About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-50S
The AirTAC ACQJ160X200-50S is a double-acting, single-rod JIS compact cylinder from the big-bore range, featuring a 200mm full stroke and an external threaded stop with a lock nut. This adjuster allows you to fine-tune the extend end position on the machine, yielding a usable extend range of 150-200mm without changing parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 10053.1N push at 0.5MPa. The unit features a 40mm rod, PT3/8 porting, and a fixed NBR elastomer bumper at each end. An integrated piston magnet (-S) enables position sensing with reed or solid-state switches.

| 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 ACQJ160X200-50S Is Used
Heavy Press Tonnage Setup
Dial in the exact 150-200mm extend position during heavy press commissioning to accommodate varying material thicknesses without machining custom spacers.
Automotive Fixture Changeover
Adapt large body-panel forming stops rapidly on the production line when switching between vehicle models, relying on the 2050kgf clamping force.
Palletizer End-of-Arm Tooling
Tune the pusher stroke on packaging machinery to handle different pallet sizes, utilizing the fixed elastomer bumper to absorb high kinetic energy.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-50S the Right Cylinder?
When sizing this 160mm bore actuator, a 140mm variant provides 7696.9N push @0.5MPa, while no larger standard ACQJ bore exists, making this the top force option (2050kgf max push @1.0MPa). If your extend distance never varies, a fixed-stroke ACQ cylinder suffices; choose the ACQJ when setups require frequent end-position adjustments. Confirm ordering essentials: 160mm bore, 200mm full stroke, 50mm adjust window, -S magnet, and female M24x3.0 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 ACQJ160X200-50S FAQ
It delivers 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and 2050kgf max push at 1.0MPa. The external adjuster has an M36x2.0 thread. The usable extend range is 150-200mm (200mm full stroke minus the 50mm window).
No, the external stop limits only the extend length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end; for high-speed loads, add an external shock absorber. Note that a plain ACQ does not hold loads on air loss, so use an external rod lock for fail-safe holding.
