Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 40mm 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 ACQJ160X40-40SB
The AirTAC ACQJ160X40-40SB is a double-acting JIS compact cylinder from the big-bore range, featuring a 40mm piston rod and an external extend stop. A threaded adjuster with a lock nut lets you set the extend end position from 0 to 40mm directly on your machinery, while the retract stroke remains completely unaffected. Because the piston area stays constant, output force is identical to a standard ACQ of this size.
This massive unit delivers 10053.1N of push force at 0.5 MPa and handles a maximum push of 2050 kgf at 1.0 MPa. It includes a male M36x1.5 rod end for direct load coupling, PT3/8 ports, and fixed NBR elastomer bumpers at both ends. The built-in magnet (-S) supports both reed and solid-state sensors, operating reliably between -20 and +70 C.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 40 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 ACQJ160X40-40SB Is Used
Heavy Press Setup
Dial in the exact 0-40mm extend reach on a large metal stamping press during initial tooling setup without machining new spacers.
Product Changeover
Quickly adjust the extend endpoint on a heavy-duty packaging line when switching between different large pallet sizes.
Trial End Positions
Test varying clamping depths on automotive assembly fixtures to find the optimal reach before finalizing the mechanical stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40SB the Right Cylinder?
Selecting this 160mm bore provides 10053.1N push at 0.5 MPa; dropping to a 140mm bore reduces push to 7696.9N, while stepping up is impossible as 160mm is the largest big-bore option. If your equipment never requires end-position tuning, a fixed-stroke ACQ cylinder will deliver the exact same power. When ordering, confirm the 40mm full stroke, 40mm adjustment 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 ACQJ160X40-40SB FAQ
It provides 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The usable extend range is 0-40mm, created by a 40mm full stroke minus a 40mm adjustment window.
An M36x2.0 external threaded screw with a lock nut limits the extend length without changing piston area, so force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the rod near stroke ends, but a plain cylinder will drift on air loss, requiring an external rod lock for fail-safe holding.
