Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100SB 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 ACQJ125X200-100SB
The ACQJ125X200-100SB is a big-bore JIS compact cylinder featuring a 125mm bore and a 200mm full stroke. An external M27x2.0 threaded stop with a lock nut lets you fine-tune the extend end position on the machine itself. With a 100mm adjustment window, the usable extend range runs from 100mm up to 200mm. The retract stroke remains completely unaffected by this mechanism.
Because the adjuster only limits travel length and not piston area, output force stays identical to a standard ACQ of this size. You get 6135.9N push and 5733.8N pull at 0.5MPa. The -S magnet enables position detection with reed or solid-state switches, while the -B male M30x1.5 rod end threads directly to your load. Fixed NBR elastomer bumpers absorb end-of-stroke impact without needing external cushioning valves.

| 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 ACQJ125X200-100SB Is Used
Press Tooling Setup
Dial in the exact clamping extension during press tooling setup without machining custom spacers or swapping actuators.
Heavy Fixture Changeover
Adapt end positions rapidly during heavy fixture changeover on large automated assembly lines to accommodate varying product dimensions.
Bending Machine Trials
Establish trial end stops for metal bending machines where the final material deflection requires iterative physical positioning.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100SB the Right Cylinder?
Choose this 125mm bore actuator when a setup requires substantial push force—up to 1251kgf at 1.0MPa—combined with variable extend positioning. If your application always operates at a fixed extension, a standard ACQ cylinder without the external stop is sufficient. When sizing, note that stepping down to a 100mm bore drops the 0.5MPa push to 3927.0N, whereas this 125mm unit delivers 6135.9N. Confirm your ordering essentials: 125mm bore, 200mm full stroke, 100mm window, magnet option S, and male rod thread B. Remember that a plain compact cylinder drifts on air loss; add an external rod lock for fail-safe load holding.
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 ACQJ125X200-100SB FAQ
This double-acting cylinder delivers 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 full stroke is 200mm, but the external adjuster provides a 100mm window, allowing the usable extend range to be set anywhere from 100mm to 200mm.
No, the external M27x2.0 threaded stop only shortens the extend travel distance; it does not alter piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The -S piston magnet works with both reed and electronic solid-state switches for position sensing.
