About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20SB
The AirTAC ACQJ80X75-20SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut on the extend side. This mechanism lets you fine-tune the forward end position on the machine, yielding a usable extend range of 55 to 75 mm. The return stroke remains completely unaffected. Because the internal piston area stays the same, output force is identical to a standard ACQ of this bore.
Operating pressure ranges from 0.15 to 1.0 MPa, and the unit integrates fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. This specific configuration includes a male M22x1.5 piston rod end for direct load coupling and a built-in magnet (-S) for position sensing. The PT3/8 port and Ø25 mm rod ensure robust airflow and structural integrity for heavy-duty tasks.

| 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 ACQJ80X75-20SB Is Used
Machining Changeover Stops
Dial in the exact extend position from 55 to 75 mm when swapping workholding fixtures on a CNC lathe, avoiding the need to machine custom spacer blocks.
Carton Sealing Tamping
Adjust the tamping head reach on the fly for varying box heights, ensuring consistent flap closure without changing out the pneumatic assembly.
Press Fit Depth Tuning
Set precise insertion depths for bearing presses during prototype runs, utilizing the M20x1.5 external adjuster to test end positions before finalizing the setup.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20SB the Right Cylinder?
When sizing this 80 mm bore actuator, note it delivers 2513.2 N of push force at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore provides 1558.6 N, while moving up to a 100 mm bore yields 3927.0 N. A fixed-stroke ACQ cylinder is sufficient if your end-position never varies, but this adjustable version is essential for setups requiring frequent product-changeover stops. Confirm ordering essentials: 80 mm bore, 75 mm full stroke, 20 mm adjust 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 ACQJ80X75-20SB FAQ
This 80 mm bore cylinder has a full stroke of 75 mm with a 20 mm adjustable window, giving a usable extend range of 55-75 mm. It provides 2513.2 N push and 2267.8 N pull force 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 adjuster features an M20x1.5 thread.
The external threaded stop with a lock nut limits only the extend stroke length, meaning output force remains identical to a standard ACQ cylinder. It does not alter the fixed NBR elastomer bumpers at each end. The included -S magnet works with both reed and electronic solid-state switches for end-position detection.
