Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 75mm 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 ACQJ80X75-20S
The AirTAC ACQJ80X75-20S 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 usable extend range from 55 mm up to the full 75 mm directly on the machine without changing parts. The RETRACT stroke remains completely unaffected.
Because the piston area is unchanged, the force is identical to a standard ACQ of this bore, delivering 2513.2 N push at 0.5 MPa. The cylinder uses a fixed elastomer bumper at each end for end-of-stroke deceleration. The -S suffix indicates a built-in piston magnet compatible with reed or solid-state electronic switches.

| Bore size | Ø80 mm |
| Full stroke | 75 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 |

| 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 ACQJ80X75-20S Is Used
Machining Fixture Stops
Dial in the exact 55 to 75 mm extend position for varying part sizes on a milling fixture without machining new stop blocks.
Assembly Line Changeover
Quickly reset the extend end position during product family changeovers on automated assembly equipment to maintain correct clamping depth.
Carton Forming Trials
Establish the optimal end-of-stroke push-off distance for new carton board sizes on a packaging line before finalizing the mechanical setup.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20S the Right Cylinder?
If you need less push force, the 63 mm bore provides 1558.6 N at 0.5 MPa, while stepping up to the 100 mm bore yields 3927.0 N. Choose this 80 mm bore when your application requires approximately 2513.2 N of push force. If the extend end position never needs adjustment, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 80 mm bore, 75 mm full stroke, 20 mm adjustable window, the -S magnet option, and the 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 ACQJ80X75-20S FAQ
The usable extend range is 55 to 75 mm, set by the 20 mm adjustable window. Force is identical to a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and maximum push is 513 kgf at 1.0 MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke length only, so force remains unchanged. The retract stroke is unaffected. Deceleration is handled by a fixed elastomer bumper at each end, not an adjustable air cushion, so use an external shock absorber for high energy loads.
