Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-10B 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 ACQJ32X100-10B
The AirTAC ACQJ32X100-10B is a double-acting JIS compact cylinder with a 32mm bore and a 100mm full stroke. It features an external M12x1.25 threaded stop with a lock nut that limits the extend end position. You get a usable extend range of 90-100mm, allowing precise on-machine tuning without swapping parts. The retract stroke remains completely unaffected.
Because the adjuster only shortens travel, the piston area stays the same, meaning force is identical to a standard ACQ of this bore. You get 402.1N push and 301.6N pull at 0.5MPa. This variant includes a male M14x1.5 rod-end thread (-B) for direct load coupling. It uses a PT1/8 port, fixed NBR elastomer bumpers at both ends, and operates at speeds from 30-500mm/s. Note that this specific unit ships without a sensor magnet.

| 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 |

| 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 ACQJ32X100-10B Is Used
Machining Fixture Stops
Dial in the extend position exactly to 90-100mm on a CNC machining fixture to accommodate raw part tolerances without fabricating new hard stops.
Packaging Changeover
Quickly alter the extend endpoint during packaging line format changeovers to push different carton sizes without adjusting software timers.
Assembly Press Trials
Set trial end positions on an automated assembly press to test insertion depths safely before locking down the final mechanical stop distance.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-10B the Right Cylinder?
Selecting this 32mm bore provides 402.1N push at 0.5MPa. If you need less force, stepping down to a 25mm bore yields 245.4N push, while moving up to a 40mm bore provides 628.3N. Choose this adjustable version if your fixture setup requires trial end positions or product-changeover flexibility. If your application always uses the exact same 100mm extend distance, a fixed-stroke ACQ cylinder will suffice. When ordering, confirm the 32mm bore, 100mm full stroke, 10mm window, the male rod thread (-B), and whether you need the magnet option (-S) for switch detection.
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 ACQJ32X100-10B FAQ
This 32mm bore cylinder 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 full stroke is 100mm, but the external stop provides a 10mm adjustment window, giving a usable extend range of 90-100mm.
An external M12x1.25 threaded screw with a lock nut physically limits how far the rod extends, shortening travel without changing the piston area or force output. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. As a standard double-acting cylinder, it will not hold a load if air pressure is lost; use an external rod lock for fail-safe holding.
