Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X100-40S
The AirTAC ACQJ32X100-40S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to precisely limit the extend stroke. You can tune the usable extend range from 60 mm up to the full 100 mm on the machine without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. It includes a built-in magnet (-S) compatible with reed or solid-state electronic switches, fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and a PT1/8 port. The external adjuster uses an M12x1.25 thread.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X100-40S Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture during new product introduction without machining custom spacers.
Packaging Changeover
Rapidly adjust the pusher end position on a packaging line when switching between different carton widths.
Prototype Positioning
Find the optimal trial extension distance on a test rig by threading the stop in or out until the kinematic timing is perfect.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40S the Right Cylinder?
Choosing this 32 mm bore gives 402.1 N push at 0.5 MPa. If your application requires less force, stepping down to a 25 mm bore yields 245.4 N push, while moving up to a 40 mm bore provides 628.3 N push. A fixed-stroke ACQ is sufficient if your end position never varies, but this ACQJ variant is essential for setups requiring frequent end-position tuning. When ordering, verify the 100 mm full stroke, the 40 mm adjustable window, the -S magnet option, and the default female M8x1.25 rod-end 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 ACQJ32X100-40S FAQ
Force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 60-100 mm, meaning the 40 mm window allows you to shorten the 100 mm full stroke by up to 40 mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends. This changes the stroke length only, not the piston area, so force remains unchanged. The retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions.
