Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50B 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 ACQJ32X80-50B
The AirTAC ACQJ32X80-50B 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 30 mm up to the full 80 mm stroke directly on the machine without swapping parts. The retract stroke remains completely unaffected. Equipped with a male M14x1.5 piston rod end, it couples directly to your load.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. The body features integrated magnetic-switch grooves, though this specific configuration ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 80 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X80-50B Is Used
Machining Fixture Stops
Dial in the exact clamping extend position on a CNC fixture during part changeovers without machining new spacers.
Carton Sealing Turrets
Adjust the sealing head stroke on the fly to accommodate varying box heights on a packaging line.
Laboratory Test Rigs
Set precise extend endpoints for repetitive material testing probes, tweaking the 30 to 80 mm travel as needed.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-50B the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N push at 0.5 MPa. If your application requires a fixed 80 mm extend stroke without on-machine tuning, a standard ACQ32X80 cylinder is sufficient. To order this adjustable variant correctly, confirm the 32 mm bore, 80 mm full stroke, 50 mm adjuster window, the male M14x1.5 rod thread, and the absence of a magnet.
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 ACQJ32X80-50B FAQ
It provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 30 to 80 mm (an 80 mm full stroke minus a 50 mm window), and the external adjuster thread is M12x1.25.
No, the adjuster only limits the extend stroke length, so the force remains identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper at each end, not an adjustable air cushion. Note that this model lacks a magnet for sensors and will not hold a load on air loss without an external rod lock.
