Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-10SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-10SB 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 ACQJ80X80-10SB
The AirTAC ACQJ80X80-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the EXTEND end position. You can fine-tune the extend stroke on the machine across a 70-80 mm usable range (full 80 mm stroke minus up to a 10 mm window) without swapping parts. The RETRACT stroke remains unaffected. An M20x1.5 adjuster thread sets the limit.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. This unit includes a male M22x1.5 piston rod end (-B) for direct load coupling and a built-in magnet (-S) for position sensing. It features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ80X80-10SB Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture during part-changeover, using the external stop to set the 70-80 mm extend position precisely without altering the tooling.
Carton Sealing Flaps
Adjust the folding arm reach on a packaging line to accommodate varying carton heights, tweaking the extend limit on the fly to prevent crushing the box.
Press Tonnage Setup
Establish trial end positions on a light assembly press, fine-tuning the stroke down from 80 mm to 70 mm to test part seating before locking the nut for production.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-10SB the Right Cylinder?
If 2267.8 N pull at 0.5 MPa is insufficient, step up to the 100 mm bore (3524.8 N pull), or step down to the 63 mm bore (1401.5 N pull) if you need less force. Choose this ACQJ80X80-10SB variant specifically when your fixture setup requires trial end positions or product-changeover stops within that 70-80 mm range. If your application always operates at a fixed 80 mm extension, a standard ACQ80X80 will suffice. When ordering, confirm the 80 mm bore, 80 mm full stroke, 10 mm window, the -S magnet for electronic or reed switches, and the -B male M22x1.5 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 ACQJ80X80-10SB FAQ
The usable extend range is 70-80 mm (80 mm full stroke minus the 10 mm window). Force is identical to a standard ACQ: 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 external M20x1.5 threaded stop with a lock nut limits the extend stroke length only; it does not change the piston area or force. The cylinder uses fixed NBR elastomer bumpers for deceleration, not adjustable air cushions. Note that a plain ACQ-type cylinder will not hold its load on air loss or when a valve is centered; for fail-safe holding, install an external rod lock or pilot-operated check valve.
