Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100S 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 ACQJ40X100-100S
The AirTAC ACQJ40X100-100S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 0 up to 100 mm directly on your equipment without swapping parts, while the retract stroke remains completely unaffected. It includes a built-in magnet (-S) for position sensing.
Because the piston area stays the same, output force equals a standard ACQ of this bore: 628.3 N push and 527.8 N pull at 0.5 MPa. The unit uses a 16 mm rod, an M8x1.25 female rod-end thread, and PT1/8 ports. Fixed elastomer bumpers decelerate the load at each end, and the M12x1.25 adjuster thread provides stable stroke modification.

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 ACQJ40X100-100S Is Used
Machining Fixture Clamps
Dial in the exact clamping extension on a CNC fixture during part-changeover without machining new stop spacers.
Packaging Forming Stops
Adjust the extend position on a carton forming machine to handle different box heights rapidly on the fly.
Assembly Press Positions
Set precise trial end positions for pressing bearings, allowing quick retraction if the fit depth needs tweaking.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100S the Right Cylinder?
Choosing this 40 mm bore gives 628.3 N push at 0.5 MPa. If you need less force, the 32 mm bore yields 402.1 N push, or for heavier tasks, the 50 mm bore provides 981.8 N. A fixed-stroke ACQ works fine if your end position never varies. When ordering, confirm the 100 mm full stroke, the 100 mm adjustment window, the -S magnet, and the M8x1.25 female 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 ACQJ40X100-100S 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, and with the 100 mm window, the usable extend range is 0-100 mm.
The M12x1.25 external stop only changes the extend stroke length; it does not alter piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers handle end deceleration, and the -S magnet works with reed or electronic solid-state switches.
