Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B
The AirTAC ACQJ40X80-10B is a double-acting JIS compact cylinder featuring a male-thread piston rod (M14x1.5) and an external extend stop. A threaded screw with a lock nut limits the outward stroke, giving a usable extend range of 70-80mm from the 80mm full stroke. The retract distance remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of the same size. At 0.5 MPa it delivers 628.3N push and 527.8N pull. The body incorporates sensor grooves for switches, though this specific unit ships without a magnet. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| Bore size | Ø40 mm |
| Full stroke | 80 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| 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 | M8×1.25 (F) / M14×1.5 (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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B Is Used
Machining Fixture Clamps
Dial in exact clamping reach on machining fixtures during tooling setups, compensating for material thickness variations without swapping cylinders.
Product Changeover Stops
Rapidly reposition end stops on packaging lines during format changes, using the M12x1.25 adjuster to hit varied product lengths quickly.
Assembly Press Positioning
Test trial end positions on automated assembly presses, fine-tuning the 70-80mm outward travel to prevent over-travel on delicate components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B the Right Cylinder?
If your application only requires a fixed 80mm reach, a standard ACQ40X80 cylinder is sufficient and simpler. Step down to a 32mm bore for 402.1N push at 0.5MPa, or up to a 50mm bore for 981.8N push. Select this ACQJ variant when you need on-machine end-position tuning within a 10mm window. Confirm the 40mm bore, 80mm full stroke, 10mm adjuster, male M14x1.5 rod thread, and PT1/8 porting. Note that a plain cylinder drifts on air loss, so add an external rod lock for fail-safe holding.
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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10B FAQ
It provides 628.3N push and 527.8N pull at 0.5 MPa, 879.6N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The 10mm adjustment window allows a usable extend range of 70-80mm.
The external M12x1.25 threaded stop with lock nut limits extend length only, meaning force is unchanged from a standard ACQ. The cylinder uses fixed elastomer bumpers instead of air cushions. It will drift on air loss, so an external rod lock is needed for fail-safe load holding.
