Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ50X200-20S
The AirTAC Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ50X200-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø50mm bore and 200mm 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 ACQJ50X200-20S
The AirTAC ACQJ50X200-20S is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut to limit the extend end position. With a full stroke of 200 mm and a 20 mm adjustment window, you can fine-tune the usable extend range from 180 mm up to 200 mm directly on the machine. The retract stroke remains completely unaffected. This long-stroke made-to-order variant exceeds the 100 mm standard maximum for this bore, extending up to the 300 mm range.
Because the adjuster only alters travel length and not the piston area, the output force stays identical to a standard ACQ of the same bore. At 0.5 MPa it delivers 981.8 N of push force and 824.6 N of pull force. The unit includes a built-in piston magnet for electronic or reed switches, fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and a PT1/4 port.

| 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 ACQJ50X200-20S Is Used
Machining Fixture Stops
Dial in the exact 180 to 200 mm extend position on a CNC machining fixture without swapping parts during setup changes or product changeovers.
Transfer Line Diverter
Adjust the stroke length on a packaging transfer line to accommodate varying carton sizes while maintaining the full 981.8 N push force.
Assembly Press Positioning
Set precise trial end positions for an assembly press, relying on the fixed NBR bumper to decelerate the tooling near the end of travel.
Is the Airtac Adjustable Compact Cylinder ACQJ50~63 ACQJ50X200-20S the Right Cylinder?
If the 981.8 N push force at 0.5 MPa is too high, stepping down to a 40 mm bore yields 628.3 N, while a 63 mm bore provides 1558.6 N for heavier loads. A fixed-stroke ACQ cylinder is sufficient if your end position never requires on-machine tweaking. When ordering this adjustable variant, confirm the 50 mm bore, 200 mm full stroke, 20 mm window, the -S magnet option, and the default female M10x1.5 rod-end thread. Remember that a plain ACQ-type cylinder will not hold a load on air loss; for fail-safe positioning, add an external rod lock or pilot-operated check valve.
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 ACQJ50X200-20S FAQ
This 50 mm bore cylinder delivers 981.8 N push and 824.6 N pull at 0.5 MPa, 1374.4 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa. The full stroke is 200 mm with a 20 mm adjustable window, giving a usable extend range of 180-200 mm. Operating pressure is 0.15-1.0 MPa.
The external M16x1.5 threaded stop with a lock nut limits only the extend stroke length, meaning force is identical to a standard ACQ since piston area is unchanged. The retract stroke is unaffected. Deceleration is handled by fixed elastomer bumpers at both ends, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
