Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-100S 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 ACQJ32X90-100S
The AirTAC ACQJ32X90-100S 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 0 up to 90 mm directly on the machine without changing parts, while the retract stroke remains unaffected. Because the piston area stays the same, force is identical to a standard ACQ of this bore.
This 32 mm bore unit features a 16 mm piston rod, PT1/8 port, and a female M8x1.25 rod-end thread. It includes a built-in piston magnet (-S) compatible with reed or electronic solid-state switches, fixed elastomer bumpers at both ends, and an M12x1.25 adjuster thread. Operating pressure spans 0.15-1.0 MPa with speeds of 30-500 mm/s.

| 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 ACQJ32X90-100S Is Used
Machining Fixture Stops
Dial in the exact extend position from 0 to 90 mm on a CNC lathe loading fixture during part changeovers without machining new stop collars.
Carton Sealing Flap Folders
Accommodate varying package heights on a packaging line by tweaking the external extend stop nut to lower the flap folding arm precisely.
Assembly Press Travel Limits
Set trial end positions for a press operation in an automated assembly cell, using the lock nut to safely restrict the rod extension.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-100S the Right Cylinder?
If you need less push force, the 25 mm bore delivers 245.4 N @0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N @0.5 MPa. A fixed-stroke ACQ cylinder is sufficient if your extend position never requires adjustment. When ordering this adjustable model, confirm the 32 mm bore, 90 mm full stroke, 100 mm adjustment window, the -S magnet option, and your required rod 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 ACQJ32X90-100S FAQ
The usable extend range is 0-90 mm (full 90 mm stroke minus the 100 mm window). Force is unchanged from a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, changing only the stroke length, not the force. The cylinder uses fixed elastomer bumpers at each end, not adjustable air cushions. It will not hold a load on air loss, so add an external rod lock for fail-safe holding.
