Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-40S
The ACQJ160X200-40S is a double-acting JIS compact cylinder featuring a 160mm bore and a 200mm full stroke. An external threaded stop with a lock nut permits on-machine extend end-position tuning. You can shorten the forward stroke by up to 40mm, yielding a usable extend range of 160 to 200mm. The retract movement remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of this size, delivering 10053.1N push and 9424.8N pull at 0.5MPa. This big-bore unit includes a 40mm rod, an M24x3.0 female rod-end thread, and PT3/8 ports. Fixed NBR elastomer bumpers absorb impact at both ends, while the built-in magnet (-S) supports reed or solid-state sensors.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 200 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 ACQJ160X200-40S Is Used
Heavy Press Positioning
Dial in the exact 160-200mm extend reach on a large stamping press during setup, avoiding custom spacer machining when material thickness varies.
Product Changeover Stops
Quickly alter the forward endpoint on an automotive assembly line fixture to accommodate new model dimensions without swapping the actuator body.
Pallet Lift Height Tuning
Fine-tune the lifting height on a heavy-duty palletizer by adjusting the extend stop, ensuring precise leveling for different pallet footprints.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40S the Right Cylinder?
When sizing this 160mm bore actuator, dropping down to a 125mm bore reduces 0.5MPa push force to 6135.9N, whereas stepping up is outside standard compact ranges. If your machine never requires stroke length changes, a fixed ACQ cylinder provides identical thrust without the external hardware. To order this adjustable version, confirm the 200mm full stroke, the 40mm window, the -S magnet, and your required rod-end thread type.
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 ACQJ160X200-40S FAQ
This 160mm bore cylinder provides 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. The 40mm adjustment window allows a usable extend range of 160 to 200mm.
The M36x2.0 external threaded stop limits only the extend length, leaving retract unchanged; piston area remains the same, so thrust matches a standard ACQ. Fixed elastomer bumpers decelerate the rod near stroke end, but a plain cylinder drifts on air loss, so use an external rod lock for fail-safe load holding.
