Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 10mm 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 ACQJ125X10-10S
The AirTAC ACQJ125X10-10S is a big-bore JIS compact pneumatic cylinder with a 10 mm full stroke and a 10 mm adjustable extend window. An external M27x2.0 threaded stopper with a lock nut lets you fine-tune the extend end position on the machine, giving a usable forward range of 0 to 10 mm. The return stroke remains completely unaffected.
Because the adjuster only limits travel distance and not piston area, output force is identical to a standard ACQ of the same size. You get 6135.9 N push and 5733.8 N pull at 0.5 MPa, with a maximum push capacity of 1251 kgf at 1.0 MPa. The -S magnet enables detection via reed or solid-state switches, while fixed NBR elastomer bumpers handle end-of-stroke deceleration.

| Bore size | Ø125 mm |
| Full stroke | 10 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 ACQJ125X10-10S Is Used
Press Fit Depth Tuning
Dial in precise 0-10 mm insertion depths for heavy press operations without machining new spacers, allowing rapid setup changes between varying component heights.
Large Assembly Forming
Provide adjustable end-stops for heavy-duty metal forming or joining jigs where the final squeeze distance must be trialed and locked on the fly during product changeover.
Heavy Load Positioning
Fine-tune the extend limit on lifting or plunging stations to accommodate varying pallet thicknesses, ensuring consistent contact without re-teaching valve timings.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10S the Right Cylinder?
Select this 125 mm bore model when your fixture requires exact 0-10 mm forward positioning combined with massive thrust. If the full 10 mm stroke is always needed without variation, a fixed-stroke ACQ suffices. For slightly different force needs, the smaller 100 mm bore provides 3927.0 N push @0.5 MPa, while the larger 160 mm bore yields 10053.1 N. Confirm ordering essentials: 125 mm bore, 10 mm full stroke, 10 mm window, S magnet, and the default female M22x2.5 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 ACQJ125X10-10S FAQ
It delivers 6135.9 N push and 5733.8 N pull 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 10 mm with a 10 mm adjustable window, allowing a usable extend range of 0 to 10 mm.
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. Fixed NBR bumpers handle end-of-stroke deceleration, and the -S magnet works with reed or electronic switches.
