Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-10B 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 ACQJ40X100-10B
The AirTAC ACQJ40X100-10B is a double-acting JIS compact cylinder with a male-thread piston rod end (M14x1.5) that couples directly to your load. An external M12x1.25 threaded stop and lock nut limits the extend end position, providing a usable extend range of 90-100 mm from the 100 mm full stroke. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, 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 features fixed elastomer NBR bumpers at each end rather than adjustable air cushions, and includes sensor grooves for adding reed or solid-state switches, though this specific unit 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 |

| 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 ACQJ40X100-10B Is Used
Machining Fixture Clamps
Dial in the exact 90-100 mm clamping reach on a CNC lathe during setup, allowing operators to compensate for varying raw material thicknesses without swapping cylinders.
Carton Forming Stops
Adjust the extend end position on the fly during packaging line changeovers to accommodate different box depths, ensuring precise folding and sealing contact.
Assembly Press Positioning
Establish trial end positions for pressing bearings on an automated assembly line, fine-tuning the 10 mm window to prevent over-travel and part damage.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-10B the Right Cylinder?
If you need slightly less thrust, stepping down to a 32 mm bore yields 402.1 N push at 0.5 MPa, while moving up to a 50 mm bore provides 981.8 N. Choose this 40 mm model when your application requires approximately 628 N of push force and precise 90-100 mm extend positioning. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 40 mm bore, 100 mm full stroke, 10 mm adjuster window, the male B rod thread, and whether you need the S magnet option for sensing.
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 ACQJ40X100-10B FAQ
The usable extend range is 90-100 mm, created by the 10 mm adjustment window on the 100 mm full stroke. Force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the extend length without changing piston area, so force remains unchanged and the retract stroke is unaffected. The cylinder uses fixed elastomer bumpers, not adjustable cushions. Note that a plain ACQ-type does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
