Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100SB 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 ACQJ80X80-100SB
The ACQJ80X80-100SB 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 range from 0 up to 80 mm directly on your machinery without swapping components. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, the output force equals that of a standard ACQ80, delivering 2513.2 N of push at 0.5 MPa. This SB configuration includes a built-in piston magnet for electronic or reed switches, plus a male M22x1.5 rod-end thread for direct load coupling. It relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion.

| Model | Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 80 mm |
| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| 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 ACQJ80X80-100SB Is Used
Variable Machining Stops
Set precise extend endpoints from 0 to 80 mm on CNC or milling fixtures to accommodate different part lengths during production changeovers.
Package Diverter Tuning
Adjust the pusher rod extension on packaging conveyors on the fly to handle varying box dimensions without replacing the cylinder.
Assembly Press Calibration
Dial in the exact extend position during trial runs on an assembly press, locking the M20x1.5 adjuster nut once the desired depth is reached.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100SB the Right Cylinder?
If you need less thrust, the ACQJ63X80-100SB yields 1558.6 N push at 0.5 MPa, whereas stepping up to the ACQJ100X80-100SB provides 3927.0 N. Choose this 80 mm bore when your application demands up to 513 kgf maximum push at 1.0 MPa. If the end position never varies, a fixed-stroke ACQ80 suffices. Confirm your ordering essentials: 80 mm bore, 80 mm full stroke, 100 mm adjustment 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 ACQJ80X80-100SB FAQ
The usable extend range is 0-80 mm (full stroke 80 mm minus the 100 mm window). Force is identical to a standard ACQ80: push 2513.2 N and pull 2267.8 N at 0.5 MPa, push 3518.5 N at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa.
The external M20x1.5 threaded stop and lock nut mechanically limit how far the rod extends, shortening the stroke length only. The output force remains unchanged because the piston area is not altered. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions.
