Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 150mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB
The ACQJ140X150-10SB is a double-acting single-rod JIS compact cylinder from the big-bore range, featuring a 140mm piston and 150mm full stroke. An external threaded stop with a lock nut limits the EXTEND end position, giving a usable extend range of 140-150mm. The RETRACT stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, force output is identical to a standard ACQ of this bore.
Equipped with a male M30x1.5 rod-end thread, it couples directly to your load. The unit includes a built-in piston magnet (-S) compatible with reed or solid-state switches, and fixed NBR elastomer bumpers at each end. Operating pressure spans 0.15-1.0 MPa, with a PT3/8 port ensuring robust air delivery for heavy-duty cycles.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 150 mm |
| Adjuster thread | M27×2.0 |
| Port size | PT3/8 |
| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB Is Used
Press Tonnage Calibration
Dial in the exact 140-150mm extend position during press setup to calibrate tonnage without machining new spacers or swapping components.
Heavy Fixture Changeover
Shift the extend stop by up to 10mm on the factory floor when swapping large product fixtures, ensuring rapid line changeovers.
Forming Press Trials
Test varying end positions on a metal forming press to find the optimal material deformation depth before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB the Right Cylinder?
Selecting this Ø140 body yields a push force of 7696.9N and a pull of 7294.8N at 0.5MPa. Stepping down to a Ø125 bore drops the push to 6135.9N, while scaling up to a Ø160 bore raises it to 10053.1N. If your setup never requires end-position tweaking, a fixed-stroke ACQ cylinder will suffice. When ordering, verify the 150mm full stroke, the 10mm adjuster window, the -S magnet, and the -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 ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-10SB FAQ
At 0.5MPa it provides 7696.9N push and 7294.8N pull; at 0.7MPa push is 10775.7N. Maximum push is 1570kgf at 1.0MPa. The full stroke is 150mm with a 10mm window, allowing a usable extend range of 140-150mm.
No, the adjuster only changes the extend stroke length. Force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration, not an adjustable air cushion.
