Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75S 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 ACQJ160X175-75S
The AirTAC ACQJ160X175-75S is a large-bore JIS compact cylinder engineered for double-acting operation with an external threaded stop and lock nut that restricts the extend end position. You can tune the usable forward stroke anywhere from 100 mm up to the full 175 mm directly on the machinery, removing the need to swap physical components during product changeovers. The retract distance remains completely unaffected by this adjustment.
Because the internal piston area stays constant, output force matches a standard ACQ of this exact size, delivering 10053.1 N of push at 0.5 MPa. The Ø40 mm rod utilizes an M24x3.0 female rod-end thread, while the M36x2.0 external adjuster handles the stroke limitation. This Ø160 variant belongs to the big-bore compact series, featuring fixed NBR elastomer bumpers at each end for end-of-stroke deceleration and a built-in magnet (-S) compatible with reed or solid-state electronic switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 175 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 ACQJ160X175-75S Is Used
Heavy Press Changeovers
Adapt large metal-forming presses to new material thicknesses by dialing in the 100-175 mm extend range without machining new stop collars.
Large Fixture Positioning
Set trial end positions on heavy welding fixtures to dial in clamping depth accurately before finalizing the mechanical hardstops.
Palletizing Height Stops
Modify the extend reach on automated palletizing tools to handle various pallet heights or box dimensions on the fly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75S the Right Cylinder?
When sizing this unit, dropping down to an ACQJ140 yields 7696.9 N push force at 0.5 MPa, whereas stepping up to this Ø160 bore provides 10053.1 N at the same pressure, giving you 2050 kgf maximum push at 1.0 MPa. If your end-position never varies, a fixed-stroke ACQ160 cylinder will suffice and saves adjustment time. For ordering, confirm the 160 mm bore, 175 mm full stroke, 75 mm adjuster window, the -S magnet option, and the default female rod thread. Note that a plain compact cylinder will not hold its load on air loss; install an external rod lock or pilot-operated check valve if a fail-safe hold is required.
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 ACQJ160X175-75S 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 175 mm, and the -75 mm window allows the extend stroke to be adjusted down to 100 mm.
An external M36x2.0 threaded stop with a lock nut limits the extend distance without changing the piston area, meaning force remains identical to a standard ACQ. The retract stroke is unaffected. Fixed NBR bumpers decelerate the rod near the end of travel, but the cylinder will not hold its load on air loss—use an external rod lock for fail-safe holding.
