Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20S 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 ACQJ160X150-20S
The ACQJ160X150-20S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend end position. You get a usable forward travel range of 130 to 150 mm, dialed in directly on your equipment without swapping parts. The return stroke remains fixed at its standard length. As a big-bore variant, this unit supports up to 300 mm of total travel.
Thrust output remains identical to a standard ACQ of equivalent size, because the adjuster solely alters stroke length rather than piston area. It delivers 10053.1 N of push force and 9424.8 N of pull force at 0.5 MPa. The body incorporates fixed elastomer NBR bumpers at both ends for end-of-travel deceleration. Equipped with a piston magnet (-S), the unit operates seamlessly with either reed or electronic solid-state sensors.

| 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 ACQJ160X150-20S Is Used
Press Tooling Setup
Dial in the exact 130 to 150 mm extend position during press tooling setup, allowing operators to fine-tune contact depth without machining custom spacers.
Heavy Product Changeover
Accommodate heavy product changeovers on large assembly lines by quickly turning the external M36x2.0 stopper nut to match new part heights.
Lift Station Calibration
Establish trial end positions for heavy lift stations, safely testing intermediate extended heights before finalizing the mechanical hard stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20S the Right Cylinder?
When sizing this 160 mm bore actuator, stepping down to a 140 mm bore drops the 0.5 MPa push force to 7696.9 N, while this model provides 10053.1 N. If you need even more power, no larger bore exists in this series, so you would parallel two cylinders or increase pressure up to the 1.0 MPa maximum (yielding 2050 kgf max push). Choose a fixed-stroke ACQ if your end position never varies. To order this adjustable version, confirm the 150 mm full stroke, 20 mm window, S magnet, and the default female M24x3.0 rod end. Note that a plain compact cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if you require fail-safe load holding.
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 ACQJ160X150-20S FAQ
It provides 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 usable extend range is 130 to 150 mm (a 20 mm adjustment window off the 150 mm full stroke).
The M36x2.0 threaded stopper limits forward travel without changing the piston area, so thrust remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Because it is a pneumatic actuator, the rod will drift on air loss, so you must add an external rod lock for fail-safe holding.
