Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 50mm 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 ACQJ160X50-20S
The AirTAC ACQJ160X50-20S is a big-bore JIS compact pneumatic cylinder featuring a double-acting single rod and an external extend-stop mechanism. A threaded adjuster with a lock nut lets you set the forward end position on the machine itself, yielding a usable forward travel span of 30-50 mm from the 50 mm full stroke. The return stroke remains completely unaffected by this adjustment.
Because the piston dimensions stay the same, output force equals a standard ACQ of this size, delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa. This Ø160 mm unit uses a 40 mm rod, PT3/8 ports, and a fixed NBR elastomer bumper at each end to decelerate the load. The -S suffix indicates a built-in piston magnet compatible with both reed and solid-state electronic switches.

| Bore size | Ø160 mm |
| Full stroke | 50 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 |

| 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 ACQJ160X50-20S Is Used
Press Tonnage Setup
Dial in the exact 30-50 mm extend position during heavy press setup without machining custom spacers for each new die height.
Heavy Fixture Changeover
Adapt large welding or clamping fixtures rapidly on the plant floor by turning the external M36x2.0 adjuster to shift the forward stop.
Lift Station Calibration
Test and set precise trial end positions for heavy lifting stations, ensuring the 9424.8 N pull force operates safely across the adjusted range.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-20S the Right Cylinder?
If your setup requires less thrust, the adjacent Ø140 bore yields 7696.9 N push at 0.5 MPa, whereas stepping up is not available since 160 mm is the largest big-bore compact option in this range. A standard fixed-stroke ACQ cylinder suffices if your end position never needs tweaking. When ordering, confirm the 160 mm bore, 50 mm full stroke, 20 mm adjust window, -S magnet, 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 ACQJ160X50-20S FAQ
It delivers 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 50 mm with a 20 mm adjustment window, allowing a usable extend range of 30-50 mm.
The external M36x2.0 threaded stop with lock nut limits only the extend length, leaving the retract stroke untouched and keeping force identical to a standard ACQ. Deceleration relies on a fixed NBR bumper, not an adjustable air cushion; for fail-safe load holding on air loss, install an external rod lock or pilot-operated check valve.
