Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm 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 ACQJ32X90-10
The AirTAC ACQJ32X90-10 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to limit the extend end position. You get a usable extend range of 80-90 mm, allowing on-machine end-position tuning without swapping parts. The retract stroke remains unaffected.
Because the piston area stays the same, output force equals a standard ACQ of this bore: 402.1 N push and 301.6 N pull at 0.5 MPa. It uses a PT1/8 port, a 16 mm rod, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 90 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 (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 ACQJ32X90-10 Is Used
Machining Fixture Stops
Dial in the exact 80 to 90 mm extend position on a CNC machining fixture to accommodate raw part tolerances without remachining hard stops.
Packaging Changeover
Rapidly adjust the rod extension during packaging line product changeovers, using the M12x1.25 external adjuster to set new reject or pusher endpoints.
Assembly Press Trials
Test various end positions on an automated assembly press, fine-tuning the extend stroke by up to 10 mm to find the optimal engagement depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10 the Right Cylinder?
Selecting this 32 mm bore provides 562.9 N push at 0.7 MPa, sitting between the 20 mm (219.9 N) and 40 mm (879.6 N) options. If your extend endpoint never varies, a fixed-stroke ACQ cylinder suffices. For this adjustable version, confirm the 90 mm full stroke, 10 mm window, female M8x1.25 rod end, and whether you need the -S magnet option for solid-state or reed 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 ACQJ32X90-10 FAQ
This 32 mm bore cylinder delivers 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 full stroke is 90 mm with a 10 mm adjustable window, giving a usable extend range of 80-90 mm.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke; the retract stroke is unaffected. The adjuster changes stroke length only, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions.
