Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 15mm 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 ACQJ32X15-20S
The ACQJ32X15-20S is a double-acting JIS compact cylinder with a 32mm bore and a 15mm full stroke. An external M12x1.25 threaded stop and lock nut lets you fine-tune the extend end position on the machine without swapping parts. With a 20mm adjustment window, the usable extend range runs from 0 to 15mm, while the retract stroke remains unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore. You get 402.1N push and 301.6N pull at 0.5MPa. The body uses fixed NBR elastomer bumpers at each end for deceleration, and the included -S magnet works with reed or solid-state electronic switches in the built-in grooves.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 15 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 ACQJ32X15-20S Is Used
Product Changeover Stops
Dial in the extend stroke from 0 to 15mm on packaging lines when switching between varying container sizes without machining new spacers.
Trial End Positions
Set precise clamping depth on test fixtures by adjusting the external stop screw, allowing rapid iteration during prototype machining.
Setup-Varying Fixtures
Accommodate varying workpiece thicknesses in automated assembly stations by tweaking the rod extension limit directly on the equipment.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20S the Right Cylinder?
If your setup only needs a fixed 15mm extension, a standard ACQ32X15S is sufficient. Choose this adjustable model when trial end positions or product-changeover stops require on-machine tuning. For higher force, the 40mm bore delivers 628.3N push at 0.5MPa; for less force, the 25mm bore provides 245.4N. Confirm ordering essentials: 32mm bore, 15mm full stroke, 20mm window, -S magnet, and the default M8x1.25 female rod-end thread. Porting is PT1/8.
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 ACQJ32X15-20S 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 15mm with a 20mm adjustment window, giving a usable extend range of 0-15mm. The retract stroke is unaffected.
An M12x1.25 threaded stop with a lock nut limits the extend length, changing only the stroke distance without altering the piston area or force. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. The cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
