About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X50
The B01-ACQ40X50 is an AirTAC double-acting JIS compact cylinder featuring a 40 mm bore and 50 mm stroke. The leading "B01-" prefix designates this as an application-dedicated, customer-specified variant of the standard ACQ40X50, meaning it is mechanically identical to the base model but grouped for specific industry builds. It utilizes a short C-clip and riveted piston-to-rod assembly to drastically reduce overall axial length, saving valuable mounting depth where a conventional round-body cylinder would not fit.
Delivering 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, this unit is built for rigorous cyclic operation. The 16 mm piston rod terminates in a standard female M8x1.25 thread, while the body accepts air via a PT1/8 port. Instead of an adjustable air cushion, it relies on fixed NBR elastomer bumpers at both ends to absorb end-stop impact. The aluminum body features integrated magnetic-switch grooves, though this specific SKU ships without the internal magnet.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X50 Is Used
Injection Mold Ejection
Provides compact ejection force for plastic injection molding machines, utilizing the 628.3 N push output to strip finished parts from tight mold cavities.
Carton Flap Folding
Drives folding mechanisms on automated packaging lines, where the 50 mm stroke and space-saving body depth prevent interference with adjacent conveyor tooling.
PCB Pressing Fixtures
Applies precise clamping pressure in electronic assembly fixtures, benefiting from the 30-500 mm/s speed range and fixed NBR bumpers to protect delicate board components.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X50 the Right Cylinder?
When sizing this 40 mm bore model, stepping down to a 32 mm bore reduces the 0.5 MPa push output to 402.1 N, whereas stepping up to a 50 mm bore increases it to 981.8 N. Keep in mind that a standard ACQ body does not hold its position if air pressure drops or the valve is centered; the rod will drift, and the fixed bumper only decelerates the piston near the stroke end. For a fail-safe hold, an external rod lock or pilot-operated check valve is required. To order, confirm the 40 mm bore, 50 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the absence of 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-ACQ40X50 FAQ
This 40 mm bore cylinder provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N, with a maximum push capacity of 128 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
The B01- prefix simply indicates an application-dedicated, customer-specified variant of the ACQ40X50, sharing all exact physical specs of the base model. It does not have adjustable air cushions; it uses fixed NBR elastomer bumpers at both ends to absorb end-stop impact. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed.
