Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75S 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 ACQJ32X90-75S
The AirTAC ACQJ32X90-75S is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend end position. With a full stroke of 90 mm and a 75 mm adjustment window, you can fine-tune the usable extend range from 15 mm up to 90 mm directly on the machine. The retract stroke remains completely unaffected by this mechanism. A built-in piston magnet (-S) is included, compatible with both reed and electronic solid-state switches.
Because the adjuster only alters travel length and not piston area, the output force remains identical to a standard ACQ of the same bore. At 0.5 MPa, it delivers 402.1 N of push force and 301.6 N of pull force. The unit uses a PT1/8 port, a 16 mm piston rod, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ32X90-75S Is Used
Machining Fixture Stops
Dial in the exact 15-90 mm extend position for part clamps during CNC changeovers without machining new stop blocks.
Packaging Line Changeover
Adjust the extend stroke on-site to accommodate different carton sizes or sealing heads rapidly.
Assembly Press Positioning
Set precise end positions for light-duty pressing or locating pins during new product prototype runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75S the Right Cylinder?
For lower force needs, the 25 mm bore provides 245.4 N push @0.5 MPa, while the larger 40 mm bore yields 628.3 N push @0.5 MPa for heavier demands. Choose this 32 mm model when your application requires precise 15-90 mm extend positioning and roughly 400 N of force. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 32 mm bore, 90 mm full stroke, 75 mm window, -S magnet, and female M8x1.25 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 ACQJ32X90-75S FAQ
It delivers 402.1 N push and 301.6 N pull @0.5 MPa, 562.9 N push @0.7 MPa, and a maximum push of 82 kgf @1.0 MPa. The usable extend range is 15-90 mm (90 mm full stroke minus up to 75 mm window).
An external M12x1.25 threaded stop with a lock nut limits the extend travel without changing the piston area, so force stays identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers, not adjustable air cushions.
