Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 20mm 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 ACQJ32X20-20
The AirTAC ACQJ32X20-20 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. With a full stroke of 20 mm and a 20 mm adjustment window, the usable extend range runs from 0 to 20 mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore.
This 32 mm bore unit delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. It features a 16 mm piston rod, a PT1/8 port, and a female M8x1.25 rod-end thread. The body includes fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions, and it operates effectively between 30 and 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 ACQJ32X20-20 Is Used
Machining Fixture Clamps
Dial in the exact clamping extension on a CNC machining center without swapping cylinders when part blanks vary slightly in size.
Product Changeover Stops
Adjust the extend stroke on a packaging line conveyor diverter rapidly during product format changes to accommodate different carton widths.
Assembly Press Positioning
Set trial end positions for pressing bearings on an assembly line, allowing operators to tweak the 0-20 mm range directly on the machine.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-20 the Right Cylinder?
Selecting this 32 mm bore cylinder provides 402.1 N push at 0.5 MPa, sitting between the 25 mm bore (245.4 N push) and the 40 mm bore (628.3 N push). If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable model, confirm the 32 mm bore, 20 mm full stroke, 20 mm window, standard female rod thread, and whether you need the magnet option, as this unit ships without one.
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 ACQJ32X20-20 FAQ
This 32 mm bore cylinder delivers a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, with a push of 562.9 N at 0.7 MPa and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 20 mm with a 20 mm adjustment window, providing a usable extend range of 0-20 mm.
An external M12x1.25 threaded stop with a lock nut limits the extend length, changing only the stroke distance and not the piston area, so the force remains identical to a standard ACQ. The retract stroke is unaffected. Fixed elastomer bumpers handle deceleration, and since this model lacks a magnet, you must add one for sensor grooves to function.
