Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50S 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 ACQJ32X150-50S
The ACQJ32X150-50S is a double-acting, single-rod JIS compact cylinder built for applications requiring a made-to-order 150 mm stroke. It features an external M12x1.25 threaded stop with a lock nut on the rod-end side. This mechanism limits the extend travel, allowing you to fine-tune the usable extend range from 100 mm up to the full 150 mm without swapping parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same bore. You get 402.1 N push and 301.6 N pull at 0.5 MPa. The body uses a compact C-clip design with a fixed NBR elastomer bumper at each end, and the integrated -S piston magnet works with both reed and solid-state electronic switches.

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 ACQJ32X150-50S Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC machining fixture to accommodate varying part lengths without machining new stop blocks.
Packaging Line Changeover
Adjust the extend reach on a packaging conveyor diverter during product format changeovers, saving downtime by turning the external stopper nut.
Assembly Press Trials
Set trial end positions on an automated assembly press, safely testing engagement depths before locking the rod-end adjuster for production runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50S the Right Cylinder?
This 32 mm bore delivers 402.1 N push at 0.5 MPa. If you need less force, a 25 mm bore provides 245.4 N push; for heavier loads, a 40 mm bore offers 628.3 N push. Since the 150 mm stroke exceeds the 100 mm standard maximum for this bore, this unit is supplied as a long-stroke variant. If your extend end position never changes, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the bore, full stroke, 50 mm adjustment window, -S magnet, and 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 ACQJ32X150-50S FAQ
It has a 32 mm bore and a 150 mm full stroke. The usable extend range is 100-150 mm via the 50 mm adjustment window. Force is identical to a standard ACQ: 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 port size is PT1/8.
An external M12x1.25 threaded stop and lock nut mechanically limits how far the rod extends, shortening the stroke without changing the piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration is handled by fixed elastomer bumpers at both ends, not an adjustable air cushion, so external shock absorbers are recommended for high-speed loads.
