Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 20mm 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 ACQJ160X20-10S
The ACQJ160X20-10S is a big-bore JIS compact cylinder engineered for double-acting operation with an external extend stop. An M36x2.0 threaded adjuster and lock nut restrict how far the rod travels outward, yielding a usable extend span of 10 to 20 mm from the 20 mm full stroke. Retract movement remains at the standard 20 mm. Because the piston area stays constant, output force equals that of a regular ACQ, giving 10053.1 N push and 9424.8 N pull at 0.5 MPa.
This heavy-duty variant features a 40 mm piston rod, PT3/8 porting, and a female M24x3.0 rod-end thread. Deceleration relies on a fixed NBR elastomer bumper at each end rather than adjustable pneumatic cushioning. Equipped with a piston magnet (-S), the body accepts both reed and solid-state electronic switches for position detection. Note that a plain compact cylinder drifts on air loss; install an external rod lock for fail-safe load holding.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 20 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 ACQJ160X20-10S Is Used
Press Tonnage Setup
Dial in the exact 10 to 20 mm extend reach on a heavy metal stamping press to accommodate different die heights during product changeover.
Heavy Fixture Clamping
Securely grip large castings by tweaking the outward stop on the machine without machining custom spacer rings for each part.
Assembly Stroke Trials
Test multiple end positions for a 10053.1 N pressing action in automotive assembly lines before locking the final downward travel distance.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10S the Right Cylinder?
Choosing this 160 mm bore provides a maximum push of 2050 kgf at 1.0 MPa. If your application requires less force, the neighboring 140 mm bore yields 7696.9 N push at 0.5 MPa, while stepping up is not applicable as this is the largest standard size. If your end position never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering, confirm the 20 mm full stroke, 10 mm 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 ACQJ160X20-10S 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 20 mm full stroke features a 10 mm adjustable window, allowing an extend range of 10 to 20 mm.
The M36x2.0 threaded stop limits only the extend length, leaving force unchanged from a standard ACQ. Deceleration relies on a fixed NBR bumper, not an adjustable air cushion. For high-speed loads, add an external shock absorber, and use an external rod lock for fail-safe holding.
