Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 100mm 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 ACQJ160X100-75SB
The ACQJ160X100-75SB is a double-acting JIS compact cylinder featuring a big 160 mm bore and an external extend stop. A threaded rod with a lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 25 to 100 mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays the same, force output is identical to a standard ACQ of this bore.
This variant includes a male M36x1.5 piston rod end for direct load coupling and an integrated piston magnet for electronic or reed sensing. It uses a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 port handles high flow requirements.

| Bore size | Ø160 mm |
| Full stroke | 100 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 ACQJ160X100-75SB Is Used
Heavy Press Tooling
Dial in the exact extend stop during press tooling setups to accommodate varying material thicknesses without machining new spacers.
Automotive Assembly Jigs
Shift the extend end position rapidly during vehicle model changeovers on the line, using the 25 to 100 mm window to set new fixture limits.
Palletizing Stops
Adjust the extend stroke on the fly to handle different pallet sizes or product widths, relying on the 160 mm bore for high-force positioning.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75SB the Right Cylinder?
Choosing this 160 mm bore yields a theoretical push of 10053.1 N at 0.5 MPa and a maximum push of 2050 kgf at 1.0 MPa. If your application needs less force, stepping down to the 140 mm bore provides 7696.9 N push at 0.5 MPa. A standard fixed-stroke ACQ is sufficient if your end position never varies. Confirm your ordering essentials: 160 mm bore, 100 mm full stroke, 75 mm adjuster window, 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 ACQJ160X100-75SB FAQ
At 0.5 MPa it provides 10053.1 N push and 9424.8 N pull, and 14074.3 N push at 0.7 MPa. The maximum push is 2050 kgf at 1.0 MPa. The 75 mm adjustable window allows a usable extend range of 25 to 100 mm.
The external M36x2.0 threaded stop with a lock nut limits the extend stroke length only, meaning force is unchanged from a standard ACQ. The cylinder uses fixed elastomer bumpers, not adjustable cushions. A plain cylinder will not hold a load on air loss, so use an external rod lock for fail-safe holding.
