacts, it relies on a fixed TPU elastomer bumper at each end rather than an adjustable air cushion. The body includes grooves for magnetic switches, though this specific SKU ships without the internal magnet. Operating efficiently between 30-500 mm/s, it handles a 75 mm stroke within its 100 mm standard stroke limit.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X75 Is Used
Carton Flap Folding
Provides the 245.4 N push force needed to fold corrugated cardboard flaps on packaging lines, fitting neatly into tight machine frames via its short C-clip body.
Package Diverting
Actuates a routing gate to sort lightweight parcels on a conveyor belt, utilizing the 75 mm stroke to push items cleanly into secondary lanes.
PCB Fixture Clamping
Secures printed circuit board assemblies during testing, where the fixed TPU bumper quietly stops the 12 mm rod without damaging delicate electronic components.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X75 the Right Cylinder?
When sizing this actuator, consider stepping down to the 20 mm bore if your load requires less force, which provides 157.1 N of push at 0.5 MPa. If your application demands more power, the 32 mm bore offers 402.1 N of push at the same pressure. Remember that a plain compact cylinder like this does not hold its position if air pressure is lost or the valve is centered; the rod will drift, and the fixed bumper only decelerates it near the stroke end. For fail-safe holding, an external rod lock or pilot-operated check valve is required.
To order, confirm the 25 mm bore, 75 mm stroke, M5x0.8 PT port, and the default female rod-end thread (M6x1.0). Because this model lacks the S option code, it does not include a sensor magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT / G / NPT)
- ✓ 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 Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ25X75 FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 188.9 N. At 0.7 MPa, the push force is 343.6 N. The maximum push force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, and the speed range is 30-500 mm/s.
The B01- prefix indicates this is an application-dedicated, customer-specified variant of the ACQ25X75, sharing the exact same physical specifications. It does not have adjustable air cushions; instead, it uses a fixed TPU elastomer bumper at both ends to absorb impact. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed.
