Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 200mm 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 ACQJ40X200-10B
The AirTAC ACQJ40X200-10B is a double-acting JIS compact cylinder featuring a 200mm stroke and a male M14x1.5 rod end. As a long-stroke made-to-order variant, it exceeds the standard 100mm maximum for this bore. An external M12x1.25 threaded stop and lock nut allows you to fine-tune the extend end position on the machine, yielding a usable extend range of 190-200mm without changing parts.
Because the piston area remains unchanged, output force is identical to a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. The retract stroke is unaffected by the adjuster. This unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion, and operates between 0.15 and 1.0 MPa.

| Bore size | Ø40 mm |
| Full stroke | 200 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 ACQJ40X200-10B Is Used
Machine Tool Changeover
Dial in the extend stop precisely during product family changeovers on machining centers without swapping out the entire actuator assembly.
Extended Transfer Diverter
Fine-tune the pusher stroke distance on a 200mm transfer line to accommodate varying package widths on the fly.
Long-Reach Clamping Fixture
Adjust the clamping endpoint during prototype setup on a long-reach fixture, testing different end positions before finalizing the mechanical stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10B the Right Cylinder?
This 40mm bore provides a middle-ground option, stepping up from the 32mm bore (402.1N push at 0.5MPa) or down from the 50mm bore (981.8N push). A fixed-stroke ACQ is sufficient if your extend endpoint never requires adjustment. When ordering, confirm the 40mm bore, 200mm full stroke, 10mm window, the male M14x1.5 rod thread, and note that this configuration ships without a magnet. For load holding on air loss, specify an external rod lock or pilot-operated check valve, as a plain cylinder drifts when valve-centered.
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 ACQJ40X200-10B FAQ
This cylinder delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The full stroke is 200mm with a 10mm window, allowing an adjustable usable extend range of 190-200mm.
The external M12x1.25 threaded stop with lock nut limits only the extend stroke length, meaning the force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration relies on fixed elastomer bumpers rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
