Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30S 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 ACQJ32X45-30S
The AirTAC ACQJ32X45-30S is a double-acting JIS compact cylinder with an external extend stop. A threaded adjuster with a lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 15-45mm from the 45mm full stroke. The retract stroke remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore: 402.1N push and 301.6N pull at 0.5MPa. The body uses fixed elastomer bumpers instead of adjustable air cushions, and the included -S magnet works with reed or electronic solid-state switches in the built-in sensor grooves.

| 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 |

| 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.

Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30S the Right Cylinder?
For lower force needs, the 25mm bore delivers 245.4N push at 0.5MPa, while stepping up to a 40mm bore provides 628.3N. If your equipment never requires position tuning, a fixed-stroke ACQ cylinder is sufficient. When ordering this unit, verify the 32mm bore, 45mm full stroke, 30mm adjustment window, -S magnet, and the default female M8x1.25 rod 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 ACQJ32X45-30S FAQ
It provides 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 45mm with a 30mm window, allowing an adjustable extend range of 15-45mm.
The M12x1.25 threaded stop with lock nut limits the extend length without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration, and the -S magnet supports reed or solid-state switches.
