Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20SB 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 ACQJ32X100-20SB
The AirTAC ACQJ32X100-20SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the extend side. This mechanism lets you fine-tune the extend end position directly on your machine, providing a usable extend range of 80-100mm from the 100mm full stroke, while the retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of the same bore. At 0.5MPa it delivers 402.1N of push and 301.6N of pull. The unit includes a -S piston magnet compatible with reed or solid-state switches, a -B male M14x1.5 rod end for direct load coupling, PT1/8 ports, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 100 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X100-20SB Is Used
Machining Fixture Clamping
Dial in the exact 80-100mm clamping reach on a CNC fixture during setup, accommodating varying part tolerances without swapping cylinders.
Assembly Line Product Changeover
Quickly reposition the extend stop for a new product run on a packaging conveyor, adjusting the push distance by up to 20mm on-site.
Test Rig End-Position Trials
Experiment with different extend endpoints on a laboratory test rig, using the M12x1.25 adjuster to find the optimal contact position.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20SB the Right Cylinder?
Choosing this 32mm bore involves weighing 402.1N push @0.5MPa against adjacent sizes: stepping down to 25mm yields 245.4N, while moving up to 40mm provides 628.3N. If your extend position never varies, a fixed-stroke ACQ suffices; otherwise, this model's 20mm window offers excellent on-machine tuning. When ordering, confirm the 32mm bore, 100mm full stroke, 20mm window, -S magnet, and -B male M14x1.5 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 ACQJ32X100-20SB FAQ
It provides 402.1N push and 301.6N pull @0.5MPa, 562.9N push @0.7MPa, and a maximum push of 82kgf @1.0MPa. The full stroke is 100mm with a 20mm adjustable window, giving a usable extend range of 80-100mm.
No, the adjuster only changes the extend stroke length; force remains identical to a standard ACQ because piston area is unchanged. The cylinder uses fixed elastomer bumpers, not air cushions, and a plain ACQ will drift on air loss, so use an external rod lock for fail-safe holding.
