Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10 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 ACQJ80X70-10
The AirTAC ACQJ80X70-10 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 range from 60 to 70 mm directly on the machine without changing parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore. The adjuster only changes the stroke length. This 80 mm bore unit features a 25 mm rod, PT3/8 porting, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ80X70-10 Is Used
Machining Fixture Stops
Dial in the exact 60 to 70 mm extend position on a milling fixture to accommodate varying raw casting dimensions without swapping mechanical spacers.
Product Changeover Limits
Quickly readjust the extend end stop on a packaging line when switching between different carton sizes, ensuring precise product alignment.
Assembly Press Tuning
Set trial end positions on an electronic component insertion press, tweaking the 10 mm window to find the optimal pressing depth before locking the nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10 the Right Cylinder?
If your application requires less force, the adjacent ACQJ63 bore provides 1558.6 N push at 0.5 MPa, while the larger ACQJ100 bore offers 3927.0 N push if you need more power. If your extend end position never varies, a fixed-stroke ACQ80 cylinder is sufficient. For this adjustable model, confirm the 70 mm full stroke, the 10 mm window, the female M16x2.0 rod thread, and whether you need 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 ACQJ80X70-10 FAQ
The usable extend range is 60 to 70 mm, set by the 10 mm window. The force is identical to a standard ACQ80: 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 external M20x1.5 threaded stop with lock nut limits only the extend stroke; the retract stroke is unaffected. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. It will not hold a load on air loss, so use an external rod lock for fail-safe holding.
