Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75B 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 ACQJ32X80-75B
The AirTAC ACQJ32X80-75B is a double-acting, single-rod 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 range from 5 mm up to the full 80 mm on the machine without changing parts, while the retract stroke remains unaffected. It includes a male-thread piston rod end (M14x1.5) for direct load coupling.
Because the adjuster only changes stroke length and not piston area, the output force is identical to a standard ACQ of the same bore. The cylinder uses a fixed elastomer bumper at each end for end-of-travel deceleration and operates at speeds from 30-500 mm/s.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75B |
|---|---|
| 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 ACQJ32X80-75B Is Used
Fixture Setup Tuning
Dial in the exact extend stop during initial fixture setup on a machining line, shortening the stroke from 80 mm down to 5 mm as needed for precise tool clearance.
Product Changeover
Adjust the external rod-end stop to accommodate different part lengths on a packaging conveyor without swapping out the entire cylinder body.
Trial End Positions
Test and verify different extend end positions on an assembly press prototype by sliding the lock nut along the M12x1.25 adjuster thread before locking it down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75B the Right Cylinder?
If you need less push force, the adjacent ACQJ25 bore provides 245.4 N @0.5 MPa, or for more power, the ACQJ40 bore yields 628.3 N @0.5 MPa. A fixed-stroke ACQ32X80 is sufficient if your end position never requires variation. To order this unit, confirm the 32 mm bore, 80 mm full stroke, 75 mm adjustable window, male rod thread, and note that this configuration ships without 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 ACQJ32X80-75B FAQ
It delivers 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 full stroke is 80 mm with a 75 mm adjustable window, giving a usable extend range of 5-80 mm.
The external M12x1.25 threaded stop with a lock nut limits the extend stroke length only; it does not alter the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper at stroke end, not an adjustable air cushion.
