Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 35mm 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 ACQJ40X35-10B
The AirTAC ACQJ40X35-10B is a double-acting JIS compact cylinder featuring an external male-thread rod end (M14x1.5) that couples directly to your load. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 25 to 35 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The body incorporates sensor grooves for magnetic switches, though this specific configuration ships without a magnet. Deceleration is handled by a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| 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 |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ40X35-10B Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC machining fixture, allowing operators to compensate for varying part thicknesses without swapping out the cylinder.
Packaging Diverter Stroke
Adjust the extend stop on a packaging line diverter to accommodate different carton sizes on the fly, ensuring precise routing without mechanical rebuilds.
Assembly Press Positioning
Fine-tune the trial end position for a light-duty assembly press, tweaking the 25 to 35 mm extend range to avoid over-travel on delicate components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10B the Right Cylinder?
If you need slightly less thrust, the adjacent ACQJ32 bore yields 402.1 N push at 0.5 MPa, whereas stepping up to the ACQJ50 bore provides 981.8 N push. Choose this 40 mm bore when your application requires roughly 628 N of push force and on-machine extend tuning within a 10 mm window. If the exact 35 mm extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 40 mm bore, 35 mm full stroke, 10 mm adjustment window, the male rod thread (-B), and note that no magnet (-S) is included.
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 ACQJ40X35-10B FAQ
This cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 35 mm, and with the 10 mm adjustment window, the usable extend range is 25 to 35 mm.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length only. It does not change the piston area, so the force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for deceleration, and because it lacks a magnet, it will not trigger reed or solid-state switches.
