Airtac ACQ Ultra Thin Air Cylinder ACQ50X50
The AirTAC ACQ Ultra Thin Air Cylinder ACQ50X50 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø50mm bore and 50mm 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 ACQ50X50
The AirTAC ACQ50X50 is a double-acting, single-rod JIS compact cylinder engineered to deliver 981.8 N of push force at 0.5 MPa and 1374.4 N at 0.7 MPa. Its short C-clip and riveted body architecture significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint space. The 50 mm bore features a hard-anodized inner wall and a 20 mm piston rod with a female M10x1.5 end thread for secure load coupling.
This model relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. While the body includes grooves for position sensing, this specific unit ships without a magnet; adding an -S option enables compatibility with AirTAC reed or electronic switches.

Where the Airtac ACQ Ultra Thin Air Cylinder ACQ50X50 Is Used
Injection Mold Ejection
Provides 981.8 N of push at 0.5 MPa to eject plastic parts from injection molds, where the short 50 mm stroke and compact body depth minimize interference with the press platen.
Carton Flap Folding
Drives mechanical arms to fold corrugated carton flaps prior to sealing, utilizing the fixed NBR bumper to absorb the repetitive end-stop shock at operating speeds up to 500 mm/s.
Press Die Clamping
Secures stamping die plates in a mechanical press, taking advantage of the 20 mm rod and female M10x1.5 thread to handle the 200 kgf maximum thrust capacity safely.
Is the Airtac ACQ Ultra Thin Air Cylinder ACQ50X50 the Right Cylinder?
When sizing this 50 mm bore unit, consider stepping down to the 40 mm bore (628.3 N push @0.5 MPa) for lighter duties, or up to the 63 mm bore (1558.6 N push @0.5 MPa) if your application demands greater thrust. The ACQ50X50 operates at 30-500 mm/s and utilizes a PT1/4 port. To finalize your order, confirm the 50 mm stroke, the female M10x1.5 rod thread, and that no sensor magnet is required for this configuration.
Keep in mind that a standard ACQ cylinder does not hold its position or load if air pressure drops or the valve is centered; the rod will drift. If your fixture must remain safely locked during a pneumatic failure, you must integrate an external rod lock or a pilot-operated check valve into your setup.
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 ACQ50X50 FAQ
This double-acting cylinder generates 981.8 N push and 824.6 N pull at 0.5 MPa, 1374.4 N push at 0.7 MPa, with a maximum push force of 200 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa and speeds of 30-500 mm/s.
No, it uses a fixed NBR elastomer bumper at each end, not an adjustable air cushion, so you may need an external shock absorber for high-energy loads. Additionally, it does not hold its load on air loss; you must add an external rod lock for fail-safe position holding.
