About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ12X5S
The B01-ACQ12X5S is an AirTAC double-acting, single-rod JIS compact cylinder. The B01- prefix designates an application-dedicated (customer-specified) variant of the standard ACQ12X5S, meaning it shares the exact same physical specifications while serving a specific industry need. It delivers a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa.
Designed to save axial mounting depth, its short C-clip and riveted body construction fits where round-body cylinders cannot. This 12 mm bore unit features a 6 mm piston rod, an M5x0.8 port, and a fixed TPU elastomer bumper at each end to absorb end stops. The built-in S magnet enables position detection using AirTAC reed or electronic switches along the body grooves.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ12X5S Is Used
PCB Probe Testing
Provides precise 5 mm downward travel to press test probes onto printed circuit boards without damaging the delicate traces.
Small Part Ejection
Pushes miniature plastic or electronic components out of an injection mold cavity using 56.5 N of extend force.
Micro-fluidic Valve Actuation
Toggles small directional valves in laboratory fluidic systems where a short 12 mm bore footprint is required.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ12X5S the Right Cylinder?
When sizing this actuator, stepping down is not an option as 12 mm is the smallest available bore. If your application requires slightly more power, the next bore up is 16 mm, which provides 100.5 N of push force at 0.5 MPa compared to this model's 56.5 N. Keep in mind that a plain compact cylinder like this drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary for fail-safe load holding. To order, confirm the 12 mm bore, 5 mm stroke, M5x0.8 port, built-in magnet, and female M3x0.5 rod-end thread.
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-ACQ12X5S FAQ
This 12 mm bore cylinder provides a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push force is 79.2 N, with a maximum push capacity of 12 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa, temperatures from -20 to +70 C, and speeds of 30-500 mm/s.
The B01- prefix simply marks this as an AirTAC application-dedicated (customer-specified) variant of the ACQ12X5S, meaning it is mechanically identical to the base model. It uses fixed TPU elastomer bumpers at both ends rather than adjustable air cushions, so for high-speed or high-energy loads, you should slow the approach or add an external shock absorber.
