Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X20-10SB
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X20-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 20mm 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 ACQJ20X20-10SB
The AirTAC ACQJ20X20-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the forward end position on the machine without swapping parts, yielding a usable extend range of 10-20 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. The M8x1.25 male piston rod end couples directly to your load, while the fixed elastomer bumper decelerates movement at both ends. An integrated magnet (-S) enables position sensing with reed or solid-state switches in the body grooves.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ20X20-10SB Is Used
Machine Tending Setup
Dial in the exact 10-20 mm extend position during initial commissioning of a lathe loading arm without machining new spacers.
Product Changeover Stops
Quickly alter the forward stop distance on a packaging line when switching between different carton depths.
Prototype End Positions
Test various extend endpoints on a lab automation rig to find the optimal pushing distance before finalizing the design.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X20-10SB the Right Cylinder?
Selecting this 20 mm bore actuator provides 157.1 N push and 117.8 N pull at 0.5 MPa. If your application requires less force, stepping down to a 16 mm bore yields 100.5 N push, whereas moving up to a 25 mm bore provides 245.4 N push. If you never need to alter the forward endpoint, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 20 mm full stroke, 10 mm adjustment window, the -S magnet, and the -B male rod 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 ACQJ20X20-10SB FAQ
This cylinder delivers 157.1 N push and 117.8 N pull at 0.5 MPa, 219.9 N push at 0.7 MPa, and a maximum push of 32 kgf at 1.0 MPa. The full stroke is 20 mm with a 10 mm adjustable window, allowing a usable extend range of 10-20 mm.
No, the external M8x1.25 adjuster screw only changes the extend length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration and includes a piston magnet for reed or electronic switches.
