Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X200-40SB
The AirTAC ACQJ32X200-40SB is a double-acting JIS compact cylinder with a 200mm stroke and a 32mm bore. An external M12x1.25 threaded stop and lock nut restricts the extend end position, providing a usable extend range of 160-200mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, the output force is identical to a standard ACQ of this bore.
This unit includes a male M14x1.5 rod end (-B) for direct load coupling and a built-in piston magnet (-S) for tracking with reed or solid-state switches. Featuring a 200mm stroke, it is a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore size. Braking is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 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 |
| Temperature | -20 to +70 °C |
| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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.

Press Fit Positioning
Dial in exact downward extension limits for light-duty press fitting tasks during prototype assembly runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-40SB the Right Cylinder?
Selecting this bore yields 402.1N of push force and 301.6N of pull force at 0.5MPa, with 562.9N push at 0.7MPa. If your application requires less thrust, dropping to a 25mm bore provides 245.4N of push force, while stepping up to a 40mm bore offers 628.3N. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, confirm the 32mm bore, 200mm full stroke, 40mm window, male rod thread, and magnet.
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 ACQJ32X200-40SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The usable extend range is 160-200mm, achieved by shortening the 200mm full stroke up to 40mm via the external stop. The retract stroke is unaffected.
The external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, allowing on-machine tuning without new parts. The adjuster changes the stroke length only, so the output force remains identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers, not adjustable air cushions.
