Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75B 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 ACQJ32X150-75B
The AirTAC ACQJ32X150-75B is a double-acting JIS compact cylinder featuring a 32mm bore and a 150mm extended travel length. Because 150mm exceeds the 100mm standard maximum for this bore size, this unit is configured as a long-stroke made-to-order variant. It incorporates an external M12x1.25 threaded stop with a lock nut on the extend side, allowing you to fine-tune the usable extend range from 75mm up to the full 150mm directly on the machine. The retract stroke remains completely unaffected by this adjustment.
Since the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 402.1N push and 301.6N pull at 0.5MPa. This model includes the -B option, providing a male M14x1.5 rod-end thread for direct load coupling, and uses PT1/8 ports. It relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. While it lacks a -S magnet, the body retains sensor grooves for adding external switches.

| Bore size | Ø32 mm |
| Full stroke | 150 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 ACQJ32X150-75B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part heights on a milling fixture using the external stop, avoiding the need to fabricate custom spacer rings.
Carton Changeover
Quickly reset the extend endpoint during packaging line format changes to accommodate different box sizes without swapping out the entire actuator.
Assembly Press Tuning
Establish trial end positions for a press operation, testing insertion depths on new sub-assemblies before locking down the adjuster nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75B the Right Cylinder?
When sizing this unit, consider the neighbouring bores: a 25mm bore yields 245.4N push at 0.5MPa, while a 40mm bore provides 628.3N push. If your extend position never varies, a fixed-stroke ACQ32 cylinder is simpler and more cost-effective. For this adjustable model, confirm the 32mm bore, 150mm full stroke, 75mm adjustment window, and the male M14x1.5 rod thread. Note that a plain compact cylinder drifts on air loss; for fail-safe load holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ32X150-75B FAQ
The force is identical to a standard ACQ32: push is 402.1N and pull is 301.6N at 0.5MPa, push is 562.9N at 0.7MPa, and max push is 82kgf at 1.0MPa. The full stroke is 150mm, but the external stop allows you to shorten the extend stroke by 75mm, yielding a usable extend range of 75-150mm.
An external M12x1.25 threaded screw with a lock nut limits how far the rod extends, changing only the stroke length, not the force. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions. This unit lacks a -S magnet, but the body features grooves ready to accept reed or solid-state switches.
