Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30S 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 ACQJ160X30-30S
The AirTAC ACQJ160X30-30S is a double-acting JIS compact cylinder from the big-bore range, 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 usable extend range of 0-30 mm. The RETRACT stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force is identical to a standard ACQ of this size.
Delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa, this unit uses a PT3/8 port and a 40 mm rod. It includes fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration rather than adjustable pneumatic cushions. The -S suffix indicates a built-in piston magnet compatible with both reed and electronic solid-state switches via the body's sensor grooves.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30S |
|---|---|
| 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 ACQJ160X30-30S Is Used
Press Tonnage Setup
Dial in the exact extend stop on heavy-duty forming presses during tooling changes, adjusting the 0-30 mm window to accommodate different material thicknesses without swapping cylinders.
Large Assembly Forming
Establish trial end positions for large-component metalworking and riveting fixtures, fine-tuning the extend limit on the machine to find the optimal clamping depth before finalizing hard stops.
Heavy Lifting Platforms
Modify the extend reach on automated heavy-load lifting stations during product family changeovers, using the external lock nut to set precise elevation heights for various pallet sizes.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-30S the Right Cylinder?
Selecting this 160 mm bore provides 10053.1 N push at 0.5 MPa. Stepping down to a 140 mm bore yields 7696.9 N push, while no larger compact bore exists in this range. If your application never requires on-machine end-position tuning, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 30 mm full stroke, the 30 mm adjustable window, the -S magnet option, and the default female M24x3.0 rod-end 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 ACQJ160X30-30S FAQ
This big-bore 160 mm cylinder provides 10053.1 N push and 9424.8 N pull 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 30 mm with a 30 mm adjustable window, allowing a usable extend range of 0-30 mm. The retract stroke is unaffected.
An external M36x2.0 threaded stop with a lock nut mechanically limits the extend distance; it changes stroke length only and does not alter piston area, so force remains identical to a standard ACQ. The cylinder relies on fixed NBR elastomer bumpers for end-of-stroke deceleration, and the -S magnet works with reed or electronic solid-state switches.
