Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30B 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 ACQJ80X50-30B
The AirTAC ACQJ80X50-30B is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut to fine-tune the extend end position. With a 50mm total stroke and a 30mm adjustment window, the usable extend range spans 20mm to 50mm. The retract stroke remains completely unaffected by this external stop.
Because the adjustment mechanism only limits travel length, the piston area stays the same, meaning output force is identical to a standard ACQ of this bore. At 0.5 MPa it delivers 2513.2N of push force and 2267.8N of pull force. This variant includes a male M22x1.5 rod-end thread for direct load coupling and relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 50 mm |
| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| 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 ACQJ80X50-30B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining center during part changeovers without machining new spacers or swapping cylinders.
Packaging Tucking Arms
Adjust the tucking depth on a carton sealing line to accommodate different box heights, preventing crush damage while maintaining secure folds.
Press Positioning
Set precise lower dead centers on light assembly presses where material thicknesses vary, ensuring consistent contact without reprogramming the machine.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30B the Right Cylinder?
If you require slightly less force, the adjacent 63mm bore yields 1558.6N push at 0.5 MPa, whereas stepping up to the 100mm bore provides 3927.0N push. Selecting this 80mm bore is ideal when your application demands roughly 2.5kN of thrust. A fixed-stroke ACQ cylinder is sufficient if your end position never changes, but this ACQJ model is necessary for on-machine adjustability. Confirm your ordering criteria including the 50mm full stroke, 30mm window, male rod thread (-B), and PT3/8 port size. Note that this specific unit ships without a magnet.
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 ACQJ80X50-30B FAQ
This 80mm bore cylinder provides 2513.2N push and 2267.8N pull at 0.5 MPa, 3518.5N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The total stroke is 50mm with a 30mm window, allowing an adjustable extend range of 20mm to 50mm.
The external M20x1.5 threaded stop limits only the extend length, meaning the output force is identical to a standard ACQ cylinder. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not an adjustable air cushion, so you may need an external shock absorber for high-energy loads.
