Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 30mm 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 ACQJ140X30-10SB
The AirTAC ACQJ140X30-10SB is a double-acting JIS compact cylinder featuring a 140mm bore and a 30mm full stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 20mm up to 30mm directly on the machine. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this size, delivering 7696.9N push at 0.5MPa. This big-bore variant includes a male-thread piston rod end (M30x1.5) for direct load coupling and a built-in piston magnet (-S) for position sensing. It uses fixed elastomer NBR bumpers at each end rather than adjustable air cushions.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 30 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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ140X30-10SB Is Used
Press Changeover Stops
Adjust the 20-30mm extend stop during automotive press tooling changes to accommodate different material thicknesses without machining new spacer blocks.
Heavy Fixture Clamping
Dial in the exact clamping reach on large machining fixtures, using the male M30x1.5 rod thread to couple directly to heavy-duty clamp arms.
Packaging Plunger Setup
Set trial end positions for heavy product-forming plungers in packaging lines, relying on the 1570kgf max push to secure loads securely.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10SB the Right Cylinder?
Selecting this 140mm bore provides massive force in a compact footprint, pushing 7696.9N and pulling 7294.8N at 0.5MPa. If your application needs slightly less power, stepping down to a 125mm bore yields 6135.9N push, whereas moving up to a 160mm bore provides 10053.1N push. A fixed-stroke ACQ suffices if your end position never requires shifting; choose this adjustable model when trial end positions or product-changeover stops demand on-machine tuning. Confirm your ordering essentials: 140mm bore, 30mm full stroke, 10mm window, magnet (-S), and male rod thread (-B).
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 ACQJ140X30-10SB FAQ
This cylinder delivers a push force of 7696.9N and a pull force of 7294.8N at 0.5MPa, with a push of 10775.7N at 0.7MPa. The maximum push is 1570kgf at 1.0MPa. The full stroke is 30mm, and with the 10mm adjustable window, the usable extend range is 20-30mm.
The external M27x2.0 threaded stop with lock nut limits only the extend stroke length; it does not alter the piston area or reduce the output force. Deceleration is handled by fixed elastomer NBR bumpers at both ends, not adjustable air cushions. For fail-safe load holding on air loss, you must add an external rod lock or pilot-operated check valve, as the cylinder drifts when valve-centered.
