About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X20
The AirTAC B01-ACQ40X20 is a double-acting JIS compact cylinder engineered for tight axial spaces. The B01- prefix designates this as an application-dedicated (customer-specified) variant of the standard ACQ40X20, retaining exact mechanical equivalence to the base model. It delivers a robust 628.3 N push and 527.8 N pull force at 0.5 MPa, utilizing a 16 mm piston rod.
This 40 mm bore unit features a hard-anodized aluminum body joined by a C-clip and riveted construction to minimize overall length. Deceleration is handled by a fixed NBR elastomer bumper at each end, which is not field-adjustable. The female rod end utilizes an M8x1.25 thread, and the pneumatic supply connects via a PT1/8 port.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X20 Is Used
CNC Fixture Clamping
Secures aluminum engine blocks during machining operations, utilizing the 628.3 N extend force to lock parts firmly against locating pins.
Carton Flap Folding
Drives mechanical arms to tuck corrugated box flaps prior to tape sealing, where the short 20 mm stroke and compact body fit neatly within narrow conveyor side frames.
Component Insertion
Presses bearings into sheet metal housings on an automated assembly line, relying on the consistent 527.8 N retract force to extract the tooling quickly.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X20 the Right Cylinder?
When sizing this actuator, stepping down to the 32 mm bore yields 402.1 N push, while stepping up to the 50 mm bore provides 981.8 N push at 0.5 MPa. This 40 mm option fits perfectly between those two force classes. To order, confirm the 20 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the absence of a sensor magnet.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered; the rod drifts until the bumper makes contact. For fail-safe position holding, an external rod lock or pilot-operated check valve must be integrated into your circuit.
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-ACQ40X20 FAQ
At 0.5 MPa, the push (extend) force is 628.3 N and the pull (retract) force is 527.8 N. At 0.7 MPa, the push force reaches 879.6 N. The maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with an operating speed of 30-500 mm/s.
The B01- prefix simply indicates an application-dedicated (customer-specified) build of the standard ACQ40X20; it shares identical specifications, including the 40 mm bore and 16 mm rod. This model uses fixed NBR elastomer bumpers at the stroke ends rather than adjustable air cushions, so for high-energy cycles you should slow the approach or add external shock absorbers.
