Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50S 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 ACQJ80X70-50S
The ACQJ80X70-50S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can tune the usable extend range from 20 mm up to the full 70 mm directly on the machine without swapping parts, while the retract stroke remains 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 stroke length and not the piston area, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit includes fixed elastomer bumpers for end-of-stroke deceleration and a built-in magnet (-S) compatible with reed or solid-state electronic switches.

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 ACQJ80X70-50S Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC machining center to accommodate raw castings of varying widths without fabricating custom spacer blocks.
Packaging Diverter Stops
Adjust the extend stop on a packaging line diverter to handle different carton depths, ensuring positive product positioning during format changeovers.
Press Pin Insertion Depth
Fine-tune the downward insertion depth of a pin press during prototype runs to find the optimal seating position before locking the nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-50S the Right Cylinder?
Select this 80 mm bore actuator when your setup requires 2513.2 N push at 0.5 MPa and on-the-fly extend length tuning within a 20-70 mm window. If your application needs less force, stepping down to a 63 mm bore yields 1558.6 N push, whereas a 100 mm bore provides 3927.0 N push for heavier loads. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, verify the 70 mm full stroke, 50 mm window, S magnet option, and female M16x2.0 rod thread.
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 ACQJ80X70-50S FAQ
It delivers 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 50 mm window provides a usable extend range of 20-70 mm.
The external M20x1.5 threaded stop with lock nut mechanically limits the extend length, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers absorb end-of-stroke impact, and the -S magnet works with reed or solid-state switches.
