Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 125mm 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 ACQJ32X125-100B
The ACQJ32X125-100B is a double-acting JIS compact cylinder featuring a 125 mm stroke and a male M14x1.5 rod end. It is a long-stroke made-to-order variant, exceeding the standard 100 mm maximum for this 32 mm bore. An external M12x1.25 threaded stop and lock nut limits the extend end position, yielding a usable forward range of 25 to 125 mm without swapping parts.
Output force remains identical to a standard ACQ of equivalent size, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The retract stroke stays completely unaffected by the adjuster. Deceleration relies on fixed NBR elastomer bumpers at both ends, and while this specific unit ships without a magnet, the body retains sensor grooves for adding solid-state or reed switches if needed later.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-100B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 125 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 ACQJ32X125-100B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC lathe by turning the external stop, accommodating raw blanks of varying lengths without fabricating custom spacers.
Carton Changeover Tamping
Adjust the extend depth on the fly when a packaging line switches to a different box height, ensuring consistent pressing force without altering the PLC program.
Assembly Press Positioning
Set precise trial end positions for pressing bearings on an automated assembly line, allowing operators to fine-tune insertion depth directly on the machine.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-100B the Right Cylinder?
When sizing this actuator, stepping down to a 25 mm bore yields 245.4 N push, while stepping up to a 40 mm bore provides 628.3 N push at 0.5 MPa. Choose this adjustable model if your fixture setup requires frequent trial end positions or product-changeover stops; a fixed-stroke ACQ suffices for static reach tasks. Confirm your ordering essentials: 32 mm bore, 125 mm full stroke, 100 mm window, male rod thread, and no magnet.
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 ACQJ32X125-100B FAQ
This 32 mm bore 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 125 mm stroke can be shortened by up to 100 mm via the external stop, giving a usable extend range of 25-125 mm.
The M12x1.25 external stop alters only the extend stroke length, leaving piston area and force unchanged from a standard ACQ. Retract stroke is unaffected, and deceleration is handled by fixed NBR elastomer bumpers rather than adjustable air cushions.
