Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30
The AirTAC ACQJ80X50-30 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 travel from 20 mm up to the full 50 mm directly on the machine without changing parts. 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, yielding 2513.2 N push at 0.5 MPa. The unit features a 25 mm piston rod, a PT3/8 port, and fixed elastomer bumpers at both ends rather than adjustable pneumatic cushions. Body sensor grooves are built-in, but this specific configuration ships without a magnet.

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

| Rod thread | M16×2.0 (F) / M22×1.5 (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30 Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part sizes on a CNC machining center without machining custom spacer blocks.
Packaging Diverter Arms
Adjust the stroke length on a packaging line diverter to handle different carton widths during rapid product changeover.
Assembly Press Tonnage
Set precise trial end positions on an assembly press for seating bearings, preventing overtravel damage to components.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30 the Right Cylinder?
For 0.5 MPa operations, this 80 mm bore generates 2513.2 N of push force. If your application requires less force, step down to the 63 mm bore which provides 1558.6 N push, or step up to the 100 mm bore offering 3927.0 N push for heavier loads. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, confirm the 50 mm full stroke, the 30 mm adjustable window, the female M16x2.0 rod-end thread, and that no magnet is required.
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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30 FAQ
The usable extend range is 20-50 mm via the 30 mm window. Push force is 2513.2 N and pull is 2267.8 N at 0.5 MPa, 3518.5 N push at 0.7 MPa, and max push is 513 kgf at 1.0 MPa. The retract stroke remains the full 50 mm.
An external M20x1.5 threaded stop with a lock nut limits the extend distance, changing only the stroke length and not the piston area, so force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end deceleration. Note that this model lacks a magnet, though the body retains sensor grooves for adding switches.
