Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 25mm 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 ACQJ32X25-10B
The AirTAC ACQJ32X25-10B is a double-acting JIS compact cylinder featuring a male-thread piston rod (M14x1.5) and a 25mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 15 to 25mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, output force equals a standard ACQ of this bore.
Operating pressure runs from 0.15 to 1.0 MPa with a PT1/8 port. The body includes fixed elastomer bumpers at each end rather than adjustable air cushions. Sensor grooves are integrated into the body, though this specific SKU ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 25 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 ACQJ32X25-10B Is Used
Product Changeover Stops
Quickly dial in the extend stop from 15 to 25mm on packaging lines when switching between different carton sizes without swapping hardware.
Setup-Varying Fixtures
Fine-tune clamping positions on machining fixtures by rotating the external M12x1.25 adjuster to find the optimal end point.
Trial End Positions
Test actuation depths during assembly machine prototyping to determine the exact extend distance before locking the nut down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10B the Right Cylinder?
When sizing this 32mm bore unit, stepping down to a 25mm bore yields 245.4N push force, while stepping up to a 40mm bore provides 628.3N push force at 0.5 MPa. If your machine requires a fixed extend end position every cycle, a standard ACQ cylinder is sufficient. For trial end positions or product changeovers, order this unit by confirming the 32mm bore, 25mm full stroke, 10mm window, male rod thread, and whether a magnet is needed.
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 ACQJ32X25-10B FAQ
This 32mm bore cylinder delivers 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 25mm with a 10mm adjustment window, allowing a usable extend range of 15 to 25mm.
The external M12x1.25 threaded stop with lock nut limits the extend length without altering piston area, keeping force identical to a standard ACQ. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions. Note that a plain cylinder does not hold its load on air loss, so an external rod lock is needed for fail-safe holding.
