Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm 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 ACQJ140X175-10SB
The AirTAC ACQJ140X175-10SB is a double-acting JIS compact cylinder featuring a 140mm bore and a 175mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable forward range of 165 to 175mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force equals that of a standard ACQ of this size.
This big-bore variant delivers 7696.9N push and 7294.8N pull at 0.5MPa. It includes an M30x1.5 male rod end for direct load coupling, a PT3/8 port, and a built-in magnet for electronic or reed switches. Fixed NBR elastomer bumpers absorb impact at both ends, operating effectively between -20 and +70C at speeds of 30-500mm/s.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 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 (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 ACQJ140X175-10SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 165 to 175mm extend reach during heavy press commissioning without machining new spacers or swapping components.
Automated Welding Changeover
Shift the forward stroke limit on the fly when adapting robotic welding fixtures for different automotive chassis dimensions.
Large Mold Trial Positions
Test various end-stop depths on large injection molding machinery to find the optimal clamping point before final lockdown.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10SB the Right Cylinder?
Selecting this 140mm bore provides 7696.9N push at 0.5MPa. Stepping down to a 125mm bore yields 6135.9N push, while stepping up to 160mm provides 10053.1N. If your machine never requires end-position tuning, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 175mm full stroke, 10mm adjuster window, S magnet, and 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 ACQJ140X175-10SB FAQ
It delivers 7696.9N push and 7294.8N pull at 0.5MPa, 10775.7N push at 0.7MPa, and a maximum push of 1570kgf at 1.0MPa. The full stroke is 175mm with a 10mm adjustment window, allowing a usable extend range of 165 to 175mm.
The M27x2.0 external threaded stop mechanically limits the extend length without altering piston area, so force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the rod near stroke ends, but a plain cylinder drifts on air loss; use an external rod lock for fail-safe holding.
