Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X15-10
The AirTAC ACQJ40X15-10 is a double-acting JIS compact cylinder with a 15mm full stroke and a 10mm adjustable extend window. An external M12x1.25 threaded stop and lock nut lets you set the extend end position anywhere from 5 to 15mm without swapping parts. The retract stroke remains completely unaffected.
Because the adjuster only limits travel, output force matches a standard ACQ of the same bore: 628.3N push and 527.8N pull at 0.5MPa. The 40mm bore uses a PT1/8 port and a 16mm rod. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X15-10 Is Used
Machining Fixture Stops
Dial in the exact 5-15mm extend position for varying raw material blanks on a CNC lathe without machining new spacer blocks.
Product Changeover Pins
Rapidly reposition locating pins on a packaging line by turning the external stop screw when switching carton sizes.
Prototype End Positions
Safely trial different extend endpoints during assembly machine development before locking the lock nut at the optimal distance.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10 the Right Cylinder?
If 879.6N push at 0.7MPa is excessive, consider a 32mm bore (562.9N push at 0.7MPa). If your application needs more power, step up to a 50mm bore (1374.4N push at 0.7MPa). A fixed-stroke ACQ is adequate if your end position never varies. This SKU ships without a magnet; order the -S option if you require reed or solid-state switch sensing. Confirm the female M8x1.25 rod-end thread suits your mounting.
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 ACQJ40X15-10 FAQ
It has a 40mm bore, 15mm full stroke, and a 10mm adjustment window, giving a usable extend range of 5-15mm. The force is identical to a standard ACQ: 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend travel; retract is unaffected. The piston area is unchanged, so force remains identical. Fixed NBR bumpers handle end deceleration. Note that this cylinder will not hold a load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
