Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X175-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X175-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 175mm 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 ACQJ125X175-10SB
The AirTAC ACQJ125X175-10SB is a double-acting, big-bore JIS compact cylinder with an external threaded stop and lock nut that limits the EXTEND end position. You can fine-tune the extend stroke on the machine across a 165-175mm usable range (full 175mm stroke minus up to a 10mm window) without swapping parts. The RETRACT stroke remains completely unaffected. Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore. This Ø125mm variant features a 32mm piston rod, a PT3/8 port, and a male M30x1.5 rod-end thread (-B) that couples directly to your load.
Operating pressure spans 0.15-1.0 MPa, and the unit integrates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration. The -S option provides a built-in piston magnet compatible with reed or electronic (solid-state) magnetic switches. The external adjuster utilizes an M27x2.0 thread. Note that a plain ACQ-type cylinder does not hold its load on air loss or a centred valve; the rod drifts, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X175-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 175 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 ACQJ125X175-10SB Is Used
Press Tooling Setup
Dial in the exact 165-175mm extend position during press tooling setup to accommodate varying material thicknesses without machining new stop collars.
Automated Line Changeover
Execute rapid product-changeover stops on a large automotive assembly line by turning the external M27x2.0 adjuster to meet new model dimensions.
Heavy Fixture Trial Positions
Establish trial end positions on heavy metalworking fixtures, relying on the 1251 kgf max push at 1.0 MPa to move substantial masses while tuning the stroke.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X175-10SB the Right Cylinder?
When sizing this 125mm bore, stepping down to an 80mm bore yields 2513.2N push at 0.5 MPa, while stepping up to a 140mm bore provides 7696.9N push at 0.5 MPa. If your extend end position never varies, a fixed-stroke ACQ cylinder suffices. For this adjustable model, confirm the 125mm bore, the 175mm full stroke, the 10mm adjustment 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 ACQJ125X175-10SB FAQ
The force is identical to a standard ACQ of this bore: 6135.9N push and 5733.8N pull at 0.5 MPa, 8590.3N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa. The full stroke is 175mm, and the -10 window allows the extend stroke to be shortened by up to 10mm, yielding a usable extend range of 165-175mm.
An external M27x2.0 threaded stop with a lock nut limits the extend stroke length only; it does not change the piston area, so force remains unchanged. The retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. The -S magnet works with reed or electronic solid-state switches.
