Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-40S
The ACQJ160X150-40S is a double-acting, single-rod JIS compact cylinder from AirTAC's big-bore range, featuring a 150 mm full stroke and an external M36x2.0 threaded stop with a lock nut. This mechanism lets you fine-tune the extend end position on the machine, providing a usable extension range of 110 to 150 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of the same bore, yielding 10053.1 N push at 0.5 MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Equipped with a -S piston magnet, the body grooves accept both reed and solid-state electronic sensors for position confirmation.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 150 mm |
| Adjuster thread | M36×2.0 |
| 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 | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ160X150-40S Is Used
Press Tonnage Tuning
Dial in the exact 110 to 150 mm extend position on a large metal stamping press without machining custom spacers for varying material thicknesses.
Heavy Fixture Changeover
Adapt large welding fixtures quickly during product changeover by rotating the external M36x2.0 stopper nut to meet new part dimensions.
Palletizing Stroke Limits
Adjust the end stop on the fly for packaging lines handling varying pallet heights, ensuring precise descent without reprogramming motion controllers.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-40S the Right Cylinder?
For context on sizing, stepping down to a bore 140 yields 7696.9 N push, while this 160 mm bore provides 10053.1 N push at 0.5 MPa, and the next size up is unavailable in this standard series. If your extend target never varies, a fixed-stroke ACQ cylinder suffices and saves setup time. When ordering, verify the 160 mm bore, 150 mm full stroke, 40 mm adjustable window, the -S magnet option, and the default female M24x3.0 rod-end 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 ACQJ160X150-40S FAQ
It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 150 mm with a 40 mm adjustable window, giving a usable extend range of 110 to 150 mm.
The external M36x2.0 threaded stop with lock nut limits only the extend length, meaning force remains identical to a standard ACQ. Deceleration uses a fixed elastomer bumper. A plain cylinder does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
