Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm 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 ACQJ32X150-75S
The AirTAC ACQJ32X150-75S is a double-acting, single-rod JIS compact cylinder engineered for adjustable extend stroke. Because the full 150mm stroke exceeds the standard 100mm catalog limit for a 32mm bore, this unit is produced as a long-stroke, made-to-order variant. An external threaded stop with a lock nut limits how far the rod extends, yielding a usable forward range of 75 to 150mm. The retract movement remains fixed and unaffected by this adjustment.
Since the piston area is unchanged, output force is identical to a standard ACQ of this bore: 402.1N push and 301.6N pull at 0.5MPa. The body incorporates fixed elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. Equipped with a piston magnet (-S), it supports both reed and electronic solid-state switches via integrated grooves.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 150 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 ACQJ32X150-75S Is Used
Machining Fixture Stops
Dial in exact clamping reach on multi-part machining fixtures without machining new spacers or swapping cylinder bodies.
Product Changeover
Rapidly reposition the extend end stop for packaging line format changes, accommodating varying carton heights on the fly.
Prototype End Positions
Safely test trial forward end positions on new automation equipment before locking the lock nut for final production runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75S the Right Cylinder?
When sizing this unit, consider the 32mm bore neighbors: stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while stepping up to a 40mm bore provides 628.3N. If your application requires a fixed 150mm extend without on-machine tuning, a standard ACQ32x150 cylinder suffices. To order, confirm the 32mm bore, 150mm full stroke, 75mm adjuster window, the -S magnet, and the default female M8x1.25 rod-end thread.
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 ACQJ32X150-75S FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The full stroke is 150mm, and with the 75mm window, the usable extend range is 75-150mm.
No, the external M12x1.25 adjuster only changes the extend length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions.
