About the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X20
The AirTAC B01-ACQ20X20 is a double-acting JIS compact cylinder engineered for space-constrained pneumatics. The leading B01- prefix denotes an application-dedicated (customer-specified) variant of the base ACQ20X20, meaning it shares the exact same mechanical architecture without any physical spec changes. It delivers 157.1 N of push force and 117.8 N of pull force at 0.5 MPa, utilizing a 10 mm piston rod and an M5x0.8 female rod-end thread.
The short C-clip and riveted body design significantly reduces axial mounting depth compared to traditional round-body cylinders. Deceleration at stroke ends is handled by a fixed TPU elastomer bumper rather than an adjustable air cushion, ensuring reliable end-stop absorption within the 30-500 mm/s operating speed range. While this specific SKU ships without a sensor magnet, the body retains integrated magnetic-switch grooves for future upgrades.

Where the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X20 Is Used
PCB Depaneling Router
Provides the 157.1 N push stroke to clamp circuit boards during automated routing and cutting operations without consuming excessive machine footprint.
Blister Pack Sealing
Drives the upper sealing die with precise 20 mm travel, utilizing the fixed TPU bumper to soften the impact at the end of the sealing cycle.
Lab Sample Dispensing
Actuates a 10 mm rod for metering valve control in analytical instruments, where the short C-clip body minimizes overall envelope dimensions.
Is the Airtac B01-ACQ Dedicated Pneumatic Cylinder B01-ACQ20X20 the Right Cylinder?
When sizing this 20 mm bore option, stepping down to a 16 mm bore reduces the 0.5 MPa push force to 100.5 N, while stepping up to a 25 mm bore increases it to 245.4 N. This 20 mm model provides a balanced middle ground for lighter-duty tasks. Remember that a plain compact cylinder like this does not hold its position if air pressure is lost or the valve is centered; the rod will drift, and the fixed bumper only decelerates it near the end of travel. For fail-safe load holding, an external rod lock or pilot-operated check valve is required. To order, confirm the 20 mm bore, 20 mm stroke, M5x0.8 port, default female rod thread, and no magnet.
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-ACQ20X20 FAQ
This 20 mm bore double-acting 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 force of 32 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa, with speeds of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the standard ACQ20X20, 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 each end to absorb the stop. For high-energy cycles, slow the approach or add an external shock absorber.
