Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-50SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm 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 ACQJ160X175-50SB
The AirTAC ACQJ160X175-50SB is a double-acting JIS compact cylinder from the big-bore range, featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 125 mm up to the full 175 mm on your machine without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore, delivering 10053.1 N push at 0.5 MPa. This variant includes a male M36x1.5 rod end and a built-in piston magnet (-S) for position sensing. It uses fixed NBR elastomer bumpers at each end rather than adjustable air cushions, operating effectively between -20 and +70 C at speeds of 30-500 mm/s.

| 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 |

| 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 ACQJ160X175-50SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 125 to 175 mm extend position during heavy press commissioning to accommodate varying material thicknesses without machining new spacers.
Automated Welding Changeover
Adjust the end stop on the fly when switching between automotive welding fixtures, ensuring the 40 mm rod places the toolhead precisely every time.
Large Assembly Line Indexing
Fine-tune the extend limit on a large assembly line to test trial end positions for new product variants before locking down the final mechanical stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-50SB the Right Cylinder?
Selecting this 160 mm bore provides massive thrust, pushing 14074.3 N at 0.7 MPa. If your application requires slightly less force, stepping down to a 140 mm bore yields 10775.7 N push at 0.7 MPa. If you need even greater power, this is the largest bore in the series, so you would need to twin cylinders or seek a different format. A fixed-stroke ACQ suffices if your end position never varies, but this ACQJ variant is essential for setups requiring on-the-fly stroke adjustments. Confirm your ordering essentials: 160 mm bore, 175 mm full stroke, 50 mm window, magnet, and 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 ACQJ160X175-50SB FAQ
This cylinder delivers a push force of 10053.1 N and a pull force of 9424.8 N at 0.5 MPa, with a push of 14074.3 N at 0.7 MPa. The maximum push is 2050 kgf at 1.0 MPa. The full stroke is 175 mm, and with the 50 mm adjustment window, the usable extend range is 125-175 mm.
The external M36x2.0 threaded stop with a lock nut limits the extend length without changing the piston area, meaning force remains identical to a standard ACQ. The retract stroke is unaffected. It uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, so for high-energy loads you should add an external shock absorber. Note that a plain ACQ does not hold its load on air loss; use an external rod lock for fail-safe holding.
