Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-100
The AirTAC ACQJ32X100-100 is a double-acting JIS compact cylinder with a 32mm bore and 100mm full stroke. An external M12x1.25 threaded stop and lock nut restricts the extend end position, providing a usable extend range of 0-100mm. You tune the forward stroke length directly on the machine without swapping parts. The retract stroke remains unaffected at the full 100mm.
Because the adjuster only limits travel, the piston area stays the same, meaning force is identical to a standard ACQ of this bore. The unit pushes 402.1N and pulls 301.6N at 0.5MPa. It features a 16mm rod, a PT1/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC lathe during part changeovers using the external stop, avoiding the need to manufacture custom spacer blocks.
Variable Carton Pushers
Adjust the ejection length on a packaging line to accommodate different box sizes on the fly, ensuring items align perfectly with downstream conveyors.
Assembly Press Trial
Set trial end positions for pressing bearings on an assembly line, safely testing the 0-100mm travel window before locking down the final production depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100 the Right Cylinder?
If your application needs less push, the 25mm bore version delivers 245.4N at 0.5MPa, while stepping up to the 40mm bore yields 628.3N. Choose this 32mm bore when your fixture requires roughly 402.1N of thrust. A fixed-stroke ACQ cylinder is sufficient if your extend position never changes. When ordering, confirm the 100mm full stroke, the 100mm adjustment window, the female M8x1.25 rod thread, and whether you need the S magnet option for position sensing.
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 ACQJ32X100-100 FAQ
This cylinder delivers a push force of 402.1N and a pull force of 301.6N at 0.5MPa, with a push of 562.9N at 0.7MPa. The maximum push is 82kgf at 1.0MPa. The full stroke is 100mm with a 100mm adjustment window, resulting in a usable extend range of 0-100mm.
No, the adjuster only shortens the extend stroke length, so force remains identical to a standard ACQ. The cylinder relies on fixed elastomer bumpers at both ends for deceleration rather than adjustable air cushions. For high-speed loads, an external shock absorber is recommended.
