Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30SB 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 ACQJ160X175-30SB
The AirTAC ACQJ160X175-30SB is a double-acting JIS compact cylinder with an adjustable extend stroke. An external M36x2.0 threaded stop and lock nut lets you fine-tune the rod extension on the machine, yielding a usable extend range of 145-175 mm from the 175 mm full stroke. The retract stroke remains unaffected. This big-bore Ø160 unit features a PT3/8 port, a male M36x1.5 rod end, and a built-in magnet.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore: 10053.1 N push and 9424.8 N pull at 0.5 MPa. The cylinder uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, and the magnetic piston is compatible with reed or solid-state switches.

| 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 ACQJ160X175-30SB Is Used
Press Tooling Setup
Dial in the exact clamping extension during press tooling setup without machining custom spacers for varying material thicknesses.
Heavy Fixture Changeover
Adapt heavy-duty assembly line stops instantly during product changeover by turning the external M36x2.0 adjuster to match new part dimensions.
Press Stroke Trials
Establish safe trial end positions on large metal-forming presses by limiting the extend stroke to prevent costly crashes during prototype runs.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30SB the Right Cylinder?
This Ø160 bore generates 10053.1 N push at 0.5 MPa. Stepping down to a Ø140 bore yields 7696.9 N push, while stepping up to a larger custom bore increases force further. Choose this big-bore compact body when you need high thrust within a short machine envelope. If your end position never varies, a fixed-stroke ACQ suffices. Confirm your ordering essentials: 160 mm bore, 175 mm full stroke, -30 mm 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 ACQJ160X175-30SB 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 full stroke is 175 mm with a -30 mm window, giving a usable extend range of 145-175 mm.
The external threaded stop limits only the extend stroke, leaving the retract stroke unaffected. It changes the stroke length only, so the output force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Note that a plain cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for a fail-safe hold.
