Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40SB 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 ACQJ32X80-40SB
The AirTAC ACQJ32X80-40SB is a double-acting JIS compact cylinder featuring a 32mm bore and an 80mm full stroke. Equipped with a male M14x1.5 piston rod end, it incorporates an external M12x1.25 threaded stop and lock nut to regulate the extend end position. You can fine-tune the usable extend range from 40mm up to 80mm directly on your machinery, while the retract stroke remains completely unaffected.
Because the internal piston area does not change, output force matches a standard ACQ unit exactly, yielding 402.1N push and 301.6N pull at 0.5MPa. The body includes fixed NBR elastomer bumpers at both ends to absorb impact energy rather than relying on adjustable air cushions. A built-in magnet, activated by the -S option, enables tracking via reed or solid-state electronic switches fitted into the standard grooves.

| 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 ACQJ32X80-40SB Is Used
Machining Fixture Positioning
Dial in the exact clamping reach on a CNC fixture by turning the external stop, allowing rapid accommodation of different raw material widths without swapping cylinders.
Assembly Line Changeover
Modify the extend endpoint during product family transitions on a packaging conveyor, hitting distinct push distances for varying carton sizes using the same actuator.
Prototype End-Stop Testing
Sweep through multiple extend lengths on a test rig to determine the optimal pressing depth for a new component insertion process before finalizing the design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40SB the Right Cylinder?
When sizing this unit, stepping down to a 25mm bore provides 157.1N push, whereas stepping up to a 40mm bore yields 628.3N push at 0.5MPa. If your application requires a fixed 80mm extend position without any on-machine tuning, a standard ACQ32X80 will suffice and saves adjustment time. To order this adjustable variant correctly, confirm the 32mm bore, 80mm full stroke, 40mm adjustment window, the -S magnet requirement, and the -B male M14x1.5 rod thread.
Quick checklist

- ✓ 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 ACQJ32X80-40SB FAQ
At 0.5MPa it generates 402.1N push and 301.6N pull force, reaching 562.9N push at 0.7MPa, with a maximum push capacity of 82kgf at 1.0MPa. The 40mm adjustment window allows the usable extend range to be set anywhere from 40mm to 80mm, while the retract stroke remains fixed at its standard length.
An external M12x1.25 threaded screw with a lock nut mechanically limits how far the rod extends, shortening the stroke without altering the piston area, so output force stays identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers rather than adjustable air cushions. Note that a plain cylinder will not hold a load if air pressure drops; for fail-safe load holding, utilize an external rod lock or pilot-operated check valve.
