Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-20B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 60mm 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 ACQJ32X60-20B
The AirTAC ACQJ32X60-20B is a double-acting JIS compact cylinder with an external extend-stop mechanism. A threaded adjuster screw with a lock nut on the rod-end side limits how far the piston travels outward. With a 60 mm full stroke and a 20 mm window, you get a usable extend range of 40-60 mm. The retract stroke remains completely unaffected by this adjustment.
Because the adjuster only restricts travel length and leaves piston area untouched, output force stays identical to a standard ACQ of this bore. You get 402.1 N push and 301.6 N pull at 0.5 MPa. The body features a compact riveted design with fixed elastomer bumpers at both ends and pre-machined grooves for mounting sensors. This variant includes a male-thread piston rod end (M14x1.5) for direct load coupling.

| 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 |

| 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 ACQJ32X60-20B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during part changeovers. The external stop lets operators shift the extend position between 40 and 60 mm without swapping cylinders.
Package Sorting Diverters
Adjust the pusher extension distance on the fly to handle varying carton widths on a packaging line. The male M14x1.5 rod threads directly into the diverter arm.
Assembly Line Stops
Set precise end-of-stroke positions for product stops on an assembly conveyor. The fixed NBR bumpers absorb the impact energy at the end of travel.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-20B the Right Cylinder?
This 32 mm bore delivers 402.1 N push at 0.5 MPa. If you need less force, the 25 mm bore provides 245.4 N push; for heavier jobs, the 40 mm bore offers 628.3 N push. Sizing this model requires specifying the 32 mm bore, 60 mm full stroke, and the 20 mm adjust window. Since this unit ships without a magnet, select it if you do not need position sensing, but remember to add the -S suffix if your control system requires reed or solid-state switch feedback.
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 ACQJ32X60-20B FAQ
At 0.5 MPa it provides 402.1 N push and 301.6 N pull force, and 562.9 N push at 0.7 MPa. The maximum push force is 82 kgf at 1.0 MPa. The full stroke is 60 mm with a 20 mm adjustment window, giving a usable extend range of 40-60 mm. The retract stroke remains fixed.
An external M12x1.25 threaded stop screw with a lock nut physically limits the outward travel, allowing on-machine position tuning without replacing parts. This mechanism changes stroke length only, so output force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers at both ends for deceleration rather than adjustable air cushions.
