Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20SB 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 ACQJ160X30-20SB
The AirTAC ACQJ160X30-20SB is a double-acting, big-bore JIS compact cylinder featuring an external threaded stop and lock nut that limits the EXTEND end position. With a full stroke of 30mm and a 20mm adjustment window, the usable extend range is 10-30mm. The RETRACT stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This Ø160mm variant delivers 10053.1N of push force at 0.5MPa and includes a male-thread piston rod end (M36x1.5) for direct load coupling. The -S magnet works with reed or electronic solid-state switches, and the fixed NBR elastomer bumper decelerates the load at stroke ends.

| 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 ACQJ160X30-20SB Is Used
Heavy Press Tunning
Dial in the exact 10-30mm extend position during heavy press setup without machining new spacers or changing cylinder bodies.
Large Fixture Changeover
Adapt large automated press stops instantly when swapping heavy product fixtures, utilizing the M36x2.0 external adjuster thread.
Press Trial Positions
Test multiple extend end positions on a new metal-forming line safely, knowing the fixed elastomer bumper handles end deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20SB the Right Cylinder?
When sizing this big-bore compact cylinder, stepping down to the Ø140 bore yields 7696.9N push at 0.5MPa, while the Ø160 provides 10053.1N. If the exact end position is fixed and never varies, a standard ACQ cylinder suffices. For ordering, confirm the 160mm bore, 30mm full stroke, 20mm 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 ACQJ160X30-20SB FAQ
Push force is 10053.1N and pull is 9424.8N at 0.5MPa; push is 14074.3N at 0.7MPa; max push is 2050kgf at 1.0MPa. The usable extend range is 10-30mm (30mm full stroke minus up to a 20mm window). The port is PT3/8, female rod-end thread is M24x3.0, male rod-end thread is M36x1.5, and the external adjuster thread is M36x2.0.
The external threaded stop with a lock nut limits only the extend stroke length, meaning force is identical to a standard ACQ because the piston area is unchanged. The fixed NBR elastomer bumper decelerates the load near stroke end, but a plain ACQ-type does not hold its load on air loss or when a valve is centered; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
