Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-20SB
The AirTAC ACQJ160X150-20SB is a double-acting, single-rod JIS compact cylinder engineered for big-bore applications. It features an external threaded stop with a lock nut on the extend side, allowing you to fine-tune the extend end position directly on your equipment. With a full stroke of 150 mm and a 20 mm adjustment window, the usable extend range spans 130 to 150 mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 10053.1 N of push force at 0.5 MPa. This model includes a male-thread piston rod end (M36x1.5) for direct load coupling and a built-in piston magnet (-S) compatible with reed or electronic solid-state switches. It utilizes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| 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 ACQJ160X150-20SB Is Used
Heavy Press Tonnage Tuning
Dial in the exact 130-150 mm extend position on a heavy-duty stamping press without machining custom spacers during initial tooling setup.
Large Fixture Changeover
Shift the extend stop rapidly when swapping large machined product families on an automated heavy-machinery assembly line.
Press Fit Depth Control
Establish precise downward travel limits for pressing large bearings or pins, testing various insertion depths without altering pneumatic plumbing.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-20SB the Right Cylinder?
When sizing this 160 mm bore unit, consider the neighboring bores: the 140 mm bore yields 7696.9 N push at 0.5 MPa, whereas the 160 mm bore provides 10053.1 N push at 0.5 MPa, ensuring you have the necessary thrust for heavy loads. If your end position never varies, a fixed-stroke ACQ cylinder will suffice. To order this adjustable version, confirm the 160 mm bore, 150 mm full stroke, 20 mm window, the -S magnet requirement, 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 ACQJ160X150-20SB FAQ
This cylinder provides 10053.1 N push and 9424.8 N pull force 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 150 mm with a 20 mm adjustable window, yielding a usable extend range of 130-150 mm.
The external M36x2.0 threaded stop with a lock nut limits only the extend stroke length; it does not alter the piston area, so force remains identical to a standard ACQ. The fixed elastomer bumper decelerates the rod near stroke end, but a plain cylinder will not hold a load on air loss—use an external rod lock or pilot-operated check valve for fail-safe holding.
