Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 20mm 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 ACQJ32X20-10SB
The AirTAC ACQJ32X20-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get an adjustable extend range of 10 to 20 mm, letting you fine-tune the forward stroke directly on your equipment without swapping parts. The retract stroke remains unaffected. Equipped with a male M14x1.5 rod end, it couples directly to your load.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore: 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port and a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The built-in piston magnet works with reed or solid-state switches.

| 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 ACQJ32X20-10SB Is Used
Machining Fixture Stops
Dial in the exact 10 to 20 mm extend position on a CNC machining fixture to accommodate raw part tolerances without machining new spacer blocks.
Product Changeover Pins
Rapidly adjust the extend stroke on a packaging line during format changeovers, using the external stop to set new product push-off distances.
Prototype End Positions
Test various extension endpoints on laboratory automation equipment, fine-tuning the forward travel in 1 mm increments to perfect a assembly motion.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10SB the Right Cylinder?
If your application requires less push force, the next smaller bore (25 mm) provides 245.4 N push at 0.5 MPa, whereas the next larger size (40 mm) yields 628.3 N. Choose this 32 mm model when you need around 402.1 N of push force and on-machine extend tuning. If the forward position never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 32 mm bore, 20 mm full stroke, 10 mm window, the -S magnet, 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 ACQJ32X20-10SB FAQ
The usable extend range is 10 to 20 mm. Force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the forward stroke; it changes stroke length only, not force. Fixed elastomer bumpers absorb end impacts. Note that this cylinder will not hold its load on air loss, so an external rod lock is needed for fail-safe holding.
