Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 75mm 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 ACQJ32X75-30
The AirTAC ACQJ32X75-30 is a double-acting JIS compact cylinder featuring a 32mm bore and a 75mm full stroke. An external M12x1.25 threaded stop with a lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 45 to 75mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5 MPa. The body uses a compact C-clip design with fixed NBR elastomer bumpers at each end rather than adjustable air cushions. This specific configuration ships without a magnet, though the body retains magnetic-switch grooves for future sensing upgrades.

| Bore size | Ø32 mm |
| Full stroke | 75 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 ACQJ32X75-30 Is Used
CNC Machining Clamps
Dial in the exact clamping reach on machining centers during part changeovers by twisting the external stop, avoiding the need to fabricate custom spacer blocks.
Modular Assembly Stops
Adjust the physical end-stop position on the fly for assembly lines running mixed product variants, allowing quick format resets without swapping the actuator.
Packaging Pusher Setup
Establish trial end positions for carton pushing or folding mechanisms on packaging equipment, fine-tuning the 45 to 75mm stroke window to perfect the motion profile.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30 the Right Cylinder?
When sizing this 32mm bore actuator, compare your force needs against the 402.1N push at 0.5 MPa. Stepping down to a 25mm bore drops the push force to 245.4N, while moving up to a 40mm bore increases it to 628.3N. If your application never requires end-position variation, a fixed-stroke ACQ cylinder will suffice. To order this adjustable version correctly, confirm the 32mm bore, 75mm full stroke, 30mm adjustment window, female M8x1.25 rod-end thread, and PT1/8 porting.
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 ACQJ32X75-30 FAQ
This 32mm bore cylinder provides a push force of 402.1N and a pull force of 301.6N at 0.5 MPa, with a push of 562.9N at 0.7 MPa, and a maximum push of 82kgf at 1.0 MPa. The full stroke is 75mm with a 30mm adjustment window, yielding a usable extend range of 45 to 75mm.
No, the adjuster only limits the extend stroke length, so the force remains identical to a standard ACQ. The cylinder relies on fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. Note that this model ships without a magnet, though the body retains sensor grooves for adding reed or solid-state switches later.
