Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 40mm 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 ACQJ32X40-30S
The AirTAC ACQJ32X40-30S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You get a usable extend range of 10 to 40 mm, while the retract stroke remains unaffected. Because the piston area stays the same, force is identical to a standard ACQ of this bore.
This 32 mm bore unit delivers 402.1 N push and 301.6 N pull at 0.5 MPa. It features a fixed NBR elastomer bumper at each end, PT1/8 ports, and a built-in magnet (-S) for position sensing. The external adjuster uses an M12x1.25 thread to set your end position precisely on the machine.

| 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 ACQJ32X40-30S Is Used
Machining Clamp Tuning
Dial in the exact clamping extension on a CNC fixture during first-article inspection without swapping cylinders.
Product Changeover Stops
Adjust the extend endpoint on packaging lines to accommodate different carton sizes on the fly.
Prototype End Positions
Find the optimal push distance on a test rig by turning the external stop screw, then locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30S the Right Cylinder?
If you need less push force, the 25 mm bore yields 245.4 N at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. Choose this model when your end position requires frequent trial adjustments or product changeovers; a fixed-stroke ACQ is simpler if the extend length never varies. Confirm your ordering essentials: 32 mm bore, 40 mm full stroke, 30 mm window, -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 ACQJ32X40-30S 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 40 mm with a 30 mm adjustable window, giving a usable extend range of 10 to 40 mm. It uses PT1/8 ports, a female M8x1.25 rod-end thread, and an M12x1.25 external adjuster thread.
No, the external stop only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for end-of-stroke deceleration, not an adjustable air cushion. Note that a plain compact cylinder will not hold a load if air pressure is lost; for fail-safe holding, add an external rod lock.
