Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X150-10
The AirTAC ACQJ40X150-10 is a double-acting JIS compact cylinder built for applications requiring precise extend-position tuning. It features a 150mm stroke and an external threaded stop with a lock nut, allowing you to fine-tune the extend length down by 10mm. This provides a usable extend range of 140 to 150mm, while the retract stroke remains completely unaffected. As a long-stroke made-to-order variant, it exceeds the standard 100mm maximum for this bore.
Because the adjustment only limits travel and not piston area, output force stays identical to a standard ACQ. At 0.5MPa it delivers 628.3N of push and 527.8N of pull. The body incorporates sensor grooves for reed or solid-state switches, though this specific SKU ships without a magnet. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 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 |

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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.

Set trial end positions for pressing bearings to precise depths without swapping the actuator.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10 the Right Cylinder?
Selecting this 40mm bore unit involves weighing its 628.3N push force at 0.5MPa against the 402.1N of a 32mm bore, or stepping up to a 50mm bore for 981.8N. If your extend position never varies, a fixed-stroke ACQ cylinder is simpler and more cost-effective. When ordering, confirm the 150mm full stroke, the 10mm window, the female M8x1.25 rod-end thread, and the PT1/8 port. Remember to add the -S magnet option if you need electronic or reed switch detection.
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 ACQJ40X150-10 FAQ
This model provides a usable extend range of 140-150mm via its 10mm window. It outputs 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend travel without altering piston area, so force remains unchanged. Fixed elastomer bumpers handle end-of-stroke deceleration. Note that a plain ACQ-type cylinder will drift and cannot hold a load on air loss; use an external rod lock for fail-safe holding.
