Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 250mm 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 ACQJ160X250-40S
The AirTAC ACQJ160X250-40S is a double-acting JIS compact cylinder from the big-bore range, featuring a 250 mm full stroke and an external extend stop. A threaded rod-end adjuster with a lock nut lets you set the usable extend range from 210 mm up to 250 mm directly on your machinery. The retract travel remains completely unaffected by this adjustment.
Because the internal piston area stays constant, output force is identical to a standard ACQ of this bore, delivering 10053.1 N push at 0.5 MPa. The body uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. Equipped with a piston magnet (-S), the integrated sensor grooves accept both reed and solid-state electronic switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 250 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 ACQJ160X250-40S Is Used
Automotive Body Welding
Dial in the 210-250 mm extend position on the fly to accommodate varying sheet metal panel thicknesses without machining new stop collars.
Heavy Press Fixturing
Alter the extend end-stop during product changeover to safely position large metal stampings before the press cycle begins.
Palletizing End Effectors
Test and set trial end positions for heavy-load gripper arms on robotic palletizers, ensuring precise placement before final lock-down.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-40S the Right Cylinder?
For 0.5 MPa pneumatic pushing requirements around 7696.9 N, the smaller 140 mm bore variant is the next step down, while this 160 mm bore provides 10053.1 N if your application needs higher thrust. If your end-position never varies, a fixed-stroke ACQ is sufficient, but this ACQJ model is required when setups demand variable extend limits. When ordering, verify the 160 mm bore, 250 mm full stroke, 40 mm window, the -S magnet option, and the default female M24x3.0 rod-end 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 ACQJ160X250-40S FAQ
It provides 10053.1 N push and 9424.8 N pull force 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 250 mm, and the external adjuster allows an extend range of 210-250 mm.
No, the adjuster only limits the extend stroke length, keeping force identical to a standard ACQ. The cylinder uses fixed NBR bumpers, not air cushions. A plain ACQ will drift on air loss, so for fail-safe load holding, install an external rod lock or pilot-operated check valve.
