Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100B 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 ACQJ80X80-100B
The AirTAC ACQJ80X80-100B is a double-acting JIS compact cylinder with an external M20x1.5 threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 0 up to 80 mm directly on your machinery without swapping parts. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. This version includes a male M22x1.5 piston rod end for direct load coupling and features NBR elastomer bumpers at both ends for end-of-stroke deceleration. The body incorporates sensor grooves, though this specific SKU ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 80 mm |
| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ80X80-100B Is Used
Machining Fixture Stops
Dial in the extend position from 0 to 80 mm on CNC machining fixtures to accommodate raw material casting variations without fabricating custom spacer blocks.
Carton Changeover Flaps
Adjust the extend endpoint on packaging lines during carton size changeovers, ensuring precise folding pressure for varying box dimensions.
Press Trial Positions
Set trial end positions on light assembly presses, allowing operators to safely test stroke depths and contact points before finalizing a hard mechanical stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100B the Right Cylinder?
When sizing this unit, consider the 80 mm bore against adjacent options: a 63 mm bore yields 1558.6 N push at 0.5 MPa, while stepping up to 100 mm provides 3927.0 N. Choose this 80 mm model when your application requires exactly 2513.2 N of push force at 0.5 MPa alongside variable extend positioning. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient and simpler. To order, confirm the 80 mm bore, 80 mm full stroke, 100 mm adjustment window, the male M22x1.5 rod thread, and the absence of a magnet.
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 ACQJ80X80-100B FAQ
The usable extend range is 0-80 mm. Force is identical to a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and maximum push is 513 kgf at 1.0 MPa. The 100 mm adjustment window only shortens the extend stroke, not the force.
An external M20x1.5 threaded stop with a lock nut mechanically limits the extend length, while the retract stroke stays unaffected. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. As a standard double-acting cylinder, it will not hold a load if air pressure is lost; use an external rod lock or pilot-operated check valve for fail-safe holding.
