Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 25mm 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 ACQJ32X25-10SB
The AirTAC ACQJ32X25-10SB is a double-acting JIS compact cylinder featuring a 32mm bore and a 25mm full stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 15mm up to 25mm directly on your equipment without changing parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa. This unit includes a built-in piston magnet for electronic or reed switches and a male M14x1.5 rod-end thread for direct load coupling. It uses a PT1/8 port and relies on a fixed elastomer bumper for end-of-stroke deceleration.

| 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10SB Is Used
Machining Fixture Stops
Dial in the exact extend position for varying raw material thicknesses on a milling fixture without fabricating custom spacer blocks.
Assembly Line Changeover
Quickly alter the extend endpoint during product family changeovers on automated assembly equipment to handle different component widths.
Carton Sealing Trials
Test and set precise folding positions for various carton sizes on a packaging line, using the external stop to find the optimal travel.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10SB the Right Cylinder?
If you need less push force, the 25mm bore ACQJ series provides 245.4N push at 0.5MPa, or step up to the 40mm bore for 628.3N. If you do not require on-machine end-position tuning, a standard fixed-stroke ACQ32 cylinder is sufficient. To order this adjustable variant correctly, confirm the 32mm bore, 25mm full stroke, 10mm adjustment window, the S magnet option, and the B male 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 ACQJ32X25-10SB FAQ
It delivers 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 10mm adjustment window provides a usable extend range of 15-25mm.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion.
