Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40SB 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 ACQJ160X175-40SB
The AirTAC ACQJ160X175-40SB is a double-acting, single-rod JIS compact cylinder from the big-bore range, capable of standard strokes up to 300mm. It features an external threaded stop with a lock nut on the extend side, allowing you to fine-tune the end position directly on the machine. The usable extend range spans 135 to 175mm, as the 40mm adjustment window simply shortens the forward travel. The retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore. At 0.5MPa it provides 10053.1N of push force and 9424.8N of pull force, peaking at a maximum push of 2050kgf at 1.0MPa. This unit includes a male M36x1.5 rod end (-B) for direct load coupling, a built-in magnet (-S) for electronic or reed switches, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40SB |
|---|---|
| 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 ACQJ160X175-40SB Is Used
Heavy Press Fixture Tuning
Dial in the exact clamp depth on large metal-forming presses during setup, testing different material thicknesses without swapping out the entire cylinder.
Automated Welding Line Changeover
Adjust the extend stroke for varying automotive chassis dimensions on the fly, enabling rapid product changeover without disassembling the station.
Bending Machine Trial Stops
Set precise trial end positions for heavy-duty bending operations, allowing operators to fine-tune the bend angle by shortening the forward travel up to 40mm.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40SB the Right Cylinder?
When sizing this big-bore 160mm unit, stepping down to a 140mm bore drops the 0.5MPa push force to 7696.9N, while stepping up to the maximum 160mm bore provides 10053.1N. A fixed-stroke ACQ is sufficient if your extend end position never requires tweaking. Confirm your ordering essentials: 160mm bore, 175mm full stroke, 40mm window, -S magnet, and -B male rod thread. Note that a plain ACQ-type cylinder does not hold its load on air loss; for fail-safe holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ160X175-40SB FAQ
The usable extend range is 135-175mm (a 40mm window subtracted from the 175mm full stroke). Force is identical to a standard ACQ: it delivers 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa.
An external M36x2.0 threaded stop with a lock nut limits forward travel, shortening the extend stroke only; the retract stroke remains unaffected. Because the piston area stays the same, force is unchanged. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration, not adjustable air cushions.
