Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 300mm 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 ACQJ32X300-100B
The ACQJ32X300-100B is a double-acting, single-rod JIS compact cylinder built for applications requiring a long 300 mm stroke with on-machine extend tuning. An external M12x1.25 threaded stop and lock nut lets you shorten the forward stroke by up to 100 mm, yielding a usable extend range of 200 to 300 mm. The retract distance remains fixed at 300 mm. Because the piston area is unchanged, output force matches a standard ACQ exactly: 402.1 N push and 301.6 N pull at 0.5 MPa.
This made-to-order variant exceeds the 100 mm standard stroke maximum for a 32 mm bore, extending into the 300 mm long-stroke category. It features a male M14x1.5 rod-end thread for direct load coupling, a PT1/8 port, and fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The body includes magnetic-switch grooves, though this specific SKU ships without a magnet.

| 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 ACQJ32X300-100B Is Used
Fixture Changeover
Dial in the exact extend stop between 200 and 300 mm on machining centers when swapping out part fixtures, avoiding the need to physically swap cylinder hardware.
Packaging Diverter Setup
Fine-tune the pusher rod extension on packaging lines to accommodate varying carton widths on the fly without changing out the entire actuator assembly.
Assembly Press Trials
Safely test different end positions for pressing or seating components during new product line commissioning by simply turning the external stop screw.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100B the Right Cylinder?
Choose this 32 mm bore actuator when you need 402.1 N push at 0.5 MPa alongside variable end positioning. If your project requires less force, the 25 mm bore delivers 245.4 N push; for heavier loads, stepping up to the 40 mm bore provides 628.3 N push. A fixed-stroke ACQ is sufficient if the extend endpoint never needs field adjustment. Confirm your ordering essentials: 32 mm bore, 300 mm full stroke, 100 mm adjuster window, male rod thread (-B), and no magnet. Note that standard bore 32 strokes max out at 100 mm, so this 300 mm version is a long-stroke configuration.
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 ACQJ32X300-100B FAQ
This cylinder has a 32 mm bore and a 300 mm full stroke. The adjustable extend window is 100 mm, allowing a usable extend range of 200 to 300 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 extend distance without altering the piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
