Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 75mm 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 ACQJ160X75-40SB
The AirTAC ACQJ160X75-40SB represents a big-bore JIS compact cylinder featuring a double-acting single rod and an external extend stop. A threaded adjuster with a lock nut lets you set the extend stroke anywhere from 35 to 75 mm, while the retract stroke remains completely unaffected. This on-machine tuning eliminates the need to swap physical parts when adapting to new product dimensions.
Because the piston area stays constant, output force is identical to a standard ACQ of this size, delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit includes a male M36x1.5 piston rod end for direct load coupling, PT3/8 ports, and an NBR elastomer bumper at each end. The built-in magnet (-S) supports reed or solid-state sensing, and the adjuster utilizes an M36x2.0 thread. Note that a plain compact cylinder will drift on air loss; use an external rod lock for fail-safe holding.

| 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 ACQJ160X75-40SB Is Used
Heavy Press Changeovers
Adapt large metal-forming presses to new material thicknesses by dialing in the 35 to 75 mm extend position rapidly without machining new spacers.
Automated Assembly Stops
Set precise end-of-stroke stops for large automotive subassembly fixtures, allowing operators to tweak clamping depth during prototype runs.
Pallet Positioning
Fine-tune the extend limit on heavy-duty palletizing robots to accommodate varying box sizes while maintaining a massive 2050 kgf max push.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-40SB the Right Cylinder?
Choosing this 160 mm bore yields 10053.1 N push at 0.5 MPa. If you need less power, the 140 mm bore provides 7696.9 N push, whereas stepping up is not possible as this is the largest big-bore option. A fixed-stroke ACQ is adequate if your end position never changes. When ordering, verify the 75 mm full stroke, the 40 mm adjustable window, the -S magnet, and the -B male M36x1.5 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 ACQJ160X75-40SB FAQ
At 0.5 MPa, push force is 10053.1 N and pull is 9424.8 N; at 0.7 MPa, push is 14074.3 N. Maximum push is 2050 kgf at 1.0 MPa. The full stroke is 75 mm with a 40 mm adjustable window, yielding a usable extend range of 35 to 75 mm. The retract stroke is unaffected.
The external M36x2.0 threaded stop with lock nut limits only the extend length, meaning force remains identical to a standard ACQ since piston area is unchanged. Deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion. For high kinetic energy loads, add an external shock absorber, and use a pilot-operated check valve or rod lock for fail-safe holding.
