Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 30mm 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 ACQJ160X30-30SB
The ACQJ160X30-30SB is a double-acting, single-rod JIS compact cylinder featuring a 160 mm bore and a 30 mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a 0-30 mm usable adjustment window. The retract stroke remains unaffected, and the M36x2.0 adjuster thread allows precise on-machine end-position tuning without swapping components.
Because the piston area is unchanged, output force is identical to a standard ACQ of this size, yielding 10053.1 N push and 9424.8 N pull at 0.5 MPa. This big-bore variant includes a male M36x1.5 piston rod end for direct load coupling, a PT3/8 port, and an integrated piston magnet compatible with reed or solid-state switches. Fixed NBR elastomer bumpers decelerate the load at each end, operating reliably from -20 to +70 C at 30-500 mm/s.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 30 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 ACQJ160X30-30SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 0-30 mm extend position during heavy press commissioning, tweaking the stroke end on-site without machining new spacers.
Large Welding Fixture Changeover
Adapt the extend stop rapidly when switching between heavy welding fixtures, using the external lock nut to secure the new position.
Pallet Lift Height Tuning
Fine-tune the lift height on large palletizers by shortening the extend stroke up to 30 mm, ensuring precise stops for varying load dimensions.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30SB the Right Cylinder?
Selecting this 160 mm bore actuator yields 10053.1 N push at 0.5 MPa, while scaling down to a 140 mm bore provides 7696.9 N push, and no larger bore exists in this range. A fixed-stroke ACQ cylinder suffices if your extend end position never varies. Confirm your ordering essentials: 160 mm bore, 30 mm full stroke, 30 mm adjustment window, the -S magnet for sensing, and the -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 ACQJ160X30-30SB FAQ
At 0.5 MPa, push force is 10053.1 N and pull force is 9424.8 N; push at 0.7 MPa is 14074.3 N, with a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 30 mm with a 30 mm adjustment window, giving a usable extend range of 0-30 mm. The external adjuster features an M36x2.0 thread.
The adjuster changes only the extend stroke length, not the piston area, so output force remains identical to a standard ACQ of this bore. Fixed NBR elastomer bumpers decelerate the load at stroke ends rather than adjustable air cushions. Note that a plain compact cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
