Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X150-10SB
The ACQJ125X150-10SB is a big-bore JIS compact cylinder with a 150 mm full stroke and a 10 mm external adjustment window, allowing the extend end position to be fine-tuned directly on your equipment from 140 mm up to 150 mm without swapping parts. The retract movement remains completely unaffected by this external stop. As a double-acting single-rod unit, it delivers substantial power, generating 6135.9 N of push force at 0.5 MPa, identical to a standard ACQ because the adjuster alters stroke length only, not the piston area.
This variant includes a male M30x1.5 piston rod end for direct load coupling and a built-in magnet (-S) for position sensing. The sensor groove accommodates either reed or solid-state electronic switches. Operating at speeds up to 500 mm/s, the cylinder relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Note that a plain ACQ-type cylinder will drift and lose its load position on air loss, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.

| 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 |

| 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 ACQJ125X150-10SB Is Used
Heavy Press Tonnage
Provides 6135.9 N of thrust at 0.5 MPa for large pressing operations, with the 10 mm extend stop allowing precise height calibration during initial fixture setup.
Product Changeover
Adapts end positions rapidly on a large assembly line when switching between parts, tuning the extend stroke from 140 to 150 mm without replacing the cylinder.
Large Mold Clamping
Secures heavy molds with the M30x1.5 male rod thread, using the fixed NBR bumper to absorb high kinetic energy while hitting the exact clamping coordinate.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-10SB the Right Cylinder?
Selecting this Ø125 mm model provides a maximum push force of 1251 kgf at 1.0 MPa, stepping down from the Ø140 bore (1570 kgf) or up from the Ø100 bore (801 kgf). A fixed-stroke ACQ is sufficient if your end position never varies, but the ACQJ external stop is essential for setups requiring trial end positions or product changeover. When ordering, confirm the 125 mm bore, 150 mm full stroke, 10 mm adjustment window, the -S magnet requirement, and the -B male rod thread. The standard PT3/8 port and M27x2.0 adjuster thread are fixed by the bore size.

- ✓ 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 ACQJ125X150-10SB FAQ
This cylinder provides 6135.9 N push and 5733.8 N pull force at 0.5 MPa, 8590.3 N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa. The full stroke is 150 mm, and the external adjuster allows the usable extend range to be shortened by 10 mm, resulting in a 140-150 mm extend window.
An external M27x2.0 threaded stop with a lock nut limits the extend distance without changing the piston area, meaning force remains identical to a standard ACQ. The retract stroke is unaffected. The cylinder uses a fixed NBR elastomer bumper for deceleration, not an adjustable air cushion. For fail-safe load holding on air loss, an external rod lock is required.
