About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X5
The B01-ACQ20X5 is an AirTAC application-dedicated (customer-specified) variant of the standard ACQ20X5, sharing identical mechanics. It is a double-acting, single-rod JIS compact cylinder engineered to deliver 157.1 N of push force and 117.8 N of pull force at 0.5 MPa. The short C-clip and riveted piston-to-rod assembly drastically reduce axial length, saving valuable mounting depth where a conventional round-body cylinder would not fit.
This 20 mm bore unit features a 10 mm piston rod and an M5x0.8 female rod-end thread for straightforward load coupling. End-of-stroke energy is managed by a fixed TPU elastomer bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-speed cycling. The body includes magnetic-switch grooves, though this specific SKU ships without the internal magnet.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X5 Is Used
PCB Pick & Place
Ideal for short 5 mm ejection strokes in electronic assembly, using its 157.1 N push force to pop components out of tape-and-reel carriers.
Carton Flap Tucking
Provides a rapid, compact tucking action in packaging lines where axial space is tight, utilizing the fixed TPU bumper to absorb the end stop.
Lab Dispenser Clamping
Secures small fluid vials in automated lab dispensing machinery, taking advantage of the 10 mm rod and short body footprint.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X5 the Right Cylinder?
When sizing this actuator, consider stepping down to the 16 mm bore (100.5 N push @0.5 MPa) for lighter duties, or up to the 25 mm bore (245.4 N push @0.5 MPa) if your payload requires greater extension force. Because this is a double-acting compact cylinder, it will not hold a load if air pressure is lost or the valve is centered—the piston drifts, and the fixed bumper only decelerates near the stroke end. For fail-safe positioning, an external rod lock or pilot-operated check valve is required. To order, confirm the 20 mm bore, 5 mm stroke, M5x0.8 port, female rod thread, and no magnet configuration.
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-ACQ20X5 FAQ
This 20 mm bore cylinder provides 157.1 N push and 117.8 N pull at 0.5 MPa, 219.9 N push at 0.7 MPa, and a maximum push of 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) line of the base ACQ20X5; mechanically, it is identical to the standard model. It uses fixed TPU elastomer bumpers at both ends, which are not field-adjustable, so you should slow the approach or add external shock absorbers for high-energy loads.
