Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-50S
The AirTAC ACQJ32X80-50S is a double-acting, single-rod JIS compact cylinder featuring an external extend stop. An M12x1.25 threaded adjuster and lock nut let you fine-tune the forward end position on the machine, yielding a usable extend span of 30 to 80 mm from the 80 mm full stroke. The retract distance remains at the standard 80 mm. Because the piston area is unchanged, output force equals a standard ACQ, delivering 402.1 N push and 301.6 N pull at 0.5 MPa.
This unit includes a built-in piston magnet (-S) compatible with reed or solid-state sensors via its integrated grooves. It runs on PT1/8 ports, carries a 16 mm rod with an M8x1.25 female thread, and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.

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 ACQJ32X80-50S Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during setup. The external stop lets operators shift the extend end position by up to 50 mm without machining new spacers.
Assembly Line Product Changeover
Accommodate varying part heights on a conveyor assembly station. Adjust the forward stroke limit on the fly to handle different product families without swapping cylinders.
Carton Sealing Stops
Set precise flap-folding end positions for varying box sizes on a packaging line. The threaded stop provides repeatable positioning while the fixed bumper absorbs end impacts.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50S the Right Cylinder?
Choosing this 32 mm bore depends on your force and space needs. If 301.6 N pull at 0.5 MPa is insufficient, step up to the 40 mm bore (628.3 N push). If you need less force, the 25 mm bore offers 245.4 N push. A standard fixed-stroke ACQ32 is adequate if your extend position never varies. When ordering, confirm the 80 mm full stroke, 50 mm adjuster window, -S magnet, and female M8x1.25 rod end.

- ✓ 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 ACQJ32X80-50S FAQ
The usable extend range is 30 to 80 mm (80 mm full stroke minus a 50 mm window). The retract stroke is unaffected. Force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and 82 kgf max push at 1.0 MPa. The external adjuster uses an M12x1.25 thread.
No, the threaded stop only limits the extend length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses a fixed NBR elastomer bumper at each end, not an adjustable air cushion. Note that a plain ACQ does not hold its load on air loss; for fail-safe holding, use an external rod lock.
