Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X15
The AirTAC Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X15 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø20mm bore and 15mm stroke, M5×0.8 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-ACQ20X15
The B01-ACQ20X15 is a double-acting JIS compact cylinder delivering 157.1 N of push force and 117.8 N of pull force at 0.5 MPa. The leading "B01-" prefix designates this as an AirTAC application-dedicated (customer-specified) variant of the standard ACQ20X15. Mechanically, it shares the exact same physical specifications, offering a short C-clip and riveted body that minimizes axial footprint compared to traditional round-body options.
This 20 mm bore unit features a 10 mm piston rod and an M5x0.8 female rod-end thread. It relies on a fixed TPU elastomer bumper at each end to absorb end-stop impact rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific SKU ships without the internal magnet. Operating efficiently between 30-500 mm/s, it handles a 15 mm stroke with a maximum standard stroke capacity of 100 mm.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X15 Is Used
PCB Pick & Place
Ideal for electronic assembly handlers needing a short 15 mm stroke to push connectors onto printed circuit boards with 157.1 N of precise extend force.
Carton Flap Folding
Drives small folding mechanisms on packaging lines where the compact body depth saves axial space and the fixed TPU bumper quietly stops the 10 mm rod.
Lab Dispenser Actuation
Moves pipetting or liquid dispensing heads in analytical instruments, benefiting from the lightweight aluminum body and 30-500 mm/s speed range.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X15 the Right Cylinder?
When sizing this actuator, stepping down to the 16 mm bore yields 100.5 N of push force at 0.5 MPa, while stepping up to the 25 mm bore provides 245.4 N. The B01-ACQ20X15 is configured with an M5x0.8 port, a female M5x0.8 rod thread, and no sensor magnet. Keep in mind that a standard compact cylinder like this drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not lock the load. For fail-safe holding, 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-ACQ20X15 FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157.1 N of push force and 117.8 N of pull force. At 0.7 MPa, the push force increases to 219.9 N. The maximum push force is 32 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The B01- prefix indicates this is an application-dedicated (customer-specified) variant of the ACQ20X15, meaning it is mechanically identical to the base model. It does not have an adjustable air cushion; instead, it uses a fixed TPU elastomer bumper at both ends to absorb impact. For high-energy cycles, use an external shock absorber.
