Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75 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 ACQJ32X150-75
The ACQJ32X150-75 is a double-acting JIS compact cylinder featuring a 150 mm total stroke and a 75 mm adjustable extend window. An external M12x1.25 threaded stop with a lock nut lets you set the forward end position anywhere between 75 and 150 mm directly on your machinery. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force equals a standard ACQ of the same bore.
This long-stroke made-to-order variant exceeds the standard 100 mm maximum for a 32 mm bore, reaching up to the 300 mm extended range. It delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. The unit incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. A 16 mm rod with a female M8x1.25 end thread and a PT1/8 port ensure straightforward integration.

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 ACQJ32X150-75 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on CNC machining centers during setup. The external stop allows operators to shift the extend endpoint between 75 and 150 mm without machining new spacer blocks.
Packaging Product Changeover
Adapt pusher lengths on packaging lines for different carton sizes. The lock nut enables rapid manual adjustment of the forward position to handle varied format widths on the fly.
Assembly Press Trials
Establish precise trial end positions for pressing sub-components. The threaded stop lets engineers fine-tune the 32 mm bore extension depth safely before locking down the final production cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75 the Right Cylinder?
When sizing this actuator, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.4 N, while moving up to a 40 mm bore raises it to 628.3 N. If your machinery never requires altering the extend endpoint, a fixed-stroke ACQ cylinder provides the same holding power without the external hardware. To order correctly, confirm the 32 mm bore, 150 mm total stroke, 75 mm window, female rod thread, and whether you need the S magnet option for position sensing.
Quick checklist

- ✓ 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 ACQJ32X150-75 FAQ
This 32 mm bore cylinder 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 spans from 75 mm up to the full 150 mm, adjustable via a 75 mm window.
The M12x1.25 threaded stop mechanically limits the forward stroke length without altering the piston area, so output force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers rather than adjustable air cushions. It will not hold a load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
