Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-20SB
The AirTAC ACQJ160X200-20SB is a double-acting JIS compact cylinder from the big-bore range, engineered with a 200mm full stroke and a 20mm external adjustment window. An external threaded stop with a lock nut restricts how far the rod extends, yielding a usable forward travel of 180-200mm. The return journey remains completely unaffected. Because the piston area stays constant, output thrust is identical to a standard ACQ of this size.
This massive actuator delivers 10053.1N of push force at 0.5MPa and accommodates PT3/8 ports. It features a fixed NBR elastomer bumper at each end for deceleration and includes a built-in piston magnet compatible with reed or solid-state switches. The male M36x1.5 rod end couples directly to heavy loads, while the M36x2.0 adjuster thread allows precise end-position tuning without swapping mechanical parts.

| Bore size | Ø160 mm |
| Full stroke | 200 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 ACQJ160X200-20SB Is Used
Heavy Press Positioning
Dial in the exact 180-200mm extend endpoint on heavy stamping presses to accommodate varying material thicknesses without machining new stop collars.
Large Fixture Changeover
Adapt large welding or clamping fixtures rapidly during product changeover by turning the external M36x2.0 adjuster to meet new part dimensions.
Big-Bore Lift Trial Stops
Safely test end positions on heavy lifting platforms by limiting the upward extend stroke, preventing accidental overtravel during setup.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20SB the Right Cylinder?
Selecting this 160mm bore provides 10053.1N push and 9424.8N pull at 0.5MPa. If your application requires less force, stepping down to a 140mm bore yields 7696.9N push, whereas moving up is not available in this standard big-bore compact series. A fixed-stroke ACQ is sufficient if the extend endpoint never varies. Confirm your ordering essentials: 160mm bore, 200mm full stroke, 20mm window, -S magnet, and -B male rod thread. Remember that a plain compact cylinder drifts on air loss; utilize an external rod lock for fail-safe holding.
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 ACQJ160X200-20SB FAQ
At 0.5MPa it provides 10053.1N push and 9424.8N pull force, and 14074.3N push at 0.7MPa. The maximum push is 2050kgf at 1.0MPa. The full stroke is 200mm with a 20mm adjustment window, allowing a usable extend range of 180-200mm.
No, the external M36x2.0 threaded stop only limits the extend length, leaving the piston area and thrust unchanged. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The -S magnet supports reed or solid-state switches.
