Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-10S
The AirTAC ACQJ32X45-10S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 35 mm up to the full 45 mm directly on your equipment without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, the output force equals a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. This 32 mm bore unit features a 16 mm rod, PT1/8 port, fixed NBR elastomer bumpers at both ends, and a built-in piston magnet for position sensing.

| 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 ACQJ32X45-10S Is Used
Assembly Press Tuning
Dial in the exact 35-45 mm extend position during a new product run on an assembly press without machining new spacers.
Variable Fixture Stops
Adapt end-stop locations quickly on multi-model machining fixtures when raw part blanks vary slightly in length.
Carton Forming Adjustments
Set precise extend distances for different carton sizes on packaging lines, relying on the fixed bumper for end deceleration.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10S the Right Cylinder?
If you need slightly less push force, the 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. A fixed-stroke ACQ is adequate if your end position never requires tweaking. For this adjustable model, confirm the 32 mm bore, 45 mm full stroke, 10 mm window, S magnet, and female M8x1.25 rod end thread.
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 ACQJ32X45-10S FAQ
It 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 45 mm with a 10 mm window, allowing a usable extend range of 35-45 mm.
The M12x1.25 external stop only shortens the extend stroke length; it does not alter the piston area, so force remains identical to a standard ACQ. The included -S magnet works with reed or electronic solid-state switches, and fixed elastomer bumpers decelerate the load at stroke ends.
