Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20S 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 ACQJ80X80-20S
The AirTAC ACQJ80X80-20S is a double-acting JIS compact cylinder with an external extend stop. A threaded M20x1.5 adjuster and lock nut let you set the extend stroke anywhere from 60 to 80 mm directly on the machine, while the retract movement remains completely unaffected. The full 80 mm travel is set by the model, and the 20 mm window is how much you can shorten the forward stroke.
Because the 80 mm piston area is unchanged, output force is identical to a standard ACQ of this bore. You get 2513.2 N push and 2267.8 N pull at 0.5 MPa, scaling to 3518.5 N push at 0.7 MPa, with a maximum push of 513 kgf at 1.0 MPa. The unit features a 25 mm rod, PT3/8 porting, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The built-in piston magnet (-S) works with reed or electronic solid-state switches via the integrated mounting grooves.

| Rod thread | M16×2.0 (F) / M22×1.5 (B) |
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 ACQJ80X80-20S Is Used
Press Fit Depth Tuning
Set precise press-in depths for bearings or pins on an assembly line, allowing rapid 60-80 mm adjustment without swapping cylinders when product heights change.
Product Changeover Stops
Adjust the mechanical stop position on packaging conveyors to accommodate different carton lengths quickly, avoiding the need for custom spacers.
Machine Setup Trials
Dial in the exact end position during CNC or robotic machine commissioning, testing various extend endpoints safely before locking the nut down.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20S the Right Cylinder?
If your forward thrust needs are slightly lower, the 63 mm bore yields 1558.6 N push at 0.5 MPa. For heavier drives requiring more power, the 100 mm bore provides 3927.0 N push at 0.5 MPa. If your end-position never varies, a fixed-stroke ACQ80x80 is simpler and avoids adjuster setup. When ordering this adjustable version, confirm the 80 mm bore, 80 mm full stroke, 20 mm window, the -S magnet, and the default 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 ACQJ80X80-20S 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 80 mm, but the external stop allows you to shorten the extend stroke by up to 20 mm, giving a usable extend range of 60-80 mm. The retract stroke remains fixed at 80 mm.
The external M20x1.5 threaded stop physically limits how far the rod extends, letting you fine-tune the forward end position on the machine. It does not change the piston area, so force is identical to a standard ACQ80. The cylinder uses fixed elastomer bumpers for deceleration, not adjustable air cushions, so for high-energy loads you should slow the approach or use an external shock absorber.
