Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm 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 ACQJ32X50-50S
The AirTAC ACQJ32X50-50S is a double-acting JIS compact cylinder with a 32mm bore and 50mm full stroke. An external M12x1.25 threaded stop and lock nut restricts the extend end position, providing a usable extend range of 0-50mm. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore. The unit includes a built-in piston magnet (-S) for position sensing and fixed elastomer bumpers at both ends. Operating pressure spans 0.15-1.0 MPa with a speed range of 30-500 mm/s.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 50 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X50-50S Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC machining fixture when raw material thickness varies, avoiding the need to swap out cylinder hardware.
Packaging Diverter Arms
Fine-tune the stroke length of a conveyor sorting gate during product format changeovers to accommodate different carton widths.
Assembly Press Testing
Establish trial end positions on an electronic assembly press, testing engagement depths precisely before locking down the stop nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50S the Right Cylinder?
This 32mm bore delivers 402.1N push and 301.6N pull at 0.5 MPa. If your application needs less force, the 25mm bore provides 245.4N push; for higher loads, the 40mm bore offers 628.3N push. Choose a fixed-stroke ACQ if end-position tuning is unnecessary. To order, confirm the 32mm bore, 50mm full stroke, 50mm window, -S magnet, and female M8x1.25 rod end.
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 ACQJ32X50-50S FAQ
It provides 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 50mm with a 50mm window, allowing an adjustable extend range of 0-50mm.
The external M12x1.25 threaded stop limits only the extend stroke length; force remains identical to a standard ACQ. Fixed elastomer bumpers handle end-of-stroke deceleration, and the built-in -S magnet is compatible with reed or electronic solid-state switches.
