Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30B 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 ACQJ32X200-30B
The AirTAC ACQJ32X200-30B is a double-acting JIS compact cylinder built for long-stroke applications requiring precise extend positioning. Featuring a 32mm bore and 200mm stroke, this made-to-order variant exceeds the standard 100mm length limit. An external M12x1.25 threaded stop and lock nut lets you fine-tune the extend travel on the machine, yielding a usable extension range of 170 to 200mm. The retract stroke remains completely unaffected.
Because the adjuster only limits travel, the piston area stays the same, meaning output force is identical to a standard ACQ of this size. You get 402.1N push and 301.6N pull at 0.5MPa. This unit includes a male M14x1.5 rod-end thread for direct load coupling, a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and PT1/8 ports. Note that it ships without a magnet.

| 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 (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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30B Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on CNC machining centers without machining new spacer blocks during product changeovers.
Sorter Diverter Tuning
Adjust the stroke length of package routing gates on conveyor lines to accommodate varying box sizes on the fly.
Assembly Press Positioning
Set trial end positions for pressing operations in automated assembly cells, allowing operators to find the optimal seating depth quickly.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30B the Right Cylinder?
Selecting this model requires verifying your spatial constraints, as the 200mm stroke places it in the long-stroke category beyond the 100mm standard maximum for a 32mm bore. If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder would suffice and simplify setup. When ordering, confirm the 32mm bore, 200mm full stroke, 30mm adjustment window, and the male rod thread (-B). For sizing context, stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while stepping up to a 40mm bore provides 628.3N push. This 32mm bore delivers 402.1N push and 301.6N pull at 0.5MPa, with a maximum push capacity of 82kgf at 1.0MPa.
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 ACQJ32X200-30B FAQ
This 32mm bore cylinder provides a push force of 402.1N and a pull force of 301.6N at 0.5MPa, with a push force of 562.9N at 0.7MPa. The maximum push force is 82kgf at 1.0MPa. The full stroke is 200mm, and with the 30mm adjustment window, the usable extend range is 170-200mm.
The external M12x1.25 threaded stop with lock nut limits only the extend stroke length; it does not alter the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions. Because it is a pneumatic cylinder, it will not hold a load if air pressure is lost, requiring an external rod lock for fail-safe holding.
