About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20SB
The AirTAC ACQJ80X80-20SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke from 60 to 80 mm directly on the machine without swapping components, while the retract stroke remains completely unaffected. Equipped with a male M22x1.5 rod thread and a PT3/8 port, it couples directly to your load.
Because the internal piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N of push force at 0.5 MPa. The cylinder includes a built-in piston magnet for use with reed or electronic solid-state switches, and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| 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 ACQJ80X80-20SB Is Used
Varying Setup Fixtures
Dial in the exact extend end position for short-run machining fixtures without machining new spacer plates.
Product Changeover Stops
Adapt conveyor diverter stops on a packaging line quickly when switching to a different carton length.
Press Trial Positions
Test multiple engagement depths on an assembly press safely before locking the final 60-80mm extend range.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20SB the Right Cylinder?
If your application needs less thrust, the adjacent bore 63 provides 1558.6 N push at 0.5 MPa, whereas stepping up to bore 100 yields 3927.0 N. Choose this 80mm bore if you need 2513.2 N push force alongside on-the-fly 60-80mm extend tuning. If the exact 80mm extend position never varies, a fixed-stroke ACQ suffices. Confirm your ordering essentials: 80mm bore, 80mm full stroke, 20mm adjuster window, S magnet, and B male rod 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 ACQJ80X80-20SB 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 usable extend range is 60-80 mm via the 20 mm adjustment window.
The external M20x1.5 threaded stop with lock nut limits the extend stroke length only, meaning force is identical to a standard ACQ. It uses fixed elastomer bumpers, and since it is a plain cylinder, the rod will drift on air loss, requiring an external rod lock for fail-safe holding.
