Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-50SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 75mm 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 ACQJ160X75-50SB
The AirTAC ACQJ160X75-50SB is a big-bore JIS compact pneumatic cylinder featuring an external adjustable extend stop. A threaded rod with a lock nut permits you to fine-tune the extend end position directly on your machinery, yielding a usable extend range of 25 to 75 mm. The retract stroke remains completely unaffected by this mechanism. Because the internal piston area stays constant, output force is identical to a standard ACQ of this bore.
This double-acting single-rod unit delivers 10053.1 N of push force and 9424.8 N of pull force at 0.5 MPa. It includes a fixed elastomer NBR bumper at each end for impact deceleration rather than an adjustable air cushion. Equipped with a male piston rod end (M36x1.5) and an integrated magnet, the sensor grooves accept both reed and electronic solid-state switches.

| Bore size | Ø160 mm |
| Full stroke | 75 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 |

| 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 ACQJ160X75-50SB Is Used
Heavy Press Tonnage
Dial in the exact 25 to 75 mm extend position for large metal stamping presses during die setup or material thickness changes.
Pallet Changeover
Modify the extend stop on automated pallet conveyor systems to accommodate different pallet lengths without swapping hardware.
Large Clamp Positioning
Set precise clamping endpoints on heavy machinery, relying on the fixed elastomer bumper to absorb the 14074.3 N force at 0.7 MPa.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-50SB the Right Cylinder?
For applications needing less thrust, the 140mm bore yields 7696.9 N push at 0.5 MPa, whereas this 160mm unit provides 10053.1 N. If your task requires the full 75 mm extend stroke every cycle without variation, a fixed-stroke ACQ is simpler. When ordering, verify the 160mm bore, 75mm full stroke, 50mm adjuster window, along with the -S magnet and -B male rod thread options.
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 ACQJ160X75-50SB FAQ
It delivers 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 75 mm with a 50 mm adjustment window, giving a usable extend range of 25 to 75 mm.
The external M36x2.0 threaded stop with lock nut limits only the extend stroke length, meaning force remains identical to a standard ACQ. A fixed NBR bumper decelerates the load near stroke end, while the integrated -S magnet works with reed or solid-state switches.
