Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20 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 ACQJ32X90-20
The AirTAC ACQJ32X90-20 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 70 mm up to the full 90 mm directly on your machine, shortening the stroke by up to 20 mm without swapping components. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force equals a standard ACQ of the same 32 mm bore, delivering 402.1 N push at 0.5 MPa. The body utilizes a fixed elastomer bumper at each end for deceleration and includes magnetic-switch grooves. This specific configuration ships without a piston magnet, features a female M8x1.25 rod-end thread, and uses a PT1/8 port.

| 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 ACQJ32X90-20 Is Used
Fixture Position Tuning
Dial in the exact clamping extend position from 70 to 90 mm during initial fixture setup without machining custom spacers.
Product Changeover Stops
Adjust the extend end stop on a packaging line to accommodate varying carton depths quickly and keep downtime minimal.
Prototype End Positions
Test different extend endpoints on a laboratory test rig to find the optimal travel before finalizing the mechanical layout.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20 the Right Cylinder?
If you require less push force, the 25 mm bore yields 245.4 N at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. A fixed-stroke ACQ32X90 is sufficient if your end position never requires shifting. When ordering, verify the 32 mm bore, 90 mm full stroke, 20 mm adjuster window, female M8x1.25 rod thread, and confirm whether you need the -S magnet option for reed or solid-state sensors.
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 ACQJ32X90-20 FAQ
The usable extend range is 70-90 mm (90 mm full stroke minus the 20 mm window). It 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 external M12x1.25 threaded stop with lock nut limits only the extend stroke length; it does not alter the piston area, so force remains identical to a standard ACQ. Deceleration relies on a fixed elastomer bumper, and since this model lacks a -S magnet, it will drift if air pressure is lost.
