Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-40S 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 ACQJ32X90-40S
The AirTAC ACQJ32X90-40S is a double-acting JIS compact cylinder with a 32mm bore and 90mm full stroke. An external M12x1.25 threaded stop and lock nut restricts the extend end position, yielding a usable extend range of 50-90mm. The retract distance remains fixed at 90mm. A built-in piston magnet (-S) pairs with reed or solid-state switches.
Because the adjuster only limits travel, the piston area stays intact, meaning force is identical to a standard ACQ of this bore. You get 402.1N push and 301.6N pull at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| 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 ACQJ32X90-40S Is Used
Machine Tending Setup
Dial in the exact 50-90mm extend position for varying part lengths on a lathe loader without machining new spacers.
Product Changeover Stops
Shift the external stop to accommodate different carton widths on a packaging line during rapid format transitions.
Prototype End Positions
Safely trial different extend endpoints on a test rig to find the optimal 32mm bore actuation distance before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-40S the Right Cylinder?
If you need less push force, the 25mm bore yields 245.4N at 0.5MPa, while stepping up to the 40mm bore provides 628.3N. Choose this 32mm option when your setup requires 402.1N of thrust and on-the-fly end-position tuning. If your extend position never varies, a fixed-stroke ACQ suffices. Confirm ordering essentials: 32mm bore, 90mm full stroke, 40mm window, S magnet, and female M8x1.25 rod thread with PT1/8 port.
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 ACQJ32X90-40S FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The full stroke is 90mm with a 40mm window, giving a usable extend range of 50-90mm.
No, the adjuster only limits the extend travel, so force remains identical to a standard ACQ and the retract stroke is unaffected. Deceleration relies on a fixed elastomer bumper, not an adjustable air cushion.
