Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75 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 ACQJ32X90-75
The AirTAC ACQJ32X90-75 is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. An M12x1.25 threaded screw and lock nut lets you shorten the forward stroke by up to 75 mm. This yields a usable extension span of 15 to 90 mm, while the retract distance remains fixed at 90 mm. You can dial in the exact end position directly on the equipment without swapping parts.
Because the piston diameter stays constant, output force matches a standard ACQ exactly. At 0.5 MPa it delivers 402.1 N of push and 301.6 N of pull. The body incorporates sensor grooves for reed or solid-state switches, though this specific unit ships without a magnet. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable pneumatic cushions.

| 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 ACQJ32X90-75 Is Used
Machining Fixture Stops
Dial in varying material thicknesses on a CNC fixture by turning the M12x1.25 adjuster to set the precise 15 to 90 mm clamp extension.
Packaging Changeover
Rapidly reconfigure product pusher end points during a packaging line format change without disassembling the cylinder or changing mounting hardware.
Assembly Press Trials
Establish the optimal pressing depth for new components on an automated assembly line by testing different extend lengths within the 75 mm window.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75 the Right Cylinder?
When sizing this unit, consider the adjacent bores: stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. If your application never requires altering the forward endpoint, a fixed-stroke ACQ cylinder is simpler and sufficient. For this adjustable variant, confirm your ordering code carefully: specify the 32 mm bore, 90 mm full stroke, 75 mm window, female M8x1.25 rod thread, and PT1/8 porting. Add the S suffix if you later require a magnet for position sensing.
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 ACQJ32X90-75 FAQ
This 32 mm bore cylinder generates 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 90 mm, but the external stop allows you to adjust the usable extend range from 15 mm up to 90 mm.
No, the output force remains identical to a standard ACQ because the piston area is unchanged; the external stop only limits how far the rod travels. The retract stroke is also unaffected. End-of-stroke deceleration is handled by fixed elastomer bumpers, so for high kinetic energy loads an external shock absorber may be needed.
