Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm 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 ACQJ80X80-50
The AirTAC ACQJ80X80-50 is a double-acting JIS compact cylinder featuring an external extend stop. A threaded rod with a lock nut lets you shorten the forward stroke by up to 50 mm, yielding a usable extend range of 30 to 80 mm. The return stroke remains fixed at the full 80 mm. This on-machine tuning eliminates the need for different components when setups vary.
Because the piston area is unaltered, output force matches a standard ACQ of this bore exactly: 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit incorporates fixed elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. It features a 25 mm piston rod, a PT3/8 port, and an M20x1.5 adjuster thread. Note that this specific configuration ships without a piston magnet, though the body retains sensor grooves for adding external reed or solid-state switches if needed later.

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 ACQJ80X80-50 Is Used
Fixture Depth Tuning
Dial in exact clamping depth on machining centers without swapping cylinders when workpiece heights change.
Product Changeover Stops
Adjust the extend position rapidly on packaging lines to handle different carton lengths on the fly.
Assembly Press Trials
Set precise engagement distances during new product line commissioning to prevent over-travel damage.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50 the Right Cylinder?
If 2513.2 N of push at 0.5 MPa is excessive, step down to the 63 mm bore, which delivers 1558.6 N. If your application requires more thrust, the 100 mm bore provides 3927.0 N. A fixed-stroke ACQ80 is sufficient if your end position never varies. When ordering, verify the 80 mm bore, 80 mm full stroke, 50 mm window, female rod-end thread, and confirm no magnet is installed.
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 ACQJ80X80-50 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 usable extend range is 30 to 80 mm, created by subtracting the 50 mm window from the 80 mm full stroke.
The stop only limits forward travel; it does not alter piston area, so force remains identical to a standard ACQ. The retract stroke stays at the full 80 mm. End-of-travel energy is managed by fixed NBR elastomer bumpers, not adjustable air cushions.
