Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40 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 ACQJ40X100-40
The AirTAC ACQJ40X100-40 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 60 mm up to the full 100 mm directly on your machine without swapping parts. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays the same, 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. It features a 16 mm piston rod, an M8x1.25 female rod-end thread, and a PT1/8 port. The body incorporates fixed elastomer bumpers at both ends and includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| 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 ACQJ40X100-40 Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture to accommodate varying raw part sizes without manufacturing new stop collars.
Product Changeover
Rapidly adapt the extend end position on packaging equipment during format changes, utilizing the M12x1.25 adjuster to set the new stroke limit.
Assembly Press Positioning
Establish precise trial end positions for pressing sub-components, allowing operators to tweak the 60-100 mm range on the line to perfect the insertion depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40 the Right Cylinder?
When sizing this unit, consider the neighbouring bores: a 32 mm bore provides 402.1 N push at 0.5 MPa, while a 50 mm bore yields 981.8 N. If your application never requires end-position adjustments, a fixed-stroke ACQ40X100 will suffice and saves setup time. For ordering, confirm the 40 mm bore, 100 mm full stroke, 40 mm adjuster window, female rod thread, and whether you need the -S magnet option for sensors.
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 ACQJ40X100-40 FAQ
The usable extend range is 60-100 mm (a 100 mm full stroke minus up to a 40 mm window). 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 retract stroke remains the full 100 mm.
No, the adjuster changes the stroke length only, so the force is identical to a standard ACQ40 cylinder. The unit uses fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions. Note that this model ships without a magnet, though the body retains sensor grooves for adding reed or solid-state switches if needed.
