Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 300mm 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 ACQJ160X300-100SB
The ACQJ160X300-100SB is a double-acting, single-rod JIS compact cylinder engineered for big-bore applications requiring up to 300mm of travel. An external threaded stop with a lock nut limits the extend end position, giving you a usable forward range of 200-300mm without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force matches a standard ACQ exactly: 10053.1N push and 9424.8N pull at 0.5MPa. This SB configuration includes a male M36x1.5 rod end for direct load coupling and a piston magnet for solid-state or reed sensors. Deceleration relies on fixed NBR elastomer bumpers, so consider external shock absorbers for high-energy cycles.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 300 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 ACQJ160X300-100SB Is Used
Heavy Press Tonnage
Dialing in the exact extend stop on a multi-ton metal forming press to accommodate varying material thicknesses without reprogramming the machine cycle.
Large Lift Platforms
Setting precise upper travel limits on heavy-duty pneumatic lifting tables where the load height changes frequently between production runs.
Automated Tooling Changeover
Adjusting the extend endpoint during rapid product changeovers on large automotive assembly rigs to test new end positions safely.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-100SB the Right Cylinder?
Selecting this 160mm bore provides massive thrust up to 2050kgf at 1.0MPa. If 9424.8N pull at 0.5MPa is excessive, stepping down to a 140mm bore yields 7696.9N push and 7294.8N pull. Conversely, if your fixture needs more power, no larger standard ACQJ bore exists. Choose this adjustable model only if your setup requires on-the-fly end-position tuning; otherwise, a fixed-stroke ACQ avoids the external adjuster protrusion. Confirm your requirements for the 300mm full stroke, 100mm 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 ACQJ160X300-100SB FAQ
It delivers 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The full stroke is 300mm with a 100mm adjustable window, allowing the extend range to be fine-tuned between 200mm and 300mm.
The M36x2.0 external adjuster acts as a mechanical stop to shorten the extend stroke without changing the output force. Fixed NBR bumpers handle end-of-stroke deceleration instead of air cushions. Note that this cylinder will not hold a load on air loss; install an external rod lock or pilot-operated check valve for fail-safe positioning.
