About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75S
The AirTAC ACQJ80X80-75S is a double-acting JIS compact cylinder with an external extend stop. A threaded M20x1.5 adjuster and lock nut lets you set the forward end position anywhere from 5 to 80 mm. The return stroke remains fixed at the full 80 mm.
Because the piston area is unchanged, output force matches a standard ACQ of this bore: 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit uses a 25 mm rod, PT3/8 port, and fixed NBR elastomer bumpers. The -S magnet enables tracking with reed or solid-state 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 ACQJ80X80-75S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC mill fixture without machining new spacers for every part batch.
Carton Changeover
Adapt the folding flap contact point on a packaging line quickly when moving between different box sizes.
Press Trial Positions
Test various end-of-stroke touch points on an assembly press safely before finalizing the mechanical hard stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75S the Right Cylinder?
For lighter jobs, the 63 mm bore yields 1558.6 N push at 0.5 MPa, while the 100 mm bore provides 3927.0 N if you need more power. If your extend target never varies, a fixed ACQ80 cylinder is simpler. To order this unit, confirm the 80 mm bore, 80 mm full stroke, 75 mm window, S magnet, 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 ACQJ80X80-75S 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 full stroke is 80 mm with a 75 mm window, yielding a usable extend range of 5 to 80 mm.
An external M20x1.5 threaded screw with a lock nut limits the forward travel, leaving the retract stroke unaffected. The adjuster changes stroke length only, so force remains identical to a standard ACQ. Fixed elastomer bumpers absorb end impacts, and the S magnet works with reed or solid-state switches.
