Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40 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 ACQJ80X50-40
The AirTAC ACQJ80X50-40 is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend end position. With a full stroke of 50mm and an adjustment window of 40mm, you can fine-tune the usable extend range from 10mm up to 50mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, yielding a push of 2513.2N and pull of 2267.8N at 0.5MPa. The unit incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| 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 |

| 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 ACQJ80X50-40 Is Used
Machining Fixture Stops
Dial in the extend position from 10 to 50mm on a CNC machining fixture to accommodate varying raw casting widths without swapping out hard stops.
Packaging Changeover
Rapidly adjust the extend end point during product format changeovers on a packaging line to push different carton sizes into the sealing station.
Assembly Press Trials
Safely test and set the exact extend end position for a pressing operation during initial machine commissioning before locking down the M20x1.5 adjuster nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40 the Right Cylinder?
When sizing this 80mm bore actuator, note that stepping down to a 63mm bore drops the 0.5MPa push force to 1558.6N, while moving up to a 100mm bore increases it to 3927.0N. If your application never requires end-position variance, a fixed-stroke ACQ cylinder provides the same holding power in a simpler package. For this adjustable model, verify your ordering essentials: 80mm bore, 50mm full stroke, 40mm adjustment window, female M16x2.0 rod thread, and PT3/8 porting.
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 ACQJ80X50-40 FAQ
At 0.5MPa it provides 2513.2N push and 2267.8N pull; at 0.7MPa push is 3518.5N, with a maximum push of 513kgf at 1.0MPa. The 50mm full stroke can be shortened by up to 40mm, giving a usable extend range of 10-50mm.
An external M20x1.5 threaded stop with a lock nut physically limits the extend travel, meaning force is identical to a standard ACQ since piston area is unchanged. The cylinder uses fixed elastomer bumpers for deceleration, and because it lacks a lock mechanism, the rod will drift on air loss unless an external rod lock is installed.
