Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20 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 ACQJ32X15-20
The AirTAC ACQJ32X15-20 is a double-acting JIS compact cylinder featuring an external M12x1.25 threaded stop with a lock nut. This mechanism limits the extend stroke, allowing you to dial in the end position from 0 to 15 mm on the machine without swapping parts. The retract movement remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. You get 402.1 N push and 301.6 N pull at 0.5 MPa. The body uses a fixed NBR elastomer bumper for end-of-stroke deceleration and includes sensor grooves, though this specific SKU ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20 |
|---|---|
| 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 ACQJ32X15-20 Is Used
Machine Tending Setup
Dial in the exact extend endpoint from 0 to 15 mm during initial commissioning to accommodate varying gripper jaw lengths without machining new spacers.
Product Changeover Stops
Quickly adjust the extend position on a packaging line when switching between different carton widths, using the external lock nut to secure the new stroke limit.
Assembly Press Positioning
Fine-tune the pressing depth of a 32 mm bore actuator on an assembly line to test trial end positions safely before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20 the Right Cylinder?
For sizing context, stepping down to a 25 mm bore yields 245.4 N push @0.5 MPa, while a 40 mm bore provides 628.3 N. If your setup never requires altering the extend endpoint, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable unit, confirm the 32 mm bore, 15 mm full stroke, 20 mm window, female M8x1.25 rod end, and PT1/8 porting.
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 ACQJ32X15-20 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 15 mm with a 20 mm adjustment window, allowing a usable extend range of 0-15 mm.
The external M12x1.25 threaded stop and lock nut mechanically limit the extend distance, changing only the stroke length and not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for deceleration rather than adjustable air cushions, and while the body has sensor grooves, this specific model ships without a magnet.
