Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 90mm 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 ACQJ80X90-75S
The AirTAC ACQJ80X90-75S is a double-acting JIS compact cylinder with an external extend-stop mechanism. By turning the M20x1.5 threaded adjuster rod and locking the nut, you set the forward stroke anywhere from 15 mm up to the full 90 mm. The return stroke remains fixed at its original length. Because the piston area stays constant, output force is identical to a standard ACQ of this bore.
This 80 mm bore actuator pushes with 2513.2 N and pulls with 2267.8 N at 0.5 MPa. It features a 25 mm piston rod, a female M16x2.0 rod-end thread, and a PT3/8 port. Fixed NBR elastomer bumpers absorb impact at both ends, while the built-in magnet (-S) pairs directly 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 ACQJ80X90-75S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture without machining new spacers, accommodating raw part variations directly on the machine.
Packaging Changeover
Rapidly reposition the product pusher when switching carton sizes on a filling line, using the external stop to set new extend endpoints in seconds.
Press Load Trialing
Test different pressing depths on an assembly station by adjusting the forward stroke limit, preventing over-travel during prototype runs.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75S the Right Cylinder?
Choose this 80 mm bore if your setup requires 2513.2 N of push force at 0.5 MPa along with variable end positioning. If you need less thrust, the 63 mm bore provides 1558.6 N push; stepping up to the 100 mm bore yields 3927.0 N. A fixed-stroke ACQ cylinder is sufficient when your extend position never requires tweaking. To order, confirm the 90 mm total stroke, the 75 mm adjuster window, the -S magnet, and the female 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 ACQJ80X90-75S FAQ
At 0.5 MPa it pushes with 2513.2 N and pulls with 2267.8 N; at 0.7 MPa push is 3518.5 N. Maximum push is 513 kgf at 1.0 MPa. The usable extend range is 15-90 mm (90 mm full stroke minus the 75 mm adjustment window).
No, the external M20x1.5 threaded stop only limits the forward travel distance, leaving the piston area and output force identical to a standard ACQ. The actuator uses fixed NBR elastomer bumpers at both ends for deceleration, and the -S magnet works with reed or electronic switches.
