Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-40B 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 ACQJ40X200-40B
The AirTAC ACQJ40X200-40B is a double-acting JIS compact cylinder featuring a 200mm full stroke and an external adjuster that permits on-site extend length tuning from 160mm up to 200mm. This 40mm bore actuator delivers a push force of 628.3N at 0.5MPa, exactly matching a standard ACQ unit since the mechanical stop alters travel distance without affecting piston area. Retract travel remains fixed at the full 200mm. Equipped with a male M14x1.5 rod end, it links directly to tooling. It is a made-to-order long-stroke variant, exceeding the standard 100mm maximum for this bore size, and incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.
This unit lacks a piston magnet but retains the body sensor grooves for adding external solid-state or reed switches if needed. The external M12x1.25 adjustment thread and lock nut secure the desired end position firmly. Operating pressure spans 0.15 to 1.0MPa, with a speed range of 30-500mm/s. Note that a standard compact cylinder does not hold loads upon air loss; utilize an external rod lock for fail-safe positioning.

| 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 ACQJ40X200-40B Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC machining fixture during part-changeover without machining new spacer blocks.
Carton Folding Arms
Modify the extend reach on packaging line folding arms to accommodate varying carton widths on the fly.
Assembly Press Trial
Establish the perfect pressing depth for new product runs on an assembly press by testing positions within the 160-200mm window.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-40B the Right Cylinder?
If your setup needs less push, the adjacent 32mm bore yields 402.1N at 0.5MPa, whereas the larger 50mm bore provides 981.8N for heavier demands. If your extend endpoint is permanently fixed, a standard ACQ40X200 cylinder without the external stop suffices. When ordering this adjustable variant, verify the 40mm bore, 200mm full stroke, 40mm adjuster window, and the male M14x1.5 rod thread. Since this is a nonstandard long-stroke configuration, expect made-to-order lead times.
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 ACQJ40X200-40B FAQ
It has a 40mm bore, 200mm full stroke, and a 40mm adjustment window, giving a usable extend range of 160-200mm. Force matches a standard ACQ: 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 port is PT1/8.
An external M12x1.25 threaded stop with a lock nut limits the extend travel without altering force. Retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. This model lacks a piston magnet but retains sensor grooves for external reed or solid-state switches.
