Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm 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 ACQJ80X80-50S
This double-acting single-rod JIS compact cylinder utilizes an external threaded stop with a lock nut to precisely limit the extend stroke. You can fine-tune the extend end position on the machine itself, yielding a usable extension range of 30 to 80 mm from the 80 mm full stroke. The retract movement remains completely unaffected.
Because the piston area is unchanged, the output force equals a standard ACQ of the same bore, delivering 2513.2 N of push force at 0.5 MPa. The body includes magnetic-switch grooves compatible with reed or solid-state sensors, and it relies on a fixed elastomer bumper at each end for deceleration.

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 ACQJ80X80-50S Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC lathe fixture during part-changeover without machining new stop collars.
Carton Sealing Plungers
Adjust the folding arm descent on the fly to accommodate various carton heights on a packaging line.
Press Tonnage Setup
Set trial end positions for a light-duty assembly press, tweaking the 30 to 80 mm range until the crimp depth is perfect.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50S the Right Cylinder?
If your application requires less push force, the adjacent 63 mm bore yields 1558.6 N at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927.0 N. A fixed-stroke ACQ cylinder is sufficient when your end position never varies. To order this adjustable version correctly, confirm the 80 mm bore, 80 mm full stroke, 50 mm window, the S magnet option, and the female M16x2.0 rod-end thread.
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 ACQJ80X80-50S FAQ
It delivers 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 usable extend range is 30 to 80 mm (a 50 mm window off the 80 mm full stroke). The port is PT3/8 and the external adjuster thread is M20x1.5.
No, the threaded stop only changes the extension length, so the force remains identical to a standard ACQ of the same bore. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. For high-energy loads, add an external shock absorber or slow the approach.
