Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X10-10
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X10-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 10mm 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 ACQJ20X10-10
The AirTAC ACQJ20X10-10 is a double-acting JIS compact cylinder with a 10 mm full stroke and a 10 mm adjustment window, allowing the extend end position to be fine-tuned on the machine anywhere from 0 to 10 mm. An external M8x1.25 threaded stop with a lock nut limits the outward travel, while the retract stroke remains completely unaffected.
Because the adjustment only restricts physical travel, the piston area stays the same, meaning the output force is identical to a standard ACQ of this bore. At 0.5 MPa it generates 157.1 N of push force and 117.8 N of pull force, operating through an M5x0.8 port. The body incorporates fixed elastomer TPU bumpers at both ends for end-of-stroke deceleration and includes magnetic-switch grooves, though this specific unit ships without a magnet.

| Bore size | Ø20 mm |
| Full stroke | 10 mm |
| Adjuster thread | M8×1.25 |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ20X10-10 Is Used
Micro-Clamp Positioning
Dial in the exact clamping depth on small machining fixtures between 0 and 10 mm without swapping out physical components.
Electronic PCB Probing
Safely set the downward travel of a testing probe head to prevent crushing delicate circuit boards during product changeovers.
Light Pouch Sealing
Adjust the extend endpoint on a packaging line to accommodate varying material thicknesses while maintaining a consistent seal.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X10-10 the Right Cylinder?
When sizing this 20 mm bore actuator, stepping down to a 16 mm bore reduces the 0.5 MPa push force to 100.5 N, while stepping up to a 25 mm bore increases it to 245.4 N. If your application never requires end-position variation, a fixed-stroke ACQ cylinder provides the exact same holding and force characteristics in a simpler package. To order this adjustable version correctly, confirm the 20 mm bore, 10 mm full stroke, 10 mm window, the default female M5x0.8 rod-end thread, and the standard PT port. Note that a plain cylinder will drift and lose its load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
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 ACQJ20X10-10 FAQ
This 20 mm bore cylinder provides a push force of 157.1 N and a pull force of 117.8 N at 0.5 MPa, with a push of 219.9 N at 0.7 MPa and a maximum push of 32 kgf at 1.0 MPa. The usable extend range is 0-10 mm, achieved by using the 10 mm adjustment window to shorten the 10 mm full stroke.
An external M8x1.25 threaded screw with a lock nut mechanically limits how far the rod extends, shortening the stroke without altering the piston area or output force. Deceleration is handled by fixed elastomer TPU bumpers at both ends rather than an adjustable air cushion, so for high-speed approaches an external shock absorber is recommended.
