Airtac ACQ Ultra Thin Air Cylinder ACQ63X20
The AirTAC Airtac ACQ Ultra Thin Air Cylinder ACQ63X20 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø63mm bore and 20mm 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 ACQ63X20
The AirTAC ACQ63X20 is a double-acting JIS compact cylinder engineered for substantial thrust within a minimal axial envelope. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The hard-anodized aluminum bore and riveted piston-to-rod joint ensure durable, leak-free operation in demanding industrial environments.
This 63 mm bore unit features a 20 mm stroke and utilizes a PT1/4 port to drive a 20 mm piston rod with a female M10x1.5 end thread. The integrated C-clip body design drastically reduces overall length compared to standard round-body cylinders, saving valuable machine footprint. Deceleration is handled by a fixed NBR elastomer bumper at each end stop, which is not field-adjustable; for high kinetic energy loads, consider slowing the approach speed or adding an external shock absorber.

Where the Airtac ACQ Ultra Thin Air Cylinder ACQ63X20 Is Used
Injection Mold Clamping
Secures medium-sized injection molding tooling halves during material injection, utilizing the 1558.6 N push force to maintain rigid alignment.
Pallet Diverting
Pushes heavy pallets onto branching conveyor lanes in distribution centers, relying on the compact 63 mm body to fit within tight transfer zone clearances.
CNC Lathe Unloading
Ejects finished turned parts from a CNC lathe spindle, where the 20 mm stroke and female M10x1.5 rod thread securely couple to the extraction gripper.
Is the Airtac ACQ Ultra Thin Air Cylinder ACQ63X20 the Right Cylinder?
When sizing this model, compare its 1558.6 N push at 0.5 MPa against adjacent bores: stepping down to the 50 mm bore yields 981.8 N, while stepping up to the 80 mm bore provides 2513.2 N. Remember that a plain ACQ body does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end; a fail-safe hold requires an external rod lock or pilot-operated check valve. To order, confirm the 63 mm bore, 20 mm stroke, PT1/4 port, female M10x1.5 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 ACQ Ultra Thin Air Cylinder ACQ63X20 FAQ
The ACQ63X20 delivers a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push force is 2182 N. The maximum push force is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific model ships without a sensor magnet, though the body retains standard grooves for AirTAC reed or electronic switches if a magnet is added later. Additionally, it uses a fixed NBR elastomer bumper at each end rather than an adjustable air cushion, meaning high-speed loads may require external deceleration planning.
