Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 100mm 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 ACQJ40X100-30
The ACQJ40X100-30 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend end position. You can fine-tune the forward stroke on the machine itself, yielding a usable extend range of 70-100 mm from the 100 mm full stroke, while the retract stroke remains completely unaffected. A PT1/8 port and 16 mm piston rod drive 628.3 N of push force at 0.5 MPa.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 527.8 N of pull at 0.5 MPa and 879.6 N of push at 0.7 MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Body sensor grooves are built-in, though this specific configuration ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 100 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ40X100-30 Is Used
Machining Fixture Clamping
Dial in the exact clamping extension on a CNC fixture during part-changeover without machining new stop collars, utilizing the 70-100 mm usable forward travel.
Carton Sealing Formers
Adjust the folding arm end-position on the fly for varying package heights, relying on the 628.3 N push force to hold cartons securely.
Assembly Press Stops
Set trial end positions for pressing sub-components, safely decelerating the tooling against the fixed elastomer bumper at the stroke limit.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30 the Right Cylinder?
Selecting this 40 mm bore provides a strong mid-range option, stepping up from the 32 mm bore (402.1 N push @0.5 MPa) or stepping down from the 50 mm bore (981.8 N push @0.5 MPa). If your application never requires altering the end position, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 100 mm full stroke, the 30 mm adjustment window, the default female M8x1.25 rod-end thread, and note that the -S magnet option is omitted here.
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 ACQJ40X100-30 FAQ
It delivers 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 100 mm with a 30 mm adjustment window, giving a usable extend range of 70-100 mm.
An external M12x1.25 threaded adjuster with a lock nut limits the forward extension, changing the stroke length only. The force remains identical to a standard ACQ because the piston area is unchanged. The retract stroke is unaffected, and end-deceleration is handled by a fixed elastomer bumper, not an adjustable cushion.
