Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm 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 ACQJ32X90-50
The AirTAC ACQJ32X90-50 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 40 mm up to the full 90 mm directly on the machine without changing parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The unit features a 16 mm piston rod, a PT1/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The body includes sensor grooves, though this specific configuration ships without a magnet.

| Bore size | Ø32 mm |
| Full stroke | 90 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 ACQJ32X90-50 Is Used
Machining Fixture Stops
Dial in the exact extend position from 40 to 90 mm on a CNC machining fixture to accommodate raw part tolerances without fabricating new spacer blocks.
Product Changeover Diverter
Adjust the end stop on a packaging line diverter to handle different carton lengths on the fly, ensuring positive positioning without reprogramming the PLC.
Prototype Press Testing
Find the optimal end-of-stroke contact point on a laboratory press by testing various extend positions, relying on the fixed NBR bumper to absorb impact energy.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50 the Right Cylinder?
When sizing this 32 mm bore actuator, consider the next size down and up for your force requirements. A 25 mm bore provides 245.4 N push at 0.5 MPa, while a 40 mm bore yields 628.3 N push at 0.5 MPa. If your application requires a fixed extend length that never changes, a standard ACQ cylinder without the external adjuster is sufficient. To order this adjustable model correctly, confirm the 32 mm bore, 90 mm full stroke, 50 mm adjustment window, female rod-end thread M8x1.25, and standard PT port. Note that this unit lacks the -S magnet option.
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 ACQJ32X90-50 FAQ
The usable extend range is 40 to 90 mm, adjustable via the M12x1.25 external stopper thread. The 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.
No, the external threaded stop only shortens the extend stroke length, not the piston area, so force remains unchanged. The retract stroke is unaffected. The cylinder uses fixed elastomer bumpers for deceleration rather than adjustable air cushions, and this model ships without a sensor magnet.
