Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X25
The AirTAC Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X25 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø40mm bore and 25mm stroke, PT1/8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.

About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X25
The B01-ACQ40X25 is a double-acting JIS compact cylinder featuring a 40mm bore and 25mm stroke. The leading B01- prefix designates this as an AirTAC application-dedicated (customer-specified) variant, mechanically identical to the standard ACQ40X25. It utilizes a short C-clip and riveted body construction to minimize axial footprint, saving valuable machine depth where a traditional round-body actuator cannot fit.
This model generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. The bore inner wall is hard-anodized for durability, and deceleration is handled by a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. The Ø16 mm piston rod features a default female M8x1.25 thread end for direct load coupling, operating via a PT1/8 port.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X25 Is Used
Package Diverting
Executes 25mm sorting gate movements on packaging conveyors, utilizing 628.3 N of thrust to push medium-weight cartons onto secondary lanes.
PCB Fixture Clamping
Secures circuit board assemblies during machining, where the short C-clip body conserves Z-axis height inside dense semiconductor test fixtures.
Component Ejection
Pushes molded parts out of small injection molds, relying on the fixed NBR bumper to absorb the end-stop impact without requiring external cushions.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ40X25 the Right Cylinder?
When sizing this actuator, stepping down to the 32mm bore yields 402.1 N push at 0.5 MPa, while stepping up to the 50mm bore provides 981.8 N push. This 40mm model strikes a middle ground for medium-duty handling. To confirm your ordering essentials: specify the 40mm bore, 25mm stroke, PT1/8 port, female rod thread, and note this unit ships without a sensor magnet.
Keep in mind that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the rod will drift. The fixed NBR bumper only decelerates the piston near the stroke ends and does not act as a locking brake. For a fail-safe hold, 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 / 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-ACQ40X25 FAQ
This 40mm bore double-acting cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. It operates within 0.15-1.0 MPa pressure, 30-500 mm/s speed, and -20 to +70 C temperature.
The B01- prefix indicates an AirTAC application-dedicated (customer-specified) build that is mechanically identical to the standard ACQ40X25. It does not have adjustable air cushions; instead, it uses fixed NBR elastomer bumpers at both ends to absorb end-stop shock.
