Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X90-100S
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X90-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 90mm 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 ACQJ20X90-100S
The AirTAC ACQJ20X90-100S is a double-acting JIS compact cylinder with a 90mm full stroke and a 100mm external adjustment window. An external threaded stop with a lock nut limits the extend end position, yielding a usable forward range of 0-90mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the output force equals a standard ACQ of the same bore, delivering 157.1N push and 117.8N pull at 0.5MPa. The unit features a 10mm piston rod, M5x0.8 port, and fixed elastomer bumpers at both ends. The integrated -S magnet works seamlessly with reed or solid-state electronic switches.

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 ACQJ20X90-100S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup without machining custom spacers.
Packaging Diverter Arms
Alter the stroke length quickly for different carton sizes on a packaging line changeover.
Laboratory Test Rigs
Probe samples at varying extension depths to find the optimal contact point before finalizing the design.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X90-100S the Right Cylinder?
Choosing this 20mm bore model provides 219.9N push force at 0.7MPa. If your application requires less force, the 16mm bore offers 100.5N push at 0.5MPa; for heavier loads, the 25mm bore provides 245.4N. If your end position never varies, a fixed-stroke ACQ cylinder suffices. When ordering, verify the 90mm full stroke, 100mm window, -S magnet, and default female M5x0.8 rod-end thread.
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 ACQJ20X90-100S FAQ
The usable extend range is 0-90mm. Force is identical to a standard ACQ: 157.1N push and 117.8N pull at 0.5MPa, 219.9N push at 0.7MPa, with a maximum push of 32kgf at 1.0MPa. The operating pressure is 0.15-1.0 MPa.
An external M8x1.25 threaded stop with a lock nut limits the forward stroke only; the retract stroke is unaffected. The adjuster changes stroke length, not force. Fixed elastomer bumpers decelerate the piston at both ends, and the built-in -S magnet is compatible with reed or electronic switches.
