Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10S 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 ACQJ140X30-10S
The AirTAC ACQJ140X30-10S is a double-acting, single-rod JIS compact cylinder engineered for big-bore pneumatic applications up to 300 mm. An external threaded stop with a lock nut restricts the forward extension, permitting precise on-site endpoint tuning without swapping components. For this unit, the usable extend span is 20-30 mm, achieved by subtracting up to 10 mm from the 30 mm full length, while the retract distance remains fixed.
Because the piston area stays constant, output thrust equals a standard ACQ counterpart, delivering 7696.9 N push and 7294.8 N pull at 0.5 MPa. The Ø32 mm piston rod features an M22x2.5 female end, and the adjuster utilizes an M27x2.0 thread. NBR elastomer bumpers absorb impact at both extremes, and the integrated -S magnet interfaces with reed or solid-state sensors.

| 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 |

| 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 ACQJ140X30-10S Is Used
Press Stroke Calibration
Dial in the exact 20-30 mm clamping reach on heavy metal-forming presses during setup, ensuring material thickness variations do not cause over-stroking.
Product Changeover Stops
Rapidly adapt end-position limits on packaging lines for different carton sizes, using the external M27x2.0 adjuster to shift the extend endpoint without replacing the cylinder.
Large Assembly Fixtures
Fine-tune the extension distance on automotive welding fixtures where the 7696.9 N push force must seat large components precisely against rigid stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X30-10S the Right Cylinder?
When sizing this 140 mm bore, dropping to the 125 mm variant reduces push thrust to 6135.9 N at 0.5 MPa, whereas stepping up to the 160 mm bore yields 10053.1 N. If your process never requires altering the forward endpoint, a fixed-stroke ACQ cylinder provides the same power without the external adjuster hardware. To order this adjustable unit correctly, verify the 140 mm bore, 30 mm full stroke, 10 mm window, -S magnet for switch detection, and female 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 ACQJ140X30-10S FAQ
This big-bore cylinder provides 7696.9 N push and 7294.8 N pull at 0.5 MPa, 10775.7 N push at 0.7 MPa, and a maximum push of 1570 kgf at 1.0 MPa. The adjustable window is 10 mm, yielding a usable forward range of 20-30 mm.
The external M27x2.0 threaded stop with lock nut mechanically limits how far the rod travels forward, shortening the stroke without changing the piston area, so thrust remains identical to a standard ACQ. NBR elastomer bumpers decelerate the load at both extremes, and the -S magnet works with reed or electronic solid-state switches.
