Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-50S 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 ACQJ160X250-50S
The ACQJ160X250-50S is a big-bore JIS compact pneumatic cylinder featuring a 160 mm bore and a 250 mm 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 50 mm, yielding a usable extension range of 200 to 250 mm. The retract distance remains completely unaffected by this adjustment.
Because the internal piston area stays the same, output force is identical to a standard ACQ of this size. At 0.5 MPa it delivers 10053.1 N of push force and 9424.8 N of pull force. The unit incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration and includes a built-in magnet for electronic or reed switch detection.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-50S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-50S |
|---|---|
| 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 ACQJ160X250-50S Is Used
Press Tooling Changeover
Accommodate varying die heights during production line changeovers by dialing the extend stop back within the 200 to 250 mm window without machining new spacers.
Heavy Fixture Positioning
Set precise clamping endpoints for oversized welding fixtures, relying on the 10053.1 N thrust to secure heavy assemblies while fine-tuning the final contact point.
Stamping Depth Trials
Run test strokes on a forming press to establish the exact material deformation depth, using the external M36x2.0 adjuster to dial in the exact 200-250 mm extension.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-50S the Right Cylinder?
When sizing this big-bore variant, consider the adjacent bore options. Dropping down to a 140 mm bore yields 7696.9 N push at 0.5 MPa, while stepping up to the 160 mm bore provides 10053.1 N. If your application never requires altering the forward end position, a fixed-stroke ACQ cylinder will provide the same thrust in a simpler package. To order, confirm the 160 mm bore, 250 mm full stroke, 50 mm adjustable window, the S magnet option, and the 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 ACQJ160X250-50S 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 250 mm with a 50 mm adjustment window, giving a usable extend range of 200-250 mm.
The adjuster only changes the extend length, leaving thrust identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The S magnet supports reed or solid-state switches.
