Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10SB 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 ACQJ40X150-10SB
The ACQJ40X150-10SB is a double-acting JIS compact cylinder featuring a 150mm stroke and a 40mm bore, built as a made-to-order long-stroke variant since it exceeds the 100mm standard maximum for this size. An external M12x1.25 threaded stop with a lock nut restricts the outward travel, providing a usable extension range of 140 to 150mm. The return stroke remains completely unaffected by this mechanism.
Output force stays identical to a standard ACQ of the same diameter because the adjuster solely alters travel length without modifying the piston area. You get 628.3N push and 527.8N pull at 0.5MPa, alongside an integrated piston magnet for reed or solid-state sensing and a male M14x1.5 rod end coupling directly to your load. NBR elastomer bumpers absorb impact at both ends.

| 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 |
| 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 (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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10SB Is Used
Machining Changeover
Dial in the extend stop from 140 to 150mm on a CNC lathe loader when swapping part families, avoiding the need to fabricate custom spacer collars.
Carton Forming Stops
Adjust the pusher end position on the fly to handle varying box depths without changing out mechanical hardstops on the packaging line.
Assembly Press Triage
Run trial end positions for a press fixture during new product introduction, locking the nut once the optimal 145mm contact point is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10SB the Right Cylinder?
Choosing this 40mm bore yields 628.3N push at 0.5MPa; stepping down to a 32mm bore drops that to 402.1N, while a 50mm bore raises it to 981.8N. If you never need to vary the end position, a fixed-stroke ACQ40X150 is simpler and avoids the external adjuster. Confirm your ordering essentials: 40mm bore, 150mm full stroke, 10mm window, S magnet, and B male rod thread.
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 ACQJ40X150-10SB FAQ
It delivers 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. The 10mm window allows the extend stroke to be fine-tuned within a 140 to 150mm usable range.
No, the adjuster only limits stroke length, so force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for end-of-stroke deceleration rather than adjustable air cushions. Note that on air loss, the rod drifts, requiring an external rod lock for fail-safe load holding.
