Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 70mm 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 ACQJ80X70-50
The AirTAC ACQJ80X70-50 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the rod extension on the machine across a usable range of 20 to 70 mm, while the retract stroke remains completely unaffected. It features a 25 mm piston rod, a PT3/8 port, and a female M16x2.0 rod-end thread.
Because the adjuster only alters travel length and not the piston area, the output force stays identical to a standard ACQ of this bore. You get 2513.2 N of push and 2267.8 N of pull at 0.5 MPa. The body incorporates fixed elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions.

| Model | Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 70 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 ACQJ80X70-50 Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC lathe loading arm without machining new spacer blocks during part changeovers.
Carton Forming Arms
Adjust the pusher end-point on the fly to handle varying package depths on a packaging line without swapping cylinders.
Press Tooling Setup
Find the optimal trial end position for a stamping or press tool quickly, then lock the M20x1.5 adjuster nut in place.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50 the Right Cylinder?
If you need less thrust, the ACQJ63 bore delivers 1558.6 N push at 0.5 MPa, whereas stepping up to the ACQJ100 bore provides 3927.0 N. Choose this 80 mm bore when your fixture requires roughly 2513.2 N of push force at 0.5 MPa and a maximum standard stroke of 100 mm satisfies your motion requirements. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 70 mm full stroke, the 50 mm adjustment window, the female M16x2.0 rod thread, and whether you require the -S magnet option.
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 ACQJ80X70-50 FAQ
It provides 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The full stroke is 70 mm with a 50 mm window, giving a usable extend range of 20 to 70 mm.
An external M20x1.5 threaded stop with a lock nut limits how far the rod extends, shortening the stroke without changing the piston area or force. The cylinder uses fixed elastomer bumpers at each end for deceleration rather than adjustable air cushions.
