Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B
The AirTAC Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø63mm bore and 35mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B
The ACQJ63X35-30B 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 5 to 35 mm directly on the machine without swapping parts, while the retract stroke remains completely unaffected. Because the piston area stays the same, the output force is identical to a standard ACQ of this bore.
This bore 63 unit features a 20 mm piston rod, PT1/4 porting, and a male M18x1.5 rod-end thread for direct load coupling. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. The body incorporates fixed elastomer NBR bumpers at each end and includes sensor grooves, though this specific configuration ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø63 mm |
| Full stroke | 35 mm |
| Adjuster thread | M16×1.5 |
| Port size | PT1/4 |
| 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 | M10×1.5 (F) / M18×1.5 (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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B Is Used
Machining Fixture Stops
Dial in the exact extend position from 5 to 35 mm on a CNC machining fixture to accommodate varying raw part dimensions without machining new stop collars.
Carton Changeover Flaps
Adjust the extend end stop on the fly during packaging format changeovers to securely fold different carton sizes on a single line.
Assembly Press Testing
Set trial end positions for a press operation during new product introduction, tweaking the 5-35 mm extend range until the optimal insertion depth is found.
Is the Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B the Right Cylinder?
Choosing this bore 63 unit gives a 0.5 MPa push force of 1558.6 N. If your application requires less force, stepping down to a bore 50 yields 981.8 N push, whereas moving up to a bore 80 provides 2513.2 N. Opt for a fixed-stroke ACQ cylinder if your end position never requires adjustment. When ordering, confirm the 35 mm full stroke, the 30 mm adjustable window, the male M18x1.5 rod thread, and note that the -S magnet is omitted here.
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 Adjustable Compact Cylinder ACQJ50~63 ACQJ63X35-30B FAQ
It provides 1558.6 N push and 1401.5 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum push of 318 kgf at 1.0 MPa. The full stroke is 35 mm with a 30 mm window, allowing a usable extend range of 5-35 mm. The retract stroke is unaffected.
The external M16x1.5 threaded stop with a lock nut limits only the extend length, leaving piston area and force unchanged. Deceleration relies on fixed elastomer bumpers, not an adjustable air cushion. Note that a plain ACQ-type cylinder will not hold its load on air loss; install an external rod lock or pilot-operated check valve for fail-safe holding.
