Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 50mm 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 ACQJ160X50-40SB
The ACQJ160X50-40SB is a double-acting JIS compact cylinder featuring a 160mm bore and an external extend-stroke adjuster. By turning the M36x2.0 threaded stop with its lock nut, you can fine-tune the forward end position on the machine, yielding a usable extend range of 10-50mm. The retract stroke remains completely unaffected by this adjustment.
Delivering identical force to a standard ACQ of this size, it outputs 10053.1N push and 9424.8N pull at 0.5 MPa. This big-bore variant includes a male M36x1.5 piston rod end for direct load coupling, a built-in magnet for electronic or reed sensors, and fixed NBR elastomer bumpers. Note that a plain cylinder drifts on air loss; use an external rod lock for fail-safe load holding.

| 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 ACQJ160X50-40SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 10-50mm extend reach on a multi-ton metalforming press during initial tooling setup, preventing over-travel without machining custom spacers.
Large Fixture Changeover
Adapt a massive machining clamping fixture for new part families by tweaking the external M36x2.0 stop, accommodating varying workpiece widths rapidly on the fly.
Heavy Lift Positioning
Establish trial end positions for a large automated lifting platform, allowing operators to safely limit the 14074.3N @0.7MPa push force before finalizing the mechanical hard stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40SB the Right Cylinder?
Selecting this 160mm bore provides massive thrust in a compact footprint. If 9424.8N pull at 0.5 MPa is excessive, dropping to a 140mm bore yields 7696.9N push, whereas no larger standard ACQJ bore exists. A fixed-stroke ACQ suffices if your extend endpoint never requires variation. Confirm ordering essentials: 160mm bore, 50mm full stroke, 40mm adjuster window, the -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 ACQJ160X50-40SB FAQ
At 0.5 MPa, this 160mm bore cylinder provides 10053.1N push and 9424.8N pull, with a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 50mm, and with the 40mm adjustment window, the usable extend range is 10-50mm.
An external M36x2.0 threaded stop and lock nut mechanically limits the forward stroke length, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
