Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 15mm 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 ACQJ32X15-20B
The AirTAC ACQJ32X15-20B is a double-acting JIS compact cylinder featuring a male-thread piston rod end (M14x1.5) that couples directly to your load. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 0-15 mm (15 mm full stroke minus the 20 mm adjustment window). The retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The cylinder body uses a fixed elastomer NBR bumper at each end for end-of-stroke deceleration and includes sensor grooves, though this specific configuration ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 15 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 ACQJ32X15-20B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining center during setup, allowing operators to fine-tune the 0-15 mm end position without swapping cylinder bodies.
Product Changeover Guides
Adjust the extend stop rapidly on a packaging line when switching between carton sizes, using the external M12x1.25 adjuster to set new end limits on the fly.
Trial End Positions
Test various extend endpoints on assembly machinery to find the optimal pressing distance, relying on the 82 kgf maximum push force to move the load.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20B the Right Cylinder?
This 32 mm bore cylinder provides 402.1 N push force at 0.5 MPa, sitting between the smaller 25 mm bore (245.4 N push) and the larger 40 mm bore (628.3 N push). If your application requires a fixed 15 mm extend stroke without on-the-fly adjustments, a standard ACQ32X15 cylinder will suffice. When ordering this adjustable version, confirm the 32 mm bore, 15 mm full stroke, 20 mm window, the male rod thread (-B), and whether you require the -S magnet option for position sensing.
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 ACQJ32X15-20B FAQ
This cylinder delivers 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 is 0-15 mm (15 mm full stroke minus the 20 mm window), while the retract stroke remains unaffected.
The external M12x1.25 threaded stop with a lock nut limits the extend stroke length only; it does not change the piston area or force. The cylinder uses a fixed elastomer NBR bumper at each end for deceleration rather than an adjustable air cushion. Note that this model ships without a sensor magnet, though the body retains sensor grooves for adding switches if needed.
