Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20S 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 ACQJ160X200-20S
The AirTAC ACQJ160X200-20S is a double-acting, single-rod JIS compact cylinder featuring an external extend stop. A threaded adjuster with a lock nut limits the outward stroke, providing a usable extend range of 180 to 200 mm. The retract stroke remains completely unaffected. Because the piston area stays constant, output force is identical to a standard ACQ of this bore. The unit includes a built-in magnet (-S) for position sensing.
This big-bore variant delivers a push force of 10053.1 N and a pull force of 9424.8 N at 0.5 MPa. It features a 40 mm piston rod, a PT3/8 port, and a female M24x3.0 rod-end thread. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. The external M36x2.0 adjuster thread allows on-machine end-position tuning without swapping parts.

| 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 ACQJ160X200-20S Is Used
Heavy Press Tonnage Setup
Dial in the exact 180 to 200 mm extend position during heavy press machine commissioning without machining new stop collars.
Large Fixture Changeover
Adapt end stops quickly on large machining fixtures when switching between product families of varying heights.
Clamping Depth Trials
Test and set precise clamping depths on bulky automotive components before finalizing the mechanical hard stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-20S the Right Cylinder?
Select this 160 mm bore when your setup requires massive thrust (up to 2050 kgf max push at 1.0 MPa) alongside precise extend positioning. If your application only needs a fixed 200 mm stroke, a standard ACQ160X200 cylinder is sufficient. For slightly lower force requirements, the 140 mm bore provides 7696.9 N push at 0.5 MPa. When ordering, confirm the 200 mm full stroke, 20 mm adjustable window, S magnet option, 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 ACQJ160X200-20S FAQ
The usable extend range is 180 to 200 mm (full 200 mm minus a 20 mm window). Force is identical to a standard ACQ: push is 10053.1 N and pull is 9424.8 N at 0.5 MPa, push is 14074.3 N at 0.7 MPa, and maximum push is 2050 kgf at 1.0 MPa. The retract stroke is unaffected.
An external M36x2.0 threaded stop with a lock nut limits the extend stroke only; it changes stroke length, not force. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. A plain ACQ-type does not hold its load on air loss, so for a fail-safe hold you should add an external rod lock or pilot-operated check valve.
