Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X60-20SB
The AirTAC ACQJ40X60-20SB is a double-acting JIS compact cylinder with a 60mm full stroke and a 20mm adjustable extend window. An external M12x1.25 threaded stop and lock nut lets you set the forward end position between 40mm and 60mm directly on the machine, while the return stroke remains fixed at its original 60mm. Because the piston area is unchanged, output force equals a standard ACQ of the same bore.
This unit includes a male M14x1.5 piston rod end for direct load coupling and a built-in magnet (-S) for position sensing. It features a 16mm rod, PT1/8 port, and NBR elastomer bumpers at both ends for fixed end-deceleration. The compact riveted body operates at speeds from 30-500 mm/s within a -20 to +70 C temperature range.

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X60-20SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture using the external stop, allowing rapid accommodation of different raw material widths without swapping cylinders.
Package Diverter Arms
Adjust the extend position of a routing gate on a packaging conveyor to handle varying carton lengths, ensuring items divert accurately without repositioning hardware.
Assembly Press Testing
Set trial press depths for electronic component insertion, fine-tuning the forward travel in 1mm increments to verify insertion force before finalizing the automated cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20SB the Right Cylinder?
Selecting this bore provides 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. If your application requires less force, the adjacent 32mm bore delivers 402.1 N push, whereas stepping up to the 50mm bore yields 981.8 N. A fixed-stroke ACQ40 is sufficient if your end position never varies. When ordering, confirm the 40mm bore, 60mm full stroke, 20mm window, the -S magnet, and the -B male rod 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 ACQJ40X60-20SB FAQ
At 0.5 MPa it provides 628.3 N push and 527.8 N pull force, and 879.6 N push at 0.7 MPa. The maximum push force is 128 kgf at 1.0 MPa. The usable extend range is 40-60 mm (60mm full stroke minus the 20mm window).
No, the adjuster only changes the extend length; force remains identical to a standard ACQ40. Deceleration relies on fixed NBR elastomer bumpers at each end, not adjustable air cushions. The built-in -S magnet is compatible with reed or electronic solid-state switches.
