Airtac ACQ Ultra Thin Air Cylinder ACQ80X70FB
The AirTAC Airtac ACQ Ultra Thin Air Cylinder ACQ80X70FB is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø80mm bore and 70mm stroke, PT3/8 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 ACQ80X70FB
The AirTAC ACQ80X70FB is a double-acting JIS compact cylinder engineered to deliver 2513.2 N of push force at 0.5 MPa. Its short C-clip and riveted body architecture drastically reduces axial mounting depth compared to round-body units, making it highly effective for machinery where space is restricted. The 80 mm bore pairs with a 25 mm piston rod and a PT3/8 port to handle substantial pneumatic loads.
This specific configuration includes an FB mounting bracket for secure front-face attachment. Deceleration at stroke ends relies on a fixed NBR elastomer bumper, which is not field-adjustable; for high-energy cycles, utilizing an external shock absorber is recommended. The body features sensor grooves, though this unit ships without a magnet, and the female rod-end thread is M16x2.0.

Where the Airtac ACQ Ultra Thin Air Cylinder ACQ80X70FB Is Used
Plastic Injection Mold Clamping
Provides 2513.2 N of extend force at 0.5 MPa to secure injection mold halves within tight machine frames, utilizing the FB bracket for rigid front mounting.
Heavy Pallet Stopper
Acts as a robust pneumatic stop for heavy pallets on assembly lines, absorbing end-impact via the fixed NBR bumper while fitting into shallow conveyor profiles.
Corrugated Box Flap Folding
Drives large packaging machine flap folders at 30-500 mm/s, where the 70 mm stroke and M16x2.0 female rod end securely couple to the folding mechanism.
Is the Airtac ACQ Ultra Thin Air Cylinder ACQ80X70FB the Right Cylinder?
When sizing this 80 mm bore actuator, consider the 63 mm bore option providing 1558.6 N push at 0.5 MPa for lighter loads, or the 100 mm bore delivering 3927.0 N push for heavier demands. A standard ACQ cylinder will drift and lose its position if air pressure drops or the valve centers, as the fixed NBR bumper only decelerates the rod near the end of travel rather than locking it. To maintain a fail-safe hold, integrate an external rod lock or a pilot-operated check valve. To order this FB-bracket variant correctly, confirm the 80 mm bore, 70 mm stroke, PT3/8 port, female M16x2.0 rod thread, and the absence of a sensor 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 ACQ80X70FB FAQ
This 80 mm bore double-acting cylinder provides 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The operating pressure is 0.15-1.0 MPa with a speed range of 30-500 mm/s.
No, the ACQ80X70FB uses a fixed NBR elastomer bumper at each end to absorb the stop impact. It is not an adjustable air cushion, so for high-speed or high-energy loads, you should slow the approach or add an external shock absorber.
