Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB
The AirTAC ACQJ40X60-40SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND stroke. You get a usable extend range of 20 to 60 mm, as the 40 mm adjustment window shortens the full 60 mm travel. The RETRACT stroke remains completely unaffected by this mechanism.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, yielding 628.3 N of push at 0.5 MPa. This bore uses a 16 mm rod, PT1/8 porting, and includes the -S magnet for reed or solid-state switches alongside the -B male M14x1.5 rod end for direct load coupling.

| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Rod thread | M8×1.25 (F) / M14×1.5 (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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB Is Used
Machining Fixture Stops
Dial in the exact clamping distance on a CNC machining fixture during product-changeover without machining new stop collars.
Carton Sealing Turrets
Set the precise extend position for folding carton flaps on a packaging line, accommodating varying box heights rapidly.
Bending Press Setup
Establish trial end positions for a metal bending press to find the correct angle before finalizing the mechanical stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB the Right Cylinder?
If you need less force, the 32 mm bore delivers 402.1 N push at 0.5 MPa, while the larger 50 mm bore offers 981.8 N if your load requires more push. Choose this 40 mm bore if your application demands roughly 628 N of push force alongside a 20-60 mm variable extend position. A fixed-stroke ACQ suffices if the end position never changes, but this ACQJ variant is essential for setups requiring on-the-fly adjustments. Verify your ordering code includes the 40 mm bore, 60 mm full stroke, 40 mm window, -S magnet, and -B male 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40SB FAQ
The usable extend range is 20 to 60 mm (a 40 mm window subtracted from the 60 mm full stroke). Force is identical to a standard ACQ: push is 628.3 N and pull is 527.8 N at 0.5 MPa, push is 879.6 N at 0.7 MPa, and maximum push is 128 kgf at 1.0 MPa.
No, the M12x1.25 external threaded stop only changes the extend stroke length, leaving force unchanged. Deceleration relies on fixed NBR elastomer bumpers at each end, not an adjustable air cushion. For fail-safe load holding on air loss, add an external rod lock.
