Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 35mm 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 ACQJ32X35-30B
The AirTAC ACQJ32X35-30B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND end position. You can fine-tune the usable extend range from 5 mm up to the full 35 mm directly on your machine without swapping parts. The RETRACT stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the force output is identical to a standard ACQ of the same bore. This 32 mm bore unit delivers 402.1 N push force at 0.5 MPa. It includes a male M14x1.5 rod-end thread for direct load coupling, a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and a PT1/8 port. The body retains magnetic-switch grooves, though this specific configuration ships without a magnet.

| 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 ACQJ32X35-30B Is Used
Machining Fixture Stops
Dial in the exact extend position from 5 to 35 mm on a CNC machining fixture to accommodate raw part tolerances without fabricating new spacer blocks.
Packaging Changeover
Adjust the extend stroke on a carton sealing machine to hit different box heights rapidly, utilizing the male M14x1.5 thread to mount the sealing head directly.
Assembly Press Tria
Test different end positions for pressing bearings on an assembly line, relying on the fixed elastomer bumper to handle the 402.1 N impact at 0.5 MPa.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30B the Right Cylinder?
When sizing this unit, consider the 32 mm bore alongside its neighbors: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore provides 628.3 N. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient. For variable stops, confirm your ordering essentials: 32 mm bore, 35 mm full stroke, 30 mm adjustable window, male rod thread (-B), and no magnet. The external adjuster uses an M12x1.25 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 ACQJ32X35-30B FAQ
This 32 mm bore cylinder delivers 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. The full stroke is 35 mm with a 30 mm adjustable window, allowing the usable extend range to be set anywhere from 5 mm to 35 mm.
No, the external M12x1.25 threaded stop only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration; it is not an adjustable air cushion, so for high-energy impacts you should slow the approach or add an external shock absorber.
