Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40B 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 ACQJ32X150-40B
The ACQJ32X150-40B is a double-acting JIS compact cylinder featuring a 150mm stroke that exceeds the standard 100mm maximum for a 32mm bore, classifying it as a made-to-order long-stroke variant. An external threaded stop with a lock nut limits the EXTEND end position, allowing you to fine-tune the usable extend range from 110mm up to 150mm without swapping components. The RETRACT stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5 MPa. The -B suffix indicates a male-thread piston rod end (M14x1.5) that couples directly to your load. This unit ships without a magnet but retains sensor grooves in the body, and it relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion.

| 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 ACQJ32X150-40B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture, compensating for varying raw stock thicknesses by adjusting the extend stop from 110mm to 150mm.
Carton Forming Stops
Set precise tuck or fold depths on a packaging line during product changeover, using the external adjuster to match new carton dimensions instantly.
Assembly Press Trials
Establish the correct insertion depth for a new component on an assembly press by testing intermediate end positions before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40B the Right Cylinder?
If your application requires less push force, stepping down to a 25mm bore yields 245.4N push @0.5 MPa, while moving up to a 40mm bore provides 628.3N push @0.5 MPa. A standard fixed-stroke ACQ is sufficient if your end position never varies and on-machine adjustability is not required. When ordering this cylinder, confirm the 32mm bore, the 150mm full stroke, the 40mm adjustable window, the male rod thread (-B), and note that no magnet (-S) is included.
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 ACQJ32X150-40B FAQ
Force is identical to a standard ACQ: 402.1N push and 301.6N pull @0.5 MPa, 562.9N push @0.7 MPa, with a maximum push of 82 kgf @1.0 MPa. The full stroke is 150mm with a 40mm adjustable window, giving a usable extend range of 110-150mm. The piston rod is Ø16mm, the port is PT1/8, the male rod-end thread is M14x1.5, and the external adjuster thread is M12x1.25.
The external threaded stop limits the extend stroke length only, meaning force remains unchanged. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads. A plain compact cylinder does not hold its load on air loss; the rod drifts, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
