Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-10B
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 80mm 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 ACQJ20X80-10B
The AirTAC ACQJ20X80-10B is a double-acting JIS compact cylinder with an 80mm full stroke and a male-threaded (M8x1.25) piston rod end. An external M8x1.25 threaded stop and lock nut limit the extend end position, providing a usable extend range of 70-80mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, output force equals a standard ACQ of the same bore.
Operating pressure ranges from 0.15 to 1.0 MPa, and the body features fixed elastomer TPU bumpers at both ends rather than adjustable air cushions. The M5x0.8 port and 10mm rod keep the envelope compact, while integrated sensor grooves allow for position detection if a separate magnet is added later. This unit ships without a magnet.

| Rod thread | M5×0.8 (F) / M8×1.25 (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 (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 ACQJ20X80-10B Is Used
Machining Fixture Stops
Dial in the extend position from 70 to 80mm on the fly to accommodate varying raw material lengths without machining new spacer blocks.
Product Changeover Diverters
Quickly retune the rod extension stop when switching a packaging line between different carton widths or product profiles.
Prototype End Positions
Safely trial different extend endpoints on a test rig by limiting the outward travel, preventing crashes during mechanism development.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-10B the Right Cylinder?
Selecting this 20mm bore actuator yields 157.1N push and 117.8N pull at 0.5MPa. If your application requires less force, stepping down to a 16mm bore provides 100.5N push, whereas moving up to a 25mm bore offers 245.4N push. A standard fixed-stroke ACQ is sufficient if your end position never varies. When ordering this adjustable version, confirm the 80mm full stroke, 10mm window, male M8x1.25 rod thread, and the absence of a 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-10B FAQ
This cylinder delivers 157.1N push and 117.8N pull at 0.5MPa, 219.9N push at 0.7MPa, and a maximum push of 32kgf at 1.0MPa. The full stroke is 80mm, and with the 10mm adjustment window, the usable extend range is 70-80mm.
The external M8x1.25 threaded stop with lock nut mechanically limits the extend distance without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end deceleration, and because it lacks a rod lock, the load will drift if air pressure is lost.
