Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 60mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30
The AirTAC ACQJ20X60-30 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 30 mm up to the full 60 mm stroke directly on the machine, while the retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This 20 mm bore unit features a 10 mm piston rod, an M5x0.8 port, and an M8x1.25 male rod-end thread. It includes fixed elastomer bumpers at both ends for end-of-stroke deceleration and integrated sensor grooves, though this specific configuration ships without a magnet. Operating pressure ranges from 0.15 to 1.0 MPa, with a maximum push force of 32 kgf at 1.0 MPa.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30 Is Used
Machining Fixture Stops
Dial in the exact extend position from 30 to 60 mm to accommodate varying raw material thicknesses on a CNC milling fixture without swapping mechanical parts.
Carton Changeover Flaps
Quickly reposition the extend end stop to fold different carton heights on a packaging line, using the external M8x1.25 adjuster to hit the precise 45 mm mark.
Prototype Press Tonnage
Test multiple trial end positions for a light-duty assembly press, relying on the fixed elastomer bumper to absorb the 157.1 N impact at 0.5 MPa.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30 the Right Cylinder?
If you need slightly less force, the 16 mm bore provides 100.5 N push at 0.5 MPa, whereas stepping up to a 25 mm bore yields 245.4 N push. This 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient, but this adjustable version is ideal for setups requiring on-the-fly position changes. When ordering, confirm the 60 mm full stroke, the 30 mm adjustment window, the female rod thread, and whether you need the -S magnet option for 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-30 FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, the push force is 219.9 N. The maximum push force is 32 kgf at 1.0 MPa. The full stroke is 60 mm, and with the 30 mm adjustment window, the usable extend range is 30 to 60 mm.
No, the external threaded stop only limits how far the rod extends; the piston area remains the same, so the output force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers at both ends for deceleration rather than adjustable air cushions, so for high-energy loads you should slow the approach or add an external shock absorber.
