Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 30mm 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 ACQJ32X30-30B
The AirTAC ACQJ32X30-30B is a double-acting JIS compact cylinder featuring a 32mm bore and a 30mm full stroke. It includes a male-thread (M14x1.5) piston rod end for direct load coupling. An external M12x1.25 threaded stop with a lock nut lets you fine-tune the extend end position on the machine without swapping parts. The usable extend range spans 0-30mm, while the retract stroke remains completely unaffected.
Because the adjuster only limits travel length and not the piston area, the output force is identical to a standard ACQ of this bore. At 0.5 MPa, it delivers a 402.1N push and 301.6N pull force. The body incorporates fixed elastomer bumpers at both ends for end-of-stroke deceleration and includes sensor grooves, though this specific unit ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 30 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30B Is Used
Varying Fixture Stops
Adjust the extend stop from 0 to 30mm on machining fixtures to accommodate different part lengths without fabricating new mechanical spacers.
Product Changeover
Fine-tune the extend position rapidly during packaging line format changes, hitting exact contact points for varying carton sizes.
Trial End Positions
Dial in the exact extension distance during prototype assembly machine setup, locking the M12x1.25 adjuster nut once the ideal kinematics are found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30B the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm bore yields a 245.4N push at 0.5 MPa, whereas stepping up to a 40mm bore provides 628.3N. If your setup never requires altering the end position, a fixed-stroke ACQ32 cylinder will achieve the same output. To order, confirm the 32mm bore, 30mm full stroke, 30mm adjustable window, the male rod thread (-B), and your port thread (PT1/8 standard).
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 ACQJ32X30-30B FAQ
It provides a 402.1N push and 301.6N pull at 0.5 MPa, a 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 30mm with a 30mm adjustable window, giving a usable extend range of 0-30mm.
An external M12x1.25 threaded screw with a lock nut limits the extend travel, allowing on-machine position tuning. It changes only the stroke length, so force remains identical to a standard ACQ32. The cylinder uses fixed elastomer bumpers for deceleration, and a plain ACQ-type does not hold its load on air loss without an external rod lock.
