Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-10B
The AirTAC ACQJ32X45-10B is a double-acting JIS compact cylinder with a 32mm bore and 45mm full stroke. An external M12x1.25 threaded stop and lock nut limits the extend end position, giving a usable forward range of 35 to 45mm. The retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this size.
This variant features a male M14x1.5 piston rod end for direct load coupling. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. Operating pressure is 0.15-1.0 MPa, and the body retains sensor grooves, though this specific unit ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 45 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 (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 ACQJ32X45-10B Is Used
CNC Fixture Clamping
Dial in the exact 35 to 45mm clamp extension on a CNC machining center without machining new spacer plates for different part heights.
Carton Sealing Stops
Adjust the forward stroke position on packaging lines during product changeovers to accommodate varying package dimensions quickly.
Assembly Press Trials
Set trial end positions for pressing bearings on automated assembly lines, allowing fine-tuning of the insertion depth before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10B the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm version drops the 0.5 MPa push force to 245.4N, while moving up to a 40mm bore increases it to 628.3N. If your application requires a fixed 45mm stroke without any end-position tuning, a standard ACQ32X45 cylinder will suffice. To order this adjustable type correctly, confirm the 32mm bore, 45mm full stroke, 10mm adjuster window, male rod thread (-B), and whether you need the -S magnet option for reed or solid-state switches.
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 ACQJ32X45-10B FAQ
The usable extend range is 35-45mm (45mm full stroke minus the 10mm adjustment window). Force is identical to a standard ACQ32: push is 402.1N and pull is 301.6N at 0.5 MPa, push is 562.9N at 0.7 MPa, and maximum push is 82kgf at 1.0 MPa.
The external M12x1.25 threaded stop with a lock nut mechanically limits the extend stroke length without changing the piston area or force. Deceleration relies on a fixed NBR elastomer bumper, not an adjustable air cushion. Note that a plain ACQ-type does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
