Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30S 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 ACQJ80X80-30S
The AirTAC ACQJ80X80-30S 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 50 to 80 mm on the machine, while the retract stroke remains completely unaffected. The adjuster features an M20x1.5 thread.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. The 80 mm bore delivers 2513.2 N push and 2267.8 N pull at 0.5 MPa. It includes a built-in piston magnet for position sensing and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ80X80-30S Is Used
Machine Tool Changeover
Dial in the extend stop precisely when swapping machining fixtures on a milling line, avoiding the need to fabricate custom spacer rings for each part.
Variable Carton Sealing
Accommodate different box heights on a packaging conveyor by tweaking the extend end position to press sealing heads without crushing the cardboard.
Press Fit Trials
Establish the exact insertion depth for bearing press operations during initial setup, allowing operators to test end positions before finalizing the mechanical stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30S the Right Cylinder?
When sizing this unit, consider the 63 mm bore for lighter loads, providing 1558.6 N push at 0.5 MPa, or step up to the 100 mm bore for 3927.0 N push if your application requires more power. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version, confirm the 80 mm bore, 80 mm full stroke, 30 mm adjuster window, the S magnet option, and the female M16x2.0 rod-end 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 ACQJ80X80-30S FAQ
It provides 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 30 mm adjustable window, yielding a usable extend range of 50 to 80 mm.
The external threaded stop with a lock nut physically limits how far the rod extends, shortening the stroke length without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, and the included S magnet works with reed or electronic solid-state switches.
