Airtac ACQ Ultra Thin Air Cylinder ACQ50X25
The AirTAC ACQ Ultra Thin Air Cylinder ACQ50X25 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø50mm bore and 25mm stroke, PT1/4 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 ACQ Ultra Thin Air Cylinder ACQ50X25
The AirTAC ACQ50X25 is a double-acting JIS compact air cylinder engineered to deliver 981.8 N of push force and 824.6 N of pull force at 0.5 MPa. By utilizing a C-clip and riveted piston-to-rod design, the overall axial length is drastically reduced compared to traditional round-body units, saving valuable mounting depth within tight machine footprints. The hard-anodized aluminum bore ensures low friction and extended service life across high cycle counts.
This specific configuration features a 20 mm piston rod with a standard female M10x1.5 thread end, operating at speeds from 30 to 500 mm/s via a PT1/4 port. Instead of an adjustable air cushion, the cylinder relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact. While the body includes grooves for magnetic switches, this particular model ships without a sensor magnet installed.

Where the Airtac ACQ Ultra Thin Air Cylinder ACQ50X25 Is Used
Pallet Diverting Gate
Provides the 981.8 N push force needed to rapidly actuate a heavy diverting arm on a packaging conveyor line, with the short 25 mm stroke fitting neatly between support frames.
CNC Fixture Clamping
Secures heavy cast iron engine blocks during machining operations, utilizing the 20 mm rod and female M10x1.5 thread to pull a custom mechanical clamp down onto the part.
Carton Flap Folding
Drives a mechanical folding blade on an automated carton erector, where the compact C-clip body minimizes axial depth and the NBR bumper absorbs the repetitive stroke impacts.
Is the Airtac ACQ Ultra Thin Air Cylinder ACQ50X25 the Right Cylinder?
When sizing your actuator, note that stepping down to a 40 mm bore drops the 0.5 MPa push force to 628.3 N, while moving up to a 63 mm bore increases it to 1558.6 N. This 50 mm model offers a robust 981.8 N push, striking a strong balance for medium-duty handling. Ensure you specify the 25 mm stroke, PT1/4 port, and the default female M10x1.5 rod thread when submitting your RFQ.
Because a standard ACQ body does not hold its position when air pressure is lost or the directional valve is centered, the rod will drift. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a lock or brake. If your application requires fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 ACQ Ultra Thin Air Cylinder ACQ50X25 FAQ
At 0.5 MPa, this double-acting cylinder provides 981.8 N of push force and 824.6 N of pull force. At 0.7 MPa, the push force reaches 1374.4 N, with a maximum push capacity of 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and speed is 30 to 500 mm/s.
No, the ACQ50X25 uses a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed. Additionally, this model does not include a sensor magnet, though the body retains grooves for adding reed or electronic switches if needed.
