Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 200mm 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 ACQJ125X200-10SB
The AirTAC ACQJ125X200-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND end position. You can fine-tune the extend stroke on the machine across a 190-200mm usable range (200mm full stroke minus up to a 10mm window) using the M27x2.0 adjuster thread. The RETRACT stroke remains completely unaffected.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 6135.9N push at 0.5MPa. This big-bore compact variant includes a -S magnet for reed or solid-state switches and a -B male piston rod end (M30x1.5) for direct coupling. It relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 200 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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 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 ACQJ125X200-10SB Is Used
Press Tooling Setup
Dial in the exact extend-end position during press tooling setup without machining new spacers or swapping components.
Heavy Fixture Changeover
Adapt large industrial fixtures rapidly during product changeover by shifting the extend stop within the 10mm window.
Stamping Trial Positions
Test varying stroke depths on heavy stamping presses safely, relying on the fixed elastomer bumper for end-of-travel deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB the Right Cylinder?
When sizing this 125mm bore cylinder, note the 6135.9N push force at 0.5MPa; stepping down to an 80mm bore yields 2513.2N, while a 140mm bore provides 7696.9N. Select this adjustable model only if your application requires on-machine extend-end tuning; a fixed-stroke ACQ suffices for static positioning. Confirm your ordering essentials: 125mm bore, 200mm 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10SB FAQ
This cylinder provides 6135.9N push and 5733.8N pull at 0.5MPa, 8590.3N push at 0.7MPa, and a maximum push of 1251kgf at 1.0MPa. The usable extend range is 190-200mm, achieved by shortening the 200mm full stroke by up to the 10mm window.
The external M27x2.0 threaded stop alters only the extend stroke length, meaning force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads. Additionally, a plain ACQ-type does not hold its load on air loss; use an external rod lock for fail-safe holding.
