Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm 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 ACQJ32X150-40SB
The ACQJ32X150-40SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. It provides a usable extend range of 110 to 150 mm, letting you fine-tune the forward stroke on the machine without changing parts. The retract stroke remains unaffected. This long-stroke made-to-order variant exceeds the standard 100 mm maximum for bore 32.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this size. You get 402.1 N push and 301.6 N pull at 0.5 MPa. The unit includes a male M14x1.5 rod-end thread for direct load coupling, a piston magnet for electronic or reed sensors, and fixed NBR elastomer bumpers at both ends.

| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X150-40SB Is Used
Machining Fixture Stops
Dial in the exact 110-150 mm extend position for varying part widths on a CNC machining fixture without swapping out the actuator.
Packaging Changeover
Rapidly reconfigure product pusher end stops during format size changes on a packaging line, using the external M12x1.25 adjuster.
Assembly Trial Positions
Test different extend endpoints during prototype assembly machine setup to find the optimal pressing depth before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40SB the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N push. If your equipment never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice. For this adjustable model, confirm the 150 mm full stroke, the 40 mm window, the M14x1.5 male rod thread, and the -S magnet when ordering.
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 ACQJ32X150-40SB FAQ
This 32 mm bore cylinder has a 150 mm full stroke with a 40 mm adjustable window, giving a usable extend range of 110-150 mm. Force is identical to a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external threaded stop with a lock nut limits the forward stroke length without changing the piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers at each end, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
