Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X90-10
The AirTAC ACQJ40X90-10 is a double-acting JIS compact cylinder with an external threaded stop that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 80mm up to the full 90mm on the machine without swapping parts. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, force is identical to a standard ACQ of the same 40mm bore. The cylinder pushes 628.3N and pulls 527.8N at 0.5MPa, with a 16mm rod and PT1/8 port. It features NBR elastomer bumpers at both ends for fixed deceleration and integrated sensor grooves.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X90-10 Is Used
Machining Fixture Stops
Set precise clamping endpoints on machining centers, allowing operators to dial in material variance without reprogramming tool paths.
Conveyor Product Diversion
Adjust the extend stroke on packaging lines to handle different carton lengths during rapid product changeovers.
Assembly Press Positioning
Determine the ideal pressing depth for inserting bearings on a trial basis before locking the external M12x1.25 stop nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10 the Right Cylinder?
If you need less push force, the 32mm bore yields 402.1N at 0.5MPa, while the 50mm bore offers 981.8N for heavier loads. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering this model, confirm the 40mm bore, 90mm full stroke, 10mm window, female M8x1.25 rod thread, and that no magnet is included.
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 ACQJ40X90-10 FAQ
The usable extend range is 80-90mm (90mm full stroke minus up to 10mm). It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The retract stroke is unaffected.
No, the adjuster changes stroke length only, so force is identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for deceleration, not an adjustable air cushion. This model ships without a magnet.
