Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10S 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 ACQJ32X90-10S
The AirTAC ACQJ32X90-10S 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 stroke from 80mm up to the full 90mm directly on your equipment, while the retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This 32mm bore unit delivers 402.1N of push force and 301.6N of pull force at 0.5 MPa. It includes a built-in magnet for position sensing, compatible with reed or electronic solid-state switches. The body utilizes fixed elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions.

| 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 |

| 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 ACQJ32X90-10S Is Used
Machining Fixture Stops
Dial in exact clamping extension on CNC fixtures to accommodate varying raw material thicknesses without machining new stop collars.
Product Changeover Diverter
Adjust the extend position of a sorting gate on a packaging line to handle different carton lengths during rapid product changeovers.
Assembly Press Positioning
Set precise end-of-stroke limits on an assembly press for trial end positions during new product line setup and cycle debugging.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10S the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: a 25mm version provides 245.4N push at 0.5 MPa, whereas a 40mm unit yields 628.3N. If your application never requires stroke adjustments, a fixed-stroke ACQ cylinder will suffice. To order this adjustable model correctly, confirm the 32mm bore, 90mm full stroke, 10mm adjustment window, the S magnet option, and your preferred rod-end 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 ACQJ32X90-10S FAQ
It has a 32mm bore and a 90mm full stroke with a 10mm adjustment window, giving a usable extend range of 80-90mm. The force equals a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the stroke without changing the piston area, so force is unchanged. The cylinder uses fixed elastomer bumpers for deceleration and will not hold a load on air loss; for fail-safe holding, use an external rod lock.
