Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20
The AirTAC ACQJ80X50-20 is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend end position. With a full stroke of 50 mm and a 20 mm adjustment window, you can fine-tune the usable extend range from 30 mm up to 50 mm directly on the machine without swapping parts. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore. This 80 mm bore variant delivers 2513.2 N of push force and 2267.8 N of pull force at 0.5 MPa, utilizing a 25 mm piston rod and PT3/8 port. It relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion, and the body includes sensor grooves for adding reed or solid-state switches.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during part family changeovers, using the external stop to adapt the 30 to 50 mm extend position instantly.
Carton Sealing Turrets
Adjust the folding arm extension on the fly for varying box widths without disassembling the cylinder mount or changing out the entire actuator.
Press Tonnage Trials
Probe different end positions during light assembly press setup, fine-tuning the stroke window to find the exact contact point before locking the nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20 the Right Cylinder?
Select this 80 mm bore model when your application requires substantial force (2513.2 N push at 0.5 MPa) alongside precise extend end-position tuning within a 30 to 50 mm range. If you need slightly less force, the 63 mm bore provides 1558.6 N push at 0.5 MPa; stepping up to the 100 mm bore yields 3927.0 N push. A fixed-stroke ACQ is sufficient if the extend position never varies. When ordering, confirm the 50 mm full stroke, the 20 mm window, the female rod-end thread (M16x2.0), and whether you need the S magnet option for sensing.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20 FAQ
It 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 full stroke is 50 mm with a 20 mm window, allowing a usable extend range of 30 to 50 mm.
The M20x1.5 external adjuster screw with a lock nut mechanically limits how far the rod extends, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper, not an adjustable cushion or rod lock.
